Properly lighting a large commercial building can be intimidating to many building owners, however, it is essential. Commercial buildings such as professional offices, medical centers, shopping malls and retail stores require a tremendous amount of light for the safety and productivity of the space. From potential visitors seeing the building from the road to guests experiencing the indoor space, lighting plays a key role. There are many factors to consider including indoor and outdoor lighting fixtures, tools and accessories needed to bring the space’s lighting to the next level. Let’s take a look at some popular commercial lighting options.

​INDOOR COMMERCIAL LIGHTING
​HIGH BAY FIXTURES & SENSORS
Light your commercial space with high bay fixtures to maximize efficiency and safety. They produce a ton of light and are ideal for ceilings that are 20 feet or higher. Traditionally, they use high output fluorescent tubes or high intensity discharge (HID) bulbs such as metal halides and high-pressure sodium lamps. However, these technologies have many drawbacks including long warm up times, poor color rendering and high energy costs. Upgrade your high bay fixtures to LED and start saving on your energy bill – either with LED corn cob retrofit bulbs, LED tubes or install fully integrated LED high bay fixtures. Want to save even more on your energy bill? Add a motion sensor to your high bay fixture to control your lighting usage by having them turn on only when needed.
 
TUBES: FLUORESCENT VS LED
Tubes are a popular choice in lighting when it comes to commercial spaces. For those looking to save on energy costs as compared to HID bulbs, fluorescent tubes are a good choice. Offered in different color temperatures, wattages and lengths, fluorescent tubes allow for customization in any space. However, they do have their downfalls when compared to their LED counterpart. LED tubes operate well in cold weather, produce little to no heat, turn on (full brightness) immediately, have an extremely long life and are the most energy-efficient choice on the market. LED tubes are quick and easy to install with plug and play options that work with many instant start ballasts or direct wire options that bypass the ballast, so it’s no longer needed – saving you even more money on replacement ballasts!

​HIGH INTENSITY BULBS: HID VS LED
HID bulbs are the most common choice in lighting technologies for commercial spaces. They are great for tight budgets, as they have low initial costs. However, they do not offer much variety and have a short lifespan. With the rise of LED technology, HID bulbs are being used less and less. LED corn cob bulbs produce a powerful, bright light and are more energy efficient than HID bulbs. They allow for fixtures to be retrofitted quickly and easily – offered in different styles in order to fit any fixture, including shoeboxes, wall packs and high bays. Not only are your standard shapes offered, some LED corn cobs also offer multi-directional lighting with adjustable beam spreads to suit your need.

​TEMPORARY & WORK LIGHTS
Enjoy the freedom of being able to move your light source with you while on the job site! Temporary work lights are ideal for new construction and renovation projects. The portable lighting creates a safe environment that is easy to maintain in the chaos of construction. Temporary work lights can be installed on a job site for the duration of the project and then packed up and installed at the next job. Most temporary lights come with metal guards to protect the durable fixtures and can be hung from the ceiling to provide 360-degree lighting. Others can be set up on the ground using a tripod with a bright light source mounted on top. One of the most popular choices for temporary lights is a temporary light stringer – with multiple sockets for lamps enclosed in cages for protection. Whatever option you choose, all are damp location rated and vibration resistant!

​OUTDOOR COMMERCIAL LIGHTING
​WALL PACKS
Keep your commercial building’s exterior well-lit with a wall pack! Wall pack fixtures will add a level of security to your parking lot – helping your guests feel safe. They’re also great for making your commercial space more visible for after-dark visitors and improving the appeal of your building. Wall pack fixtures have traditionally used inefficient HID bulbs, which rely on reflective lighting since the light produced by an HID bulb is not directional. About 30% of an HID’s light output is “lost” in the fixture and is never projected outward. However, with LED corn cob retrofit bulbs for existing fixtures or fully integrated LED wall pack fixtures, the produced light is directional, and no light output is lost. They also have a considerably longer lifespan than their HID counterparts. 

FLOOD LIGHT FIXTURES
Flood light fixtures offer directional lighting and are commonly used to illuminate parking lots, building facades and landscape elements. Many parking lots have a dim, orange appearance as a result of using HID bulbs. This can give your commercial building an unattractive character – leaving guests feeling unsafe and unwelcome. Consider upgrading to fully integrated LED flood light fixtures instead to allow for a clear, bright white light and eliminate the need for frequent bulb replacements. Plus, you will lower your energy costs! LED flood light fixtures deliver consistent, even light distribution and help to improve the overall appearance of your commercial building’s exterior. When choosing flood lights for your building, consider the area you are looking to highlight. For smaller areas, like gardens or entryways, use a flood light with less lumens and a warmer color temperature (between 3000K-3500K) so you don’t overwhelm guests or create unwanted glare. For larger areas, such as parking lots, use a flood light with a high lumen count and a bright white color temperature (between 4000K-5000K).

​ELECTRICAL TOOLS & INSTALLATION ESSENTIALS
ELECTRICAL & INSTALLATION
From start to finish, you’ll want to make sure all your bases are covered when it comes to electrical and installation essentials. From wall switches and outlets to plugs and connectors, there are many products needed to complete the job. Other items to be aware of include mounting brackets and hanging kits, boxes and panels, wire connectors and sockets. Every toolbox should always have tape, zip ties and nuts and bolts.

​TOOLS
There’s nothing worse than being on the job site without the proper tools. With trusted brands like Garvin, Caddy and Ideal, Lighting Supply has you covered! Lamp changers and your other basic hand tools like screwdrivers, crimpers, pliers and wire strippers are essentials every professional should carry. When working with electrical currents, it's important to have test equipment handy such as light meters, ballast testers, lamp testers and receptacle testers. Lastly, don’t get caught in a dark basement or crawl space without your flashlight! To ensure a working flashlight, always keep a healthy stock of batteries in your tool bag or box – or upgrade to an LED flashlight!

We’ve all experienced the violet glow at arcades, nightclubs and bowling alleys and gave credit to the blacklights. However, “blacklight” is not necessarily the correct term when referring to these fun light bulbs. There are two types of blacklights – blacklight bulbs (BL) and blacklight blue bulbs (BLB) – and they each serve different purposes. The difference between the two bulbs is the amount of ultraviolet light they emit in relation to visible white light. All fluorescent light bulbs have a special phosphor coating, which determines what amount of visible light is seen. Let’s take a look at a few other fundamental differences between the two blacklight bulb types.

 BLACKLIGHT BLUE BULBS
Blacklight blue bulbs have a dark blue, almost black, coating. They use “Wood’s Glass”, a nickel-oxide coated glass, which blocks all visible light – allowing a faint violet glow to escape. When the phosphors are activated it’s known as luminescence and this makes objects near them appear to glow. Blacklight blue bulbs are commonly used for special effects, forensics, dermatology and medical applications, such as phototherapy for newborns with jaundice.

BLACKLIGHT BULBS
Blacklight bulbs appear white in color like a typical fluorescent tube when they're turned off. Turn them on and they glow electric blue through UV transmissive glass. Contrary to their name, blacklight bulbs have a bluer light than blacklight blue bulbs, which appear violet. They are ideal for use in bug zappers since flying insects can see their emitted UV light and are attracted to it.
 
Instead of attracting bugs, which blacklights are good for, yellow bug lights are great for keeping those pesky insects away. Most insects cannot see yellow light so they will not be drawn to it.

​​Still a bit confused? Whether you’re looking to attract insects or set your party aglow, our Customer Service Reps will be able to assist you in choosing the right blacklight (or blacklight blue) bulb. Give them a call at 877.231.2852 or leave a comment below.

Spring is in full effect and the days are getting longer. With more sunlight there’s a greater opportunity to save energy and money on your outdoor lighting – and you don’t even need to lift a hand. Leave the burden of turning on/off lighting to outdoor controls, including dusk to dawn fixtures (with photocells), timers, solar lights and motion sensors. All of these options are simple to use and will put your mind at ease.

DUSK TO DAWN
Perhaps the most hands-off approach, dusk to dawn light fixtures use a photocell to control lighting fixtures. Photocells detect natural light to turn on and off when the sun sets and rises, respectively. This option is a big energy saver as there’s no unnecessary usage. They also account for seasonal shifts in daylight as they will automatically conform to longer days and shorter nights – unlike a timer that must be manually adjusted. Photocells can easily be added to most fixtures to convert them into dusk to dawn fixtures.

TIMERS
While timers do need to be manually adjusted based on differing daylight hours, they are still a fantastic tool to control your lighting – allowing you to set the timer to the exact minute you want your lights to be active. They are especially beneficial during the spring and summer when paired with outdoor string lights on your deck or patio.​

SOLAR LIGHTS
Solar lights are a “set it and forget it” type of lighting. They require little to no maintenance and typically use LED lights, making them even more energy efficient. Solar lights work by using a solar cell that converts sunlight into an electrical current. The sunlight is stored in the fixture during the day, then in the evening, a photoreceptor senses the darkness and turns on the light. The solar cell stops working and gets weaker and eventually turns the light off. The process of collecting sunlight then begins again the next morning.

MOTION DETECTOR
Do bumps in the night keep you on edge? You can relax and take comfort in knowing that your motion detector light fixtures will turn on when they sense movement nearby. Motion-activated fixtures have sensors that detect infrared waves, or heat waves that are emitted by moving objects. Install them on your garage, by entry ways or directed towards your driveway for peace of mind.

Whether you spend your spring and summer nights outside on the patio, or just want added home security, Lighting Supply will have the best outdoor lighting controls for your application. We carry hundreds of options and our Customer Service department is standing by to answer any questions. Give them a call Monday through Friday from 7:00 am – 6:00 pm ET or leave a comment below!

With LED lighting becoming the norm, more people are becoming aware of the benefits of upgrading outdated lighting. However, this does not mean the switch is always straight-forward; there’s room for error. To avoid these issues, check out these common mistakes first-time LED users tend to make.

​Assuming your fixture accepts LED bulbs.
Think of any light bulb imaginable; chances are there’s an LED replacement. There are numerous terms to describe the usability of these products. You may see terms like “ballast compatible”, “plug and play”, "instant fit" or “direct wire”. Ballast compatible, plug and play and instant fit all essentially mean the same – remove your current bulb and simply replace it with its LED counterpart. If you have a direct wire LED bulb, you will need to remove the ballast, or power supply, and hard-wire the LED bulb and socket. Always read the manufacturer’s specifications and your fixture’s guidelines to ensure the proper use and acceptance.

​Not taking light output into account.
When replacing standard light bulbs, we are accustomed to comparing the wattage and finding one that matches the light output we are looking for. With LED bulbs, the comparison is not always so simple. To get a more accurate LED replacement, you must check the lumen output, or the amount of visible light a bulb emits. For example, a 60 watt A19 bulb – think the standard light bulb in your home – produces about 800 lumens. Its LED counterpart that produces the same number of lumens will use, on average, only 10 watts. Learn more about lumen comparison here.

​Choosing the wrong color temperature.
Identifying the right color temperature, measured in Kelvin, is important when lighting a room. Color temperature has nothing to do with the actual heat a bulb produces, but rather the color tone of the bulb – ranging from warm to cool to daylight. For some bulbs, it’s simple to figure out their color temperature as it is stamped on the bulb itself. However, some will not be so obvious. For example, if you are replacing an incandescent bulb with an LED and want it to emit the same warmness, choose a bulb with a Kelvin rating of 2200K-2700K. For halogen bulbs, choose a color temperature around 3000K-3200K, as most halogens have a warm color tone.

​Not considering the light pattern the bulb will produce.
When choosing an LED replacement bulb, be sure to check the beam angle and light pattern. Not all light bulbs are omni-directional; meaning the light shines in all directions. Also, not all bulbs will project the same light pattern you’re aiming for. For example, an A19 bulb is omni-directional and is great for general lighting purposes. Whereas a PAR-shaped bulb is highly directional and is ideal for highlighting landscape elements in front of your home. Bulbs can also have different beam spreads that can vary from narrow to wide, depending on their application.
 
Not using a compatible dimmer.
Incandescent and halogen bulbs are fundamentally dimmable with any dimmer switch as long as the voltage and wattage requirements are met. However, not all dimmer switches are compatible with LED bulbs and not all LED bulbs are dimmable. If you experience flickering, strobing, unresponsive bulbs, or bulbs that turn off before reaching the lowest dimming range, it’s likely that your dimmer is not compatible with your LED bulb. Ensure that you are using an LED dimmer so the bulbs function properly.
 
Not doing your research.
With the demand for LED products on a steep incline, it seems there are new companies popping up each day with the “latest and greatest” technology. However, many of these products are made in foreign countries with no direct customer service – making returns of damaged or defective products nearly impossible. Many of these new companies are not reputable and may be producing low quality products that will fail quickly. Research the brands and companies you are ordering from and be aware of their history, return policy, warranties and customer reviews.

With so many LED options on the market, it can be hard to make the right decision. Let us give you a hand. Lighting Supply been around for 35 years and we're focused on strong customer support and selling trusted brands.

When you start to look up and pay attention to the lighting around you, you’ll notice recessed lights are a very popular choice – residentially and commercially. Homes can use dozens of these fixtures; commercially, there could be hundreds. Recessed lighting is flush with the ceiling where the housing is hidden. These fixtures are comprised of three parts: the housing, trim and bulb. This trim is the decorative, finished part of the fixture that we see, and the housing is installed inside the opening in the ceiling. There are many different bulbs that be used in recessed lighting fixtures including incandescent, compact fluorescent (CFL) and LED.
 
Maintaining those recessed lights can be daunting and burdensome, not to mention the high energy costs if you’re still using incandescent bulbs. Even if you are using LED bulbs, they only have an average life of about 25,000 hours. Upgrade your recessed lighting with an LED retrofit kit, doubling the LED life with an average life of about 50,000 hours. These fixtures have an integrated driver, or power supply, and trim. The LED retrofit unit fits right into the existing housing. Install a recessed retrofit kit in a fraction of the time it takes to mount a conventional fixture. 

Lighting Supply offers many reputable brands that are carrying their own lines of recessed retrofit kits, including TCP and FEIT. These kits come in different color temperatures, sizes and styles such as the standard flush look and gimbal – a lens that can be adjusted to highlight features of your home or business. There are even wet location rated options so you can upgrade the lights in your bathroom and shower.

Take a step towards the future of farming with horticulture lighting. Grow crops year round with tailor-made lighting systems where outdoor conditions are mimicked for optimal growth. Choose a horizontal farm or a vertical farm system. Horizontal farms are what most people are familiar with - all plants on the ground level. Vertical farms, however, are growing in popularity due to their space-saving benefits. They allow for more plants to be packed closer together and stacked on top of each other on shelving units; maximizing the grow. When plants are grown in a controlled environment, color spectrum, temperature and light intensity can be regulated so crops can thrive with faster growth, bigger harvests and higher quality plants. Indoor farming can be difficult and there is lots of science that comes into play.
 
Here’s a quick overview of the grow cycle

The mother plant is where the cycle begins. Typically, crops are not cultivated starting with seeds. Rather, a clone plant is grown by cutting an off-shoot from a branch of the mother plant and then dipped into rooting gel. After about 7-12 days, roots begin to develop on the clone plant. The plants then go through the vegetative and flowering/fruiting stages. In the flowering stage, lights are on for about 12 hours and off for about 12 hours per day. During the 12-hour dark cycle, it’s important that there is absolutely no light present in the room. Lastly, the plants are harvested.
 
How does your light bulb choice affect the growth?
 
There is still some debate about which lighting applications are ideal and which type of lighting is needed to obtain the best responses in plant growth. Green plants need light for photosynthesis to take place. Photosynthesis is the process by which green plants use sunlight to synthesize foods from carbon dioxide and water. Light exposure in greenhouses can be limited so supplemental lighting is needed to grow plants all year long. The three types of bulbs that are most commonly used are High Pressure Sodium, Metal Halide and LED.
 
High Pressure Sodium
High Pressure Sodium (HPS) bulbs are used during the vegetative and reproductive cycles. They may also be used as supplemental light for full-spectrum lighting. HPS bulbs emit a yellow-red visible light. The red spectrum may induce a greater flowering and fruiting response in plants and may cause the plants to grow more rapidly. In a greenhouse, plants receive light from blue spectrum naturally, so HPS bulbs are often used as supplemental lighting so the plants also receive light from the red spectrum.
 
Metal Halide
Metal Halide and HPS lamps have a color spectrum similar to the sun’s rays, which make them great for growing plants. Metal Halide bulbs are commonly used in the vegetative cycle since they radiate blue and ultraviolet radiation. Blue spectrum lighting may initiate a better vegetative response in plants.
 
LED; Light Emitting Diode
The white light from LED bulbs provide a full-spectrum of light designed to emulate natural light with a balanced spectrum of red, blue and green. LEDs are a great choice for all grow operations. The industry standard for the vegetative cycle is to use 400W HID bulbs. Even in a small grow room, energy costs can be astronomical. LED bulbs are great not only for lowering your energy costs, but they also produce little to no heat. Even though they produce little heat, LED grow lights should be kept at least 12” away from plants to prevent leaf burn.

​Have you noticed how some light bulbs appear more yellow or orange and others a bright white? This can be explained by what’s known in the lighting industry as color temperature. Color temperature refers to how warm or cool a bulb’s color appears. Try not to get caught up on the word “temperature” since this has nothing to do with the actual heat the bulb produces. Color temperature is measured in Kelvin (k) – a thermodynamic temperature. The lower the Kelvin rating, the warmer the bulb will appear; the higher the rating, the cooler, and seemingly brighter, the bulb.
 
Color temperatures range from warm white to daylight; and even full spectrum beyond that. When you imagine your typical household incandescent bulb, you’ll think of the warm glow it emits. Incandescent bulbs have a color temperature of around 2700K, or warm white.  When most people think of LED bulbs, they picture a bright white; or daylight (5000K). However, it’s a common misconception that LED bulbs are only offered in this bright white, which most people find too harsh or blue for use in common areas of homes. CFL and LED bulbs can actually come very close to the warm color of incandescent bulbs, while still offering a wide range of other color temperature options.
 
Let’s take a look at the different color temperatures and their best uses.

​WARM WHITE
Warm white bulbs will have a Kelvin temperature of 2700K; again, picture any incandescent bulb in your home. These bulbs promote a warm and cozy environment and are best utilized in restaurants, hotel lobbies and homes. Quickly growing in popularity, LED Edison bulbs mimic the look and warmth of vintage incandescent bulbs with unique filament designs. Try them in your living room or bedroom!

​SOFT WHITE
Soft white bulbs have a Kelvin temperature of 3000K. They will have a slightly more white appearance than its warm white counterpart. Use these in libraries, office areas and retail stores to create an intimate and personal space. This color temperature is also great for homes and is interchangeable with warm white color tones.

​NEUTRAL WHITE
Neutral white bulbs have a Kelvin temperature of 3500K. They have a mostly white appearance with a subtle yellow tint. This color temperature is ideal for public reception areas, showrooms, bookstores and office areas where you want it to feel friendly, inviting and non-threatening. 

​COOL WHITE
Cool white bulbs have a Kelvin temperature of 4000K-4200K. Cool white bulbs have the appearance of pure white and make a room feel neat, clean and efficient. They are commonly used in conference rooms, classrooms and hospitals. Cool white bulbs are known to help with concentration in classrooms and productivity at the work place. Studies show it reduces the brain’s production of melatonin, a hormone that plays a role in our sleep, reducing daytime sleepiness.

​DAYLIGHT
Daylight bulbs have a Kelvin temperature of 5000K and higher. Museums, jewelry stores and print shops commonly use daylight bulbs because they are great for exacting coloration. They are also very bright and promote alertness, making them great for use in medical exam rooms. You can also use them in warehouses because, similarly to cool white bulbs, they also encourage higher productivity and ensure your employees can see well – cutting back on workplace injuries.

FULL SPECTRUM
Full spectrum bulbs have a color temperature of 5700K and higher. Full spectrum light most closely simulates the light we receive from the sun. Humans rely on sunlight for not only Vitamin D, but it’s also thought to produce serotonin, a hormone associated with happiness and focus. For those who aren’t exposed to the sun very often, it can often leave us feeling down in the dumps – especially in the wintertime. Full spectrum lighting helps alleviate these feelings and has shown to boost moods and a feeling of calmness.
 
When deciding which color temperature is best for you, consider what feeling you are trying to evoke in each room. Do you want all of your rooms to have the same lighting, or are you going to base the lighting in each room on a preferred ambiance and tasks completed in those rooms? Many people prefer a brighter light in the bathroom or at a vanity where make-up is applied, whereas they may want a warmer light in their living room or bedroom for relaxing. This is an individual decision based on preference.

Trying to determine which light bulb you need can send your head spinning. It can be very confusing with so many different shapes and sizes to choose from. You may even be questioning why there is such a wide variety of choices. Light fixtures are generally specific about which light bulb can be used so it’s important to know exactly what you are looking for. Luckily, of all the shapes offered, there are only eight that you’ll typically need to worry about in any given home.
 
MOST COMMON HOUSEHOLD BULBS
​

​Arbitrary (A): When you picture a light bulb, you’re likely thinking of an arbitrary shaped light bulb. It’s the most common and well-known bulb shape. You can find them in table lamps, wall sconces, ceiling fixtures and more.

​Bulged Reflector (BR): BR bulbs are known for their conical shape and rounded lens. They are most often used in floodlight fixtures and recessed downlights.

​Candle/Candelabra (C): Candelabra light bulbs are shaped just like, you guessed it, candles! They can have a teardrop, torpedo or flame shape and are used in chandeliers and accent lighting.

​Globe (G): Globe light bulbs are decorative and round in shape. They are commonly seen in bathroom vanity fixtures, ceiling fans and other decorative fixtures.

​Multifaceted Reflector (MR): MR bulbs provide a polished look in your track lighting systems. They are offered in different flood degrees – spot, narrow, and flood – and are used to highlight artwork, architectural elements, and task areas like your kitchen island.

​Parabolic Aluminized Reflector (PAR): PAR bulbs are very similar to BR in shape but are more robust. They are used in your outdoor floodlights and landscape fixtures. Although similar in shape, compared to BR bulbs which provide a more general area light, PAR bulb beams are more focused.

​Tubes (T): The three most common fluorescent tubes are T5, T8 and T12. Tubes are generally used in undercabinet fixtures, laundry rooms, garages and basements. Fluorescent tubes require an additional power source, or a ballast.

​Twist: CFLs, or compact fluorescent, are described as a twist. These bulbs are a popular choice for replacing A-shaped incandescent bulbs as they are more energy efficient. CFL bulbs are also commonly referred to as spiral shaped.

​Now that we’ve established the different shapes to look for, it’s time to address the varying sizes of light bulbs. With each shape offered, there are multiple sizes to choose from. The size of a light bulb is measured in eighths of an inch at the widest point of the bulb – or the diameter. A bulb’s code is created using a letter followed by the measurement. For example, an A19 bulb is arbitrary in shape and is 19/8ths of an inch in diameter. A-shaped bulbs come in a few different sizes including A15, A19, A21 and A23.

​When in doubt, try to bring your existing bulb with you to the store for reference. If you no longer have the bulb, try to get as much information from the fixture itself to help narrow down your choices. Important information to note would be the max wattage your fixture can handle, the voltage and the base type.
