Explosion Proof LED Light

Larson Electronics Magnalight announced the production ready release of the EPL-48-2L-LED, a fully integrated, explosion proof LED light for hazardous location areas. Rated UL 844 Class 1 Division 1 and Class II Division 1, this LED light fixture is also UL listed for use in wet areas and paint spray booth operations. Equipped with two 24 watt LED T-series style bulbs, this fixture is an LED powered alternative to the popular EPL-48-2L explosion proof fluorescent light fixture. Absent is the standard ballast box assembly, since the T-series style LED light bulbs run directly off high or low voltage power. The EPL-48-2L-LED can run on voltages ranging from 120 volts to 277 volts and low voltage models can run on 12 and 24 volts AC or DC. This Class 1 Division 1 fluorescent light alternative produces 4100 lumens and is available in 4500K, 5600K and 6500K color ranges. The T-series style LED bulbs have the same pin configuration as a standard T8 fluorescent bulb and are made using the new Samsung LEDs which provide high lumen output efficiency while operating at lower temperatures than the fluorescent T-series bulbs they replace. Rated at 50,000 hours of life, these LED T-series tubes offer more than 2 times the longevity of comparable T-series fluorescent bulbs while drawing less current.

Rob Bresnahan, President of Larson Electronics, explained, “We are looking to offer our customers hazardous location LED lighting that will offer economical advantages. Obviously longevity offers savings, because you are not replacing the bulbs as frequently as you would with fluorescent bulbs. However, you can buy a lot of fluorescent bulbs for the cost of the LED bulbs. LED bulbs are still significantly more expensive than incandescent or fluorescent bulbs. The gap in bulb longevity is much greater with incandescent lights than it is with fluorescents. However, the Magnalight T-series LED tubes have lumen output on par with the T8 32 watt fluorescent. So, there is legitimate 25% savings in electricity with twice the bulb life. Depending on usage, there could be real savings here.

However, the replacement cost on a T8 bulb is less than $10 and the LED is running north of $50 right now. So, additional savings are going to come from the relamping process.    Relamping explosion proof fixtures takes more time that relamping a normal ‘drop-in’ fluorescent light found in a normal office environment. You don’t just swing open door and twist some new bulbs into place. All Class 1 Division 1 and Class II Division 1 fluorescent lights are relamped from one end to maintain the seals necessary to achieve the safety ratings. Fixture placement may require man lifts, ladders or other aids in reaching the fixture, especially if they installed in an aerospace industry style paint spray booth or on an oil rig in transit. As such, relamping explosion proof lighting may result in additional costs and safety concerns associated with changing the bulbs. This especially true for 24 hour operations, where production and/or man hours have to be diverted from revenue generating operations to maintenance and repair. So, we think that LED T-series style offers legitimate savings for operators that have hazardous location lighting requirements. “

Rob continued, “Shortly, you will see the LED bulb option available for our explosion proof hand lamps, drop lights, etc. since there are also some clear advantages in cost, since the incandescent bulbs are particularly short lived and more susceptible to vibration. Moreover, operators replacing bulbs in the field lose time and have to pay close attention to all the gaskets and brackets needed for re-assembly to maintain the UL 783 safety ratings. One of the biggest advantages to LED bulbs for the industrial arena is that they are vibration proof. Incandescent bulbs, even rough service bulbs, have a filament that may break when the light is dropped. The fluorescents are more resilient, but high vibration environments, like oil rigs will take their toll on those bulbs too. LEDs are impervious to vibration and we have developed a lot of techniques for dampening vibration effects on the components that drive the LEDs as well. Our LED bulbs are unaffected by vibration. You can drop them endlessly and the bulbs will continue to function normally. “

Larson Electronics LLC manufactures and sells a wide range of hazardous location lighting and air handling equipment.
