Follow the steps outlined in your sign’s maintenance manual to clean off any dirt, grime, insects, cobwebs or other contaminants. Don’t assume that any old cleaner will do ‒ the material could react badly and suffer damage from certain cleaning chemicals. When in doubt, you can always call a signage professional.
It’s a dirty job, but someone’s gotta do it, and it’s much easier done in the fall than in winter!
2. Replace Burned Out Bulbs
Swap out your dim or flickering bulbs before the temperature falls! As winter gets closer and the days get longer, you’ll need your electric sign to shine as bright as can be.
Mounting a ladder to replace burnt-out lamps requires a great deal of care and caution at any time of year. Doing it in the winter, when surfaces are slippery and the cold nips your fingers, only adds to the risk of injuries and broken bulbs.
3. Repaint, Reseal and Refresh
Notice a few spots where the paint has chipped or the colour has faded? The nasty weather only accelerate this kind of deterioration, adding to the expense of touching up your sign next spring.
Now’s the best time to deal with any chips, cracks or faded areas and apply a new coat of weatherproof seal to protect your signage from snow and ice.
By the way...have you noticed condensation building up inside your electric sign? Has it taken on water during the last few rainfalls? Then it’s definitely time to look at having the sign resealed, too.
Once winter comes, any moisture inside the sign will freeze, expand and unfreeze as the temperature swings.
4. Protect Your Electric Sign from Power Surges
Between fallen branches, heavy wind and road accidents, the odds of power lines arcing this winter is high. This increases the risk of a nearby power surge, which can take out your sign’s electrical components in an instant.
Make sure your signage is properly grounded and equipped with surge protection.
5. Inspect the Structure from Top to Bottom
If recent history has taught us anything, it’s to never underestimate winter’s wrath.
We’ve been through a series of particularly nasty storms the past few winters in Ontario that have ripped trees from their roots and snapped huge branches like twigs. You don’t want your sign getting caught in that kind of weather if it’s in poor condition to begin with. Remember: you could be in a lot of hot water if your sign breaks loose in heavy winds and damages someone’s property.
Before the ground is covered with snow, have your signage inspected from top to bottom by a sign service professional. This will include checking for broken or loose fittings, replacing rusty chains and wires, and ensuring the sign is fully secured to its structure.

The sign for your business is one of the most important elements of your property.
Your sign is the first impression, the introduction to your company. A clean and pristine sign gives the impression of a quality business with quality products.
Not only does it help build your brand awareness but it actually is passively marketing for you. Based on a FedEx survey, 8 out of 10 people went into a new store purely based on the fact that they like the signage.
If your sign isn’t what it used to be, it’s time to change that! Learn how to make your electrical sign look brand new!
1. Make it Safe
Safety is the number one most important thing when dealing with electric signs.
Make sure the area is secure, away from any pedestrians, with a roped off area. Ensure there is enough space to get the job done safely for you and everyone else.
2. Preparing the Sign
It’s now time to get our hands dirty!
Remove the components necessary to ensure everything is accessible. This would include:
Hardware and brackets
Exterior frames and panels
By doing this step, you give complete access to the nooks and crannies of the sign that you normally couldn’t get at. This guarantees the most thorough clean.
During the dismantling process, it’s important to take the time to inspect the components of the sign. If any are in disrepair, now’s the time to fix them or replace them.
Not only will this extra step save you time but it will also save money. You can catch any problems before they become hazardous or beyond repair. It is recommended that you check:
These components in particular are offenders of wearing down over time from the elements.
3. Cleaning the Sign
Let’s make that sign sparkle!
Often times, dirt and grim is not just on the surface, it’s also inside the sign giving it a cloudy appearance. So, scrub the interior and exterior of the sign for the best results.
When cleaning any sign, it is recommended that you use a soft cloth and gently wash with lukewarm water using an up and down motion. For drying, to prevent water spotting, use a soft microfiber cloth.
You should never use paper towels, brushes or squeegees, these products may cause scratching to the sign’s surface.
One of the most common signs of an aging sign is the quality of the paint. One way of maintaining the paint of your sign is through the use of wax.
It not only will slow down the weathering process but it will also slow down the general aging of paint. We recommend you use one of the following approved waxes: Johnson Paste Wax, Turtle Wax, or Meguiar Glaze.
4. Installation of New Lights
One of the best parts of a new electrical sign is the brand new set of lights that are installed with it. It completely transforms the look and feel of the sign when all the lights are completely uniform.
If you want to make your sign look brand new again, changing the lights can take your sign to the next level.
It also ensures that there is no flickering or outages anytime soon, so you won’t have to worry for a while. It may even be beneficial to drive by your property at night to check out how the lights are doing.
5. Finishing Touches
Your sign has undergone a major makeover, so it’s about time we show that off!
Reassemble your brand new sign and make sure all the brackets, frames, and hardware are nicely secure. Loose bolts or damages frames from severe weather is one of the most common issues with signs!
Now take a step back to admire.
6. Bonus Tip: Graffiti Removal
It is recommended for the best results to treat any graffiti that occurs within the first 24 hours.
You want to use the least harsh product possible for the sign to prevent damage. Begin with a mild and nonabrasive solvent and if that does not remove the product, move up the line to harsher products.
The following products, ordered from least intense to most, are suggested for removing graffiti:
Any product that goes on the sign should be tested on a small area that won’t affect the overall picture. Once you know the product will remove the graffiti, work from the top down using a soft cloth.

Fifteen years ago, you might not have thought twice about keeping the lights on 24/7.
Today, lighting doesn’t come as cheap.
For many facilities, lighting can account for a whopping 40% of the total energy costs. That adds up quickly to the tune of thousands of dollars a month...and the price of energy in Ontario continues to rise.
What can you do about it?
Well, the most effective way to knock down your lighting costs would be to replace your existing fluorescent or metal halide lights with brand-new, ultra-efficient LED replacement fixtures. But we know that’s not something you can do on a whim. It requires planning and approval from your directors – not to mention the capital outlay.
In the meantime, there are a few things you can do to squeeze some efficiency out of your existing exterior fixtures and luminaries. Some of these strategies are easier and more cost-effective than others…but all can help to save energy, reduce your lighting costs and make your existing lights more efficient today.
Give Your Exterior Lights a Good Clean
Outdoor wall packs and pole lights are exposed to traffic, dust, bird droppings, insects and all manner of nasty weather. Cobwebs build up in the fixtures, and the luminaires themselves pick up a layer of dirt over time.
In other words, exterior lights get dirty.
There are two problems with this. First, dirt can reduce the efficiency of LEDs and various gas lamps by impeding the heat transfer process. Second, dirt can cut down the light’s output – the dirtier the lamp, the less illumination it can provide.
Sure, the rain does help to wash some of it this dirt away, but you can’t count on Mother Nature to keep your exterior lights in peak condition. It pays to have them cleaned. Cleaning your exterior lamps, light bulbs and light fixtures regularly will enhance their light output and help to ensure they’re performing as efficiently as possible.
If you’re not sure how to go about cleaning your exterior lights safely (different manufacturers will recommend different cleaning methods and products), you can always call a professional!
Install Lighting Controls
You know to switch off the lights before you leave the room. It’s just common sense.
Motion sensors to switch off lights in empty rooms
Photosensors to detect the current level of natural light in the room and dim the lights accordingly
Timers to switch the lights on/off or reduce lighting levels at pre-set times, such as after closing time
But what if you can’t change your existing infrastructure? Adding a hardwired control system to your existing outdoor lights can be expensive. Depending on your facility, it might even be impossible.
In that case, it’s possible you could still benefit from a wireless lighting control system. Instead of hardwiring each of your lights to controllers and sensors, a wireless system can relay commands between these devices wirelessly.
Eliminate Unnecessary Spill Light
Have you ever had a neighbour install ultra-bright lights that floods the whole neighbourhood?
Even if you haven’t dealt with it personally, you’ve probably heard from someone who has. Light pollution is a common nuisance in urban areas and commercial/industrial facilities are a common culprit. That’s why most municipalities have bylaws on the issue, particularly when it comes to parking lot lighting.
What you might not realize is that creating light pollution also costs you. Think about it. Every dollar you spend producing light you don’t need – whether it’s illuminating empty space or spilling onto a neighbour’s property – is money wasted.
If your outdoor wall lights or parking lot lighting strays beyond areas that need to be lit, consider retrofitting the fixtures with shielding. Shielding is generally classified by the ‘cutoff’ level, which refers to the amount of light that will shine above a 90-degree angle from the fixture. A semi-cut-off fixture will allow no more than 5% of the rated light output to spill, while a full cut-off fixture will eliminate it entirely.
Find Your Ideal Retrofit Solution
You might not be ready to upgrade your current lighting infrastructure today – but you shouldn’t wait forever. It’s no secret that upgrading to energy-efficient sources like LEDs is the most powerful way to reduce your company’s lighting expenses. Today’s LED technology can provide you impeccable colour rendition, very high efficiency and incredible longevity – and require less maintenance than fluorescent or high-pressure sodium lamps.
Looking to restore your wood, brick, concrete, stone, glass or metal surface?
Media blasting is an excellent choice to restore surfaces that have been damaged due to rust, calcium deposits, fungus and mildew, graffiti, or fire and smoke. It’s a great way to strip paint or rust from car parts in no time at all. Media blasting uses pressurized air to blast tiny pieces of material (media) out of a nozzle at a target surface.
Choosing the right blasting media for your restoration project is an extremely important decision since the wrong medium can severely damage the surface you’re working on. The rule of thumb for media blasting is to use the gentlest abrasive possible with the lowest pressure necessary to get the job done delivering a smooth even finish on your target material.
When choosing your blasting media consider its:
Particle size, and
When in doubt, it’s best to start with a gentle blasting media and work your way up to something more powerful. Pumice, corn cob grit, or walnut shells are cheap, environment-friendly, one-time use mediums. Any of these natural media are effective at cleaning fragile material.
Corn cob grit is the softest of the naturally occurring abrasives making it an ideal choice for cleaning and burnishing applications. Commonly used for jewelry, cutlery, engine parts, fiberglass and the removal of graffiti or debris from wood, brick or stone.
Aluminum Oxide is composed from small grains that have a block-like shape with hard angular edges. These long-lasting, sharp, cutting edges are very efficient at penetrating work pieces such as metals, glass, ceramic, marble, granite or other stone surfaces. It is a good media for fast etching and profiling jobs.
Aluminum Oxide is also a great material for stripping rust off from metals with minimal dust atmosphere. But because it can leave a coarse finish, it is not the best choice for work on automobiles and other vehicles.
Glass or Plastic Beads
One of the most versatile blast media available are glass beads. These small spheres of uniform size and hardness can remove substances from any base surface delivering a soft, smooth satin type finish with minimal stress. It is well suited for stainless steel applications.
Glass beads can also be reused for up to 100 more blasting applications making them a very cost-effective choice.
Safe, clean and eco-friendly, bead blast is the most effective choice to remove fungus, and stubborn calcium and mineral deposits from swimming pool tiles. It also does a great job of removing old paint from automobiles.
Acrylic, polyester, melamine or urea plastic beads are also a great alternative for automotive media blasting, each offering varying degrees of hardness and aggression.
A real workhorse, silicon carbide can tackle almost any rough sandblasting job successfully within a shorter blast time. It is the hardest abrasive blasting media available.
This very hard and sharp material is a good choice for difficult cleaning applications and is considerably cheaper than other blasting media. Silicon carbide is great for fast cutting applications and deep etching on stone, glass and other hard surfaces.
Steel Grit or Steel Shot
If you are looking for a special finish, the angular shape of steel grit makes it perfect for removing rust and paint from steel surfaces. Steel grit is commonly used in airless applications since the rounded steel shots produce limited dust.
Steel abrasive is a cost-effective media blasting alternative used on a variety of surfaces to effectively remove contaminants, texture a surface for proper adherence of a final coating, or in peening (hardening) applications.

Signs are a key part of branding any successful business. Your sign is your first opportunity to make a good first impression on potential customers, so it only makes sense to make it your best.
Crafting the perfect sign for your business does require some planning to get it right:
The first step in deciding on the right style of signage for your business is to learn about what the local regulations will allow.
Cities, townships and counties all have by-laws governing placement and installation of retail signs. It’s a good idea to become aware of any permits you need, before you start. Nothing can be more disappointing than becoming excited about a sign design, and later having to remove it!
Provincial or territorial laws govern size and placement of highway billboards, such as pole height and distance from the road. If your building is leased, or if you are located in a shopping plaza or mall, you will need approval from your landlord.
A sign is an investment. It makes sense to get the largest size and the highest quality sign you can afford. Keep in mind, it is also the least expensive but most effective form of advertising. A well-designed, well placed sign can generate huge profits, especially when part of an overall marketing strategy.
Additionally, your sign should be low-maintenance and last a number of years. It needs to work 24 hours a day, 7 days a week telling people who and where you are.
The design of your sign should be a reflection of your brand and convey the kind of services you provide. Your sign communicates with passing pedestrians and motorists as an invitation to come through your doors and do business with you. The type of sign you choose should make it easy for anyone to find you, dar or night.
You'll need to consider shape, size, structure, and materials.
Signs can come in many shapes and sizes, as small as a countertop sign, and as large as a highway billboard, illuminated or not. They can be crafted from different materials such as acrylic, lexan, wood, metal or glass, each with their own set of pros and cons
To be effective, your sign also needs to be noticeable and readable.
How you maintain your sign will reflect the image you project to your potential customers. Some signs are cirtually maintenance-free, others - such as signs made from wood may need repainting or varnishing. The visual of an illuminated sign is second to none. Keep in mind that lighted signs may need light bulbs or tubes replaced from time to time.
For energy consumption, consider an LED retrofit. LED light offer superior illumination with lower operating costs. Contact us today for a FREE estimate.
But lighting is more than just aesthetics. Lighting provides necessary safety and security for your business.
It may seem like safety and security are the same thing when it comes to lighting. But safety and security are handled differently.
So, what is the difference? How is outdoor lighting key to both safety and security?
What does Lighting Provide?
There are a few more functionality related factors that having proper lighting plays a role in.
What does light do? It brightens potential dark spaces or hiding places. Visibility is crucial to maintaining comfort within your company.
Criminals are less likely to make advancements if the area is clearly lit and the lot appears safe. Similarly, at night animals come out. They are less likely to stumble upon your property is there are heavy lights.
Safety vs. Security
Safety is related to hazards on and around the area. Typical issues regarding safety could be:
Tripping and falling
Patches of ice
When it comes to exterior lighting safety is considered vertically. This is important because the lights will point down on a horizontal surface and will reveal the ground.
Security is associated with noticing potential threats. This lighting does not stem from only being able to see the ground but also at eye level and around you.
For security, you need horizontal light that will reflect vertical surfaces. It will allow for people to recognize faces and bodies easily because light will be reflected off of them.
Depending on your needs, you may opt for more safety lighting or security lighting, but both are important to have. To create a comfortable environment for those associated with your business you must find a balance.
Why Placement Matters
A combination of each will provide appropriate light levels and provide a good design overall. Finding a compromise between both safety lighting and security lighting means that light both shines down and spreads out.
Ensure that high-traffic areas are well lit. Entrances and exits are frequented often so they should look and feel secure to both your employees and the outside world. Lights in these locations can make sure that visitors do not go unnoticed.
Uniformity is important for comfort. As we know, the human eye can adjust to varying levels of light. If the area is dark, we will adjust to that and so forth. However, what we can’t adjust immediately. Patchy lighting makes it difficult for our eyes to adjust easily.
Not only that but it helps people feel a greater sense of security because there are less areas in which are unlit.
One might think that it would just be better to have as many lights as possible of both kinds. However, unnecessary light would be both more costly and environmentally unfriendly. Additionally, too many lights can actually due harm by causing glares.
This is especially important for those who have camera security. Having lights near the cameras and where the cameras are pointing at will help make the image clearer. For unwanted guests, it can also discourage them from pursuing anything because they can see the cameras clearly.
The Importance of Maintenance
As a company, you should want to keep your property as safe as possible. Lighting is one of those safety checks.
Lights should be checked continuously to ensure all components are working properly. Any dimmed lights should be replaced, regular cleaning for brightness and repositioning from natural factors or weather.
Repairs should be taken care of throughout the year as the property needs. Things such as burnt out lights or revealed wires, should be fixed.
Additionally, there are regional litigations related to exterior lighting. According to the Toronto Municipal Code Property Standards, the following are the official by-laws regarding property exterior lighting:
Adequate artificial lighting required to maintain the level of illumination shall be provided at all times.
For parking lots, walkways, stairs, porches, verandas, loading docks, ramps or other similar areas, a minimum level of illumination of 10 lux at ground or tread level and at angles and intersections at changes of level where there are stairs or ramps
Exterior lighting fixtures and lamps shall be installed and maintained so that the work, operations or activities normally carried out can be undertaken in safety and without undue eye strain
All lighting fixtures shall be protected from damage and if necessary, to protect a lighting fixture from damage. Protective material shall be maintained in a clean condition.
Your property’s lighting should be maintained to prevent issues and maintain your site’s security.
Overall, the atmosphere of your company is changed when lighting is provided. People are more comfortable in and around your building and it discourages those who should not be there.

What is the best way to remove an existing finish? Are you cleaning or stripping concrete, wood or metal finishes?
The method you use will depend on the material you are stripping.
What is Media Blasting?
Media blasting is a surface restoration method that does a quick job of removing most paints and stains, rust, scale or gum from hard surfaces. It incorporates a blasting unit that projects compressed air with abrasive material such as walnut shells, corncob grit, sharp metal media, dry ice pellets or crushed glass at high speeds onto the surface.
The advantages of this system are that it is fast, cost-effective, and environmentally safe. Since it uses no hazardous chemicals it can be used safely in urban areas. There is little chance of water contamination since blasting media consists of organic materials or crushed glass. It does not change the PH balance in water or soil making it a 100% environmentally-friendly.
Our choice of blasting media at SignLITE is crushed glass. This recycled material is one of the most versatile general-purpose abrasives, gently removing layers of paint, grease, graffiti or rust without causing surface damage.
Though it is safe, media blasting is not a DIY project. Talk to an expert before you pick up a blasting gun yourself!
What is Chemical Stripping?
Chemical stripping incorporates chemical strippers to dissolve and remove paint, sealants, rust and grease. While the end result can be a beautiful smooth finish, it is messy, and can take a while. Most chemical strippers come in gel form, allowing them to stay in place and dry slowly. This is particularly useful for wood surfaces that include intricate carvings.
Apart from protective clothing, no special equipment is needed. While it may be user-friendly chemical stripping is not so kind to the environment. Most common chemical strippers are solvent-based and typically contain methylene chloride. Methylene chloride is a strong oxidizer, flammable and very reactive. Rubber gloves, long sleeves, mask and respirators need to be worn. Used clothing items, rags and any residue need to be safely discarded.
However, biochemical strippers based on oils from natural materials such soybeans, pinesap, or citrus trees are growing in popularity. Cleanup is with water and leaves a nice citrus smell. Newer blends of solvents keep safety in mind and will break down paints and resins leaving a clean dry finish with the no final rinse required.
There are many residential and commercial surface restoration applications for media blasting or chemical stripping such as:
Concrete, Brick or Stone
Cleaning stamped concrete driveways
Exterior or interior brick or stone walls, or patios
Fire, smoke, water or mould restoration
Cleaning graffiti, gum & grease
Pole lights and pylon signs
Heavy industrial, vehicles and machinery
Small industrial – brass, bronze, copper and aluminum
Log home restoration
Wood furniture or wooden structures

You might not pay them much mind, but the bright lights hanging above parking lots are a major part of our urban landscapes. A survey by the Canadian Urban Institute counted between 1.4 and 2.7 million parking lot luminaires installed in Ontario alone!
Well-designed parking lot lighting makes life better for everyone: it lowers the risk of accidents and property damage while providing employees and customers with a sense of safety and security.
But great lighting design isn’t just about putting lights on a pole. Smart, effective parking lot lighting provides exactly the right amount of light in exactly the right location using as little energy as possible.
For standards not addressed by local by-laws, the Illuminating Engineering Society (IES) provides guidance in the form of parking lot lighting best practices. The IES monitors and controls the standards and illumination guidelines in the North American lighting industry.
Quantity vs. Quality of Light
If your goal is to enhance visibility in the lot, simply replacing your current lights one-to-one with brighter ones might not be the solution. More light doesn’t necessarily equal better light. The quality of your parking lot lighting is just as important as the quantity.
More intense exterior lighting might increase visibility in one area, but it can also make it harder to see people and vehicles in the darker areas. Good lighting aims to decrease the contrast between light and dark areas and distribute light evenly across the space.
A well-designed parking lot creates a welcoming environment for shoppers and clients while doing the opposite for unwelcome characters. By allowing personnel and security cameras to keep watch, lighting deters property damage and other illicit activity.
This is another reason why lighting consistency matters: too much contrast or glare makes it difficult for people and surveillance equipment to properly observe the area.
Areas with high traffic (especially a mix of pedestrian and vehicle traffic, like crosswalks) do often require higher levels of light, but it is just as crucial to avoid glare and contrast in these areas. A lighting installation professional can help you select the proper luminaries and fixtures for the various parts of your property.
It can be hard to sleep when it’s bright outside, whether the brightness comes from natural light or the neighbouring parking lot.
The intrusion onto neighbouring properties (known as light trespass or spill light) is preventable through good lighting design. LED parking lot lights provide superior directional lighting and less spill than other high-bay lighting solutions. For fluorescent, metal halide or high-pressure sodium luminaires, shields can be added to block the light in certain directions.
Additionally, high-bay lights should be mounted no higher than the buildings or trees at the perimeter of the property.
Energy consumption is power multiplied by time. Reducing consumption requires that you reduce either the duration the lights are on or the energy they consume.
Fortunately, modern lighting controls have made it easier than ever to control both parts of the equation. Incorporating lighting controls at the same point you select your luminaires can help you maximize the efficiency of your parking lot lighting.
There are several lighting control solutions available for parking lots, including photosensor-based (adjusting light level depending on the amount of sunlight) and timeclock-based (adjusting light level at a set time) systems.
The term ‘media blasting’ encompasses a diverse range of methods and technologies. Although we here at Sign LITE specialize in on-site property restoration, people also use various forms of media blasting for metal finishing, vehicle restoration and more! Here’s a quick summary of the media blasting terminology you’ll encounter when it comes to our area of expertise.
Blasting media, also known as the abrasive or grit, is the material used in the media blasting process. Media comes in many kinds of materials shapes and sizes, and choice of media can have a significant impact on the results.
Media is often categorized according to its shape, size, hardness and density. Organic materials like walnut shells and corncob are great for fragile surfaces like hardwood; sharp metal media like aluminium oxide is often used for heavy-duty cleaning and etching; smooth, rounded media like sheet shot is ideal for peening metal.
Recycled crushed glass is our media of choice since it delivers an even, clean finish and is suitable for treating a range of surface materials. Crushed glass is angular but not sharp, and it produces minimal dust. This material is also inert and non-toxic.
The blasting unit is the equipment used by an operator to project compressed air and media onto a surface. The set-up varies across industries and applications. For parts finishing and equipment restoration, operators often used fixed blasting units connected to a cabinet designed to contain dust.
Since we restore surfaces on-site, Sign LITE uses a smaller, self-contained media blasting unit that can reach locations up to 200 feet away from its power source. A portable unit consists of a handheld apparatus or ‘gun’ connected to a compressor, a hopper that feeds blasting media, and a power source. The operator can adjust the flow of air and media.
Interior Media Blasting
Interior media blasting is the process of cleaning an interior surface, such as concrete floors, brick walls or metal fixtures, using media blasting. In the hands of a trained professional, certain blasting methods can be used indoors safely.
Wet blasting using crushed glass media is ideal for interior media blasting, as it produces minimal dust and is non-toxic.
Media blasting, also known as abrasive blasting, is a process by which a material is projected at high speeds onto a surface. The material (media) is propelled by the force of compressed air, water, or a combination of the two. It is cost-effective and environmentally safe, employing recyclable materials and no hazardous chemicals.
We use media blasting to means to remove rust, scale, paint, graffiti, gum, or other damage or deterioration from hard surfaces. Different types of media are suitable for different jobs – we’ve found crushed glass media ideal for cleaning pole lights, pylon signs, brick, concrete and many steel surfaces.
Watch the media blasting process in action:
Sandblasting refers to media blasting using actual sand as the blasting media. Although the terms ‘sandblasting’ and ‘media blasting’ are sometimes used interchangeably, it’s important to recognize the differences between the various methods. Sandblasting poses greater occupational and environmental hazards because it disperses silica; today, most contractors have moved towards safer alternatives like crushed glass as the medium.
Also known as hydro blasting, wet blasting is a media blasting method that produces less dust. Although it is not truly ‘dustless’, wet blasting significantly reduces the amount of dust by combining the media with water (either by moistening the media prior to blasting or dispersing water through the blasting nozzle).

Can you tell luminance from illuminance? Colour temperature from colour rendering? These are some of the terms you’ll encounter when it comes to installing outdoor lighting. Below, we’ve defined the must-know outdoor lighting terminology, including:
Colour-rendering index (CRI) measures how accurately a light source shows the colours of objects it illuminates compared to natural light. For example, the maximum potential CRI value is 100; the standard value for parking lot lighting is 65. CRI is important in outdoor lighting for spaces like car dealerships, where the colour of the products can have a significant impact on a customer’s decision to buy.
Colour Temperature and Correlated Colour Temperature
Colour temperature describes the colour appearance of a light source. With incandescent lamps and other thermal radiators, colour temperature corresponds with the actual temperature of the light source.
When it comes to gas lamps and solid-state lighting, where the temperature has no relation to the colour of light, colour temperature is measured by comparing the appearance to the light of a thermal radiator. The technical term for this is correlated colour temperature.
Colour temperature is measured in Kelvins (K). For example, the flame of a candle emits yellow light at a temperature of approximately 2,000 K; the filament of an incandescent bulb is yellow-white at 2,700 K; the sun at noon appears at around 5,000 K.
Efficacy describes the energy-efficiency of a light source based on the ratio between its luminous flux and power consumption.
Efficacy is measured in lumens per watt (lm/W). For example, a typical fluorescent lamp is 10 lm/W; a high-flux LED is 120 lm/W.
Luminous flux, or lumens, describes the amount of light a light source radiates each second under standard conditions. It is among the most common (and commonly misunderstood) measurements listed in lighting datasheets and packaging. Lumens do not describe the colour or intensity of light; only how much light the source emits.
Luminous flux is measured in lumens (lm or Φ).
Glare is an effect that occurs when the light is too bright compared to its background, light causing discomfort and reducing the ability to see. Though there are methods of calculating and predicting glare, glare it is also subjective; for example, senior citizens may have more difficulty adjusting to glare than younger viewers.
With consideration in lighting design, glare can be reduced and controlled through proper luminaire placement and use of cut-off fixtures and shields.
Illuminance measures the amount of light that falls on a surface. This measurement has largely replaced terms such as foot-candles, illumination value and illumination level. It is typically described regarding ratios of maximum-to-minimum and average-to-minimum illuminance in an area. Measuring illuminance is necessary to calculate other measurements like luminance and glare.
Illuminance is measured in luxes (lx), with one lux equalling one lumen of incident light per square metre of light-receiving surface. For example, a typical bright summer day is approximately 100,000 lux; an overcast sky would clock in at 5,000 lux; a living room may have 100 lux. One foot-candle is equal to 10.76 lux.
Luminance measures the intensity of light emitted by an object or surface. This measurement can apply to light that emits from a lamp or luminaire or a surface that reflects or transmits light, such as a window or road surface. Usually, luminance is measured from the perspective of an observer looking towards the lighted area.
Luminance is measured in candelas per square metre (cd/m2). For example, an office desk might reflect 100 cd/m2 of a desk lamp’s light; a typical fluorescent lamp may emit luminance of 5000 to 15,000 cd/m2; the surface of the sun has a luminance of 1650 cd/m2.
Luminous intensity measures the amount of light (the lumens or luminous flux) per second emitted in a specific direction.
Luminous intensity is measured in candelas (cd).
Watts (W) measure the amount of energy a lamp consumes to produce light. The lower the wattage, the less energy the lamp requires. With incandescent lamps, and a lamp with higher wattage produces more light; however, that is not the case with compact fluorescent lamps nor LEDs.
Types of Outdoor Lighting and Outdoor Lighting Components
A ballast is a device that controls the electrical current used to produce light in a gas discharge lamp such as a fluorescent light. If the ballast fails, the lamp can overheat and burn out.
A bollard is a type of lighting fixture that includes a short, ground-mounted post topped with a light source that is directed downward.
A driver controls the electrical current in a solid-state lamp, ensuring a consistent voltage level as the number of LEDs in the circuit increases or decreases. The driver will increase or decrease the voltage as necessary to maintain a constant current.
A type of lamp that produces light inside a transparent, gas-filled tube. Each end of the lamp is sealed with an electrode: one positively-charged (the anode) and the other negatively-charged (the cathode). When the light is switched on, voltage travels between these two electrodes, and fast-moving electrons collide with gas molecules to produce light.
Fluorescent lamps are approximately eight times as efficient as incandescent lamps and last far longer.
Halogen Incandescent Lamp
A type of lamp that produces light by heating a filament inside of a gas-filled bulb. The difference between a halogen incandescent and normal incandescent lamp is a reaction between the halogen gas and evaporated filament material – part of the evaporated material returns to the filament, prolonging the life of the lamp. As a result, incandescent halogen lamps have a considerably longer lifespan than normal incandescent lamps, lasting between 1,000 and 6,000 hours of use.
A type of lamp that produces light by heating a filament inside of a bulb. Only 5% of the energy an incandescent bulb uses goes towards producing light, while the rest produces heat. Because of this, incandescent lamps are largely recognized as the least energy-efficient forms of outdoor lighting.
Since the filament evaporates over time, incandescent bulbs have a relatively short lifespan compared to other types of outdoor lighting, lasting around 1,000 hours of use at most.
Light-Emitting Diode (LED)
A light-emitting diode (LED) is a tiny microchip containing semi-conductive material that produces light by applying a voltage to an electrical junction. Different types of semi-conductive materials produce different colours of light, making it possible to produce a wide range of different colour LEDs. If the chip or cluster of chips is encapsulated in a bulb, it is an LED lamp.
The technical term for a light fixture or light fitting; in other words, the apparatus containing a light source.
A reflector reflects, refracts, absorbs or transmit lights to efficiently direct the light emitted from the bare lamp. It may be a part of the luminaire or the lamp itself, or a component added separately during or after installation. Reflectors are important in the types of outdoor lighting that require precise light control, such as floodlights, spotlights and road lights.
Solid-state lighting is a general term for electronic light sources using solid, semi-conductive material. Light-emitting diodes or LEDs are a type of solid-state lighting.
Lighting Design Principles
Mounting Height (MH)
The vertical distance between the base of a pole and the luminaire; or the ground and the luminaire, in the case of a wall-mounted light.
Light pollution, also known as an uplight, refers to light unnecessarily directed upward into the night sky. Excessive light pollution creates an unnatural glow that masks the view of the sky from the ground. Effective outdoor lighting design uses shields, hoods and other devices can reduce or eliminate skyward lighting.
Light trespass, also known as a backlight, refers to light spilling into unwanted areas like adjacent homes or properties. It can be avoided through careful lighting design, including proper location, mounting and shielding of luminaires. Many cities have by-laws limiting the level of light allowed near property lines to reduce light trespass.
Ask an Outdoor Lighting Installation Expert
When it’s done right, outdoor lighting can boost visibility, increase safety and enhance the night-time environment overall. Poor lighting design, on the other hand, can result in excessive glare, wasted energy and complaints about light pollution and light trespass. Ask an expert on outdoor lighting installation before you embark on your next big lighting project.
