Operators dealing with coal or grain dust will find Larson Electronics Magnalight EPL-ACH-HPS150W explosion proof high pressure sodium light useful in penetrating coal, grain and other dusts.

Larson Electronics’ announced the addition of a Class 2 Division 1 light that is suitable for illuminating areas with airborne dust. While metal halide and incandescent based lights are effective in illuminating most areas, lighting up and area laden with dust requires high pressure sodium fixtures. This is particularly true of combustible coke and coal dust, which is not only dark in color, absorbing light, but also has lower ignition temperatures according to the National Electrical Code’s properties for Group F dusts. However, this explosion proof high pressure sodium light is also effective for grain and sugar dusts which fall into Group G. Certified as a UL 844 Class II Division 1 and Class 1 Division 2 light, this 150 watt high pressure sodium light can be used with flammable vapors in Groups C and D and explosive dusts in Groups E, F and G. Equipped with a trunnion mount and factory sealed cord, the EPL-ACH-HPS150W explosion proof high pressure sodium light can be permanently mounted so that the beam is positioned where the operator most needs the illumination.

“A 150 watt high pressure sodium light outperforms a hazardous location 1000 watt metal halide light when dealing with dusts,” said Rob Bresnahan with Larson Electronics. “Especially when dealing with light absorbing dusts like coke and coal, high pressure sodium lights will better penetrate the dust cloud, while metal halide light is generally absorbed and ineffective. The properties of a material and the surrounding environment have a big effect on how effective a light is. Metal halide and LED lighting are very effective in general illumination or long distance spotlight applications, but operators dealing with dusts will find more success with high pressure sodium. Assuming the operator is dealing with a Division 1 area, then 150 watts of high pressure sodium is going to be the limit, given the lower ignition temperatures associated with dusts. With a deep reflector, the EPL-ACH-HPS150W explosion proof high pressure sodium light concentrates that light for good punch power in silos and other storage areas.”

Larson Electronics’ offers a wide range of explosion proof lighting with UL certified 844 and 783 Class 1 and Class II ratings for hazardous locations. With options ranging from explosion proof drop lights to paint spray booth rated fluorescent lighting, Magnalight explosion proof lights are applicable to commercial, industrial and military applications.
