Explosion proof lights are sealed LED fixtures rated to operate safely in hazardous locations where flammable gas, vapor, or combustible dust is present. This category covers explosion proof high bays, flood lights, and linear fixtures for Class I and Class II Division 1 and 2 environments.
An explosion proof light does not prevent an explosion; it contains any spark or heat inside a rugged housing so it cannot ignite the atmosphere around it. These fixtures are specified by hazardous area classification, so the first job is matching the fixture rating to the Class, Division, and Group of the space. The three form factors in this category cover most jobs: Explosion Proof High Bays for tall process areas, Explosion Proof Flood Lights for aiming light across a yard or tank farm, and Linear Explosion Proof Lights for walkways and low ceilings. For general plant areas outside the classified zone, step back up to Industrial Lighting.
Hazardous location ratings decide which fixture is legal to install. Confirm the area classification with your electrical engineer before ordering, then match it to the fixture rating below.
| Classification | Hazard Present | Typical Fixture | Common Areas |
|---|---|---|---|
| Class I Div 1 and 2 | Flammable gases or vapors | Flood and high bay | Refineries, fuel depots, paint booths |
| Class II Div 1 and 2 | Combustible dust | Sealed high bay | Grain handling, flour, coal, metal dust |
| Class III | Ignitable fibers | Enclosed linear | Textile mills, woodworking |
| Wet or washdown | Water and corrosion | Sealed IP66 linear | Walkways, tunnels, wash areas |
Size output the same way you would any industrial fixture: by mounting height and target footcandles. A sealed explosion proof high bay at 20 to 30 ft typically runs 100 to 200W and replaces a 250 to 400W metal halide unit. The spec that is unique to hazardous areas is the T code (temperature code), which caps the fixture surface temperature so it stays below the ignition point of the gas or dust present. Match or exceed the T code your area requires, and confirm the ambient temperature rating if the space runs hot.
Explosion proof fixtures use thick cast housings, heat tempered glass lenses, and sealed entries so the enclosure can hold pressure. Most accept standard threaded conduit, and many offer pendant, ceiling, wall, or stanchion mounts. Look for a copper free aluminum housing in areas with corrosive vapor, and plan the conduit seal fittings into the install, since those are what keep the rating intact at the fixture.
