LEDs are the up and coming lighting technology. Each successive generation is more energy efficient than then last. Today LEDs last up to 10 times longer than compact fluorescents and far longer than typical incandescent bulbs. The latest LED (light emitting diode) light bulbs produce about the same amount of light per watt as compact fluorescent bulbs (CFLs). LEDs can be found in luminaires (light fixtures) and even retrofit lamps (bulbs).

A light-emitting diode (LED) is a semiconductor diode that radiates light (electroluminescence) when current passes through it in the forward direction. Electrons move though semiconductor medium and “fall into” other energy levels during their transit of the p-n junction. When these electrons make a transition to a lower energy level, they give off a photon of light. This photon may be in the infrared region or just about anywhere across the visible spectrum up to and into ultraviolet.

Because of the low power requirement for LEDs, using solar panels becomes more practical and less expensive than running an electric line or using a generator for lighting. There are other differences beyond life and energy savings. Unlike incandescent bulbs and CFLs, which splash light in all directions, LED bulbs are directional. LEDs drive their light in one direction, so that you have light exactly where you want it. This directional lighting equals savings in yet another fashion. LEDs don’t waste light (energy) on areas you don’t need illuminated, which is also why they are perfect task lights.

Since LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken. Because they are solid, LED bulbs hold up well to jarring and bumping. These bulbs do not cause heat build-up; LEDs produce 3.4 btu’s/hour, compared to 85 for incandescent bulbs. Last, no mercury is used in the manufacturing of LEDs, and they are more efficient. LED light bulbs use only 2-10 watts of electricity (1/3rd to 1/30th of Incandescent or CFL).

New Fixtures With T8 LED Tube Lights Introduced by Access Fixtures

WORCESTER, Mass., Jan. 27, 2015 /PRNewswire/ — Access Fixtures has expanded its LED product line to include T8 LED Vapor Tight High Bays and T8 LED Wrap Around Fixtures. Previously an industry standard with T8 fluorescent lamps, the fixtures are now available with T8 LED retrofit tube lights instead of fluorescent tubes to save energy and reduce maintenance. Able to operate on 120v to 277v, the fixtures are ideal for use in warehouses, retail spaces, offices, and other industrial and commercial applications. The vapor-tight fixtures are able to be used in applications where dust or moisture is present. “The introduction of these two fixtures creates a very low-cost LED option for vapor tight and basic wrap around fixtures,” said Access Fixtures CEO, Steven Rothschild. “Instead of buying T8 fluorescent fixtures for commercial or industrial spaces, property managers can now choose LED for close to the same price, while getting the energy savings, low maintenance and high CRI supplied by T8 LED tube lights.” These new fixtures are built to work with T8 LED tube lamps. T8 LED tube lights are a cost-effective and energy-efficient alternative to T8 and T12 lamps. Manufactured with integral drivers, the luminaires do not require a ballast or driver. The T8 LED tube lights operate on 120 to 277 line voltage, have twice the life of T8 linear fluorescent lamps, emit 10% higher lumens per watt as compared to T8 fluorescent, and direct the light down to where the light is needed. The T8 LED tube lamps are rated LM70 at 50,000 hours of use. Furthermore, the LED tube lights have a CRI of 80+...

New T8 LED Retrofit Tube Lights Introduced by Access Fixtures

WORCESTER, Mass., Jan. 13, 2015 /PRNewswire/ — Access Fixtures, a leader in commercial and sports lighting, has announced new T8 LED retrofit tube lights that are designed to perform efficiently in place of fluorescent lamps. The long-lasting, energy-efficient T8 LED tube lights incorporate integral drivers, eliminating failure-prone fluorescent ballasts, and simplifying T8 lighting systems. The T8 LED tube lights connect directly to line voltage for easy installation. “The cost of manufacturing T8 LED retrofit tube lights was high and they required a ballast, so our lighting specialists didn’t see the value. Consequently, we didn’t sell them,” said Access Fixtures CEO, Steven Rothschild. “Now, Access Fixtures can sell them for less than $15 per lamp and users do not need a ballast. T8 LED retrofit tube lamps are a cost-effective and energy-efficient alternative to T8 and T12 fluorescent lamps.” Rated for 35,000 hours, T8 LED retrofit tube lamps have an integrated driver and do not require a ballast. Ballasts typically last for 50,000 hours. For LED retrofit lamps that require a ballast, this means using an existing ballast or purchasing a new ballast. An existing ballast typically fails before the LED retrofit, causing maintenance and cost, while installing new ballasts adds significant expense negating the value of the T8 LED retrofit lamp. Using only 19 watts, the T8 LED retrofit tube lamps provide high efficiency over 100 lumens per watt, have CRI of 80+, and do not contain mercury. The T8 LED tube lights are available in two-foot and four-foot lengths, and two color temperatures, 4100k and 5000k. They are designed to replace T12 and T8 fluorescent lamps. The lights...

The Answer For Horse Stables – T5HO Vapor Tight Fixtures

A racetrack in Maryland contacted Access Fixtures looking to install fixtures in a new building where horses will be stabled. Horse stables generate dust from hay that the horses eat, wood shavings which are used for bedding, and from the open air ventilation which inherently creates a buildup of dust and dirt. To maintain suitable and efficient light output, the fixtures need to be periodically hosed down to prevent dust and dirt from collecting on the fixtures. An Access Fixtures lighting specialist recommended a 6 Lamp T5HO Vapor Tight High Bay Fixture with an emergency backup ballast. Access Fixtures’ rugged T5HO vapor-tight high bay fixtures are engineered to withstand this type of environment. The fixture is fully gasketed to provide total protection from dust and moisture penetration, which enables the luminaire to be hosed down as needed. It also features stainless steel hardware for maximum durability. The county’s electrical code requires the fixtures to be NEMA 3R rated. The customer had originally chosen another company to provide the T5HO luminaires, but then it turned out they could not meet the NEMA-rated standards for the fixture. Fortunately for the stable, they found Access Fixtures’ 6-lamp T5 vapor-tight high bay fixture is rated NEMA 4x, exceeding the county code’s requirements. This type of enclosure is watertight, extremely corrosion-resistant, and is often used on ship docks, dairies, and breweries. Recommending T5HO linear fluorescent lighting was an obvious choice. T5HO is energy efficient and cost effective. T5HO luminaires exclusively use electronic ballasts that are lighter weight and smaller size than electromagnetic ballasts, increase system efficiency because they use less power themselves, and operate...

New Trampoline Sports Facility to be Illuminated with T5HO Lighting

Access Fixtures lighting specialists received a call from a new business, Launch Trampoline Park. Launch Trampoline Park was looking for T5HO lighting to light their new location in Watertown, Mass. The building where this business will be housed is 37,000 square feet in size and in need of ample light. Inside this trampoline park there will be many trampolines as well as Xtreme Dodge Ball tournaments and a free fall area. With this amount of activity taking place, the lighting is important. Guests attending the park need to feel the facility is clean and safe. They also need to see obstructions and other people before bouncing from one spot to another. Working with Access Fixtures lighting specialists, Launch Trampoline Park chose 6-lamp T5HO linear fluorescent fixtures equipped with GE ballasts and a lens. The lens will help protect the lamps from being hit by flying objects as well as protect visitors if a lamp should ever break. The high output lamps being used enabled the facility designers to achieve an average of 60 foot candles, while being energy efficient. The new trampoline park building is still being renovated and is expected to open in December. The Access Fixtures team hopes to visit the park to support a local business while checking out the lighting...

I have T8 luminaires in my retail store and want to reduce energy use. Should I replace them with T5 or T5HO?

A property manager contacted Access Fixtures with a goal to save energy in his retail store. He wanted to know if upgrading T8 linear fluorescent luminaires to T5 or T5HO luminaires would accomplish this. Although T5 is a newer technology, high-performance T8 lamps and ballasts remain slightly more efficient than T5. T8s can have the highest energy efficiency out of all linear fluorescent lamps. It this case it would depend on the efficiency of the ballasts presently installed. If the ballasts are an older less efficient ballast the property owner might save money by changing the ballast to a Consortium for Energy Efficiency (CEE) approved ballast. This may save some energy. The second option that could be taken along with changing the ballast is to go to lower wattage T8 lamps. A 25w T8 lamp on an efficient ballast will generates up to 100 lumens per watt. To be sure, the situation requires more analysis including desired light levels, CRI, and the cost of electricity. For more information on how to choose the right linear fluorescent lamps, ballasts and luminaire for your lighting project, visit our new fluorescent lighting learn page or contact an Access Fixtures lighting...

Food Processing Facilities Gain LED Lighting Option with NSF Sanitation Certified T8 LEDs

With their newly acquired NSF sanitation certification, Forest Lighting’s LED products can now provide long-term energy savings to the food processing industry! Forest Lighting, the USA branch of worldwide LED manufacturer MLS distributed by Access Fixtures, has officially received certification for their T8 LED tube lamps by the National Sanitation Foundation (NSF). The certification falls under the requirements of “NSF/ANSI Standard 2: Food Equipment.” Forest Lighting’s T8 LED tube lamps from Access Fixtures can now be used in the food processing  industry, specifically automated food processing facilities, kitchens, and serving areas. Sanitation Certification: What Does It Mean? The NSF sanitation certification requires that all materials that could come into contact with food materials must be in line with FDA standards. There are three categories of certification for equipment intended for use in the food industry: Non-Food Zone, Splash Zone, and Food Zone. How a piece of equipment is certified is determined by two factors: its proximity to food products and whether or not it will be affected by food sanitation processes. If the latter is an issue, lighting fixtures must be able to withstand high-pressure washing and cannot pose any risk of chipping or dripping into food materials. Clean Lighting for the Food Industry Few industries have more stringent requirements than the food industry. To meet regulations and achieve the necessary light levels, food processing facility managers have been paying top dollar for traditional, high-powered luminaires rated for wet locations. The quality of light is just as important as the safety of the fixture. A light source’s ability to accurately represent the color of an object is referred to...

How to Rewire T12 or T8 Fluorescent Fixtures for T8 LED Lamps

So, you’re ready to upgrade your fluorescent lighting to T8 LED! Don’t panic; rewiring a T12 fluorescent luminaire or T8 fluorescent luminaire is simpler than you think. Most locations require the work to be completed by a licensed electrician, so be sure to check with local regulations to determine the safest way to proceed. For the DIY crowd, the following guide outlines how to rewire a T12 or T8 fluorescent luminaire for T8 LED lamps with an internal driver. T8 LED Installation Instructions Confirm that the power source to the luminaire is between 120v and 277v. Shut off the power going to the light fixture. Make sure the switch that controls the power to the luminaire does not have a dimmer. Disconnect the power supply to the fluorescent ballast. Remove the ballast and starter, if applicable, from the existing fixture. Remove the existing lamp holders or sockets (these are also commonly known as tombstones). Install the non-shunted lamp holders in place of the existing lamp holders. (“Non-shunted” means that there is no connection between the the contacts at the socket. See photo for how your lamp holders should and should not look.) Using shunted tombstones can fry the socket and damage the LED lamp. Mark the LIVE END of the fixture using either a permanent marker or stickers. Note that the lamp holders on the other end will not be wired to anything. Wire the positive lead to one of the leads on the side marked “LIVE END.” Wire the negative lead to the other lead on the LIVE END lamp holder. Be sure to secure all connections with...

Fluorescent Lamp Sales Decline Due to Regulation and Technology

Overall sales of fluorescent lamps are declining due to regulation and changing technology. While energy regulations have eliminated product offerings, linear fluorescent lamps are also facing competition from LED tube lamps, or TLEDs. Once considered inadvisable due to high cost and complicated installation requirements, TLEDs have become significantly more commonplace as prices decrease and products are developed with better compatibility to existing fixtures. Strict regulation has continued to reduce sales of T12 lamps, showing a year-over-year decrease of 39.5% and maintaining the downward trend exhibited throughout the past five quarters. As T12 lamps are driven into obsolescence by the 2012 legislation, TLED alternatives are gaining popularity for their high energy efficiency. Compared to a T12 lamp and ballast, TLEDs generate double the lumens per watt, last three times as long, deliver 13% more light per tube, and reduce energy use by nearly 40%. T8 lamps suffered a similar—though less severe—sales decline, dropping by 21.7%. T8 lamps are more efficient than T12, offering improvements in color characteristics while the reduced diameter lessens the amount of light trapped within the luminaire. But again, when placed side-by-side the T8 LEDs exhibit 30% more efficiency than their linear fluorescent counterparts and contain no mercury. The year-over-year downturn for T5 lamps was by far the least extreme, showing a decrease of 14.8%. T5 lamps and specifically T5HO lamps are energy efficient and work extremely well in high bay applications. T5HO luminaires increase system efficiency by using less power themselves and also through the elimination of strobe and ballast hum by operating at very high frequencies. T5H0 uses electronic ballasts exclusively, which are lighter in...
