Explosion proof lighting is a code requirement in environments where flammable gases, vapors, dusts, or fibers may be present in concentrations capable of ignition. Oil refineries, chemical processing plants, petrochemical storage areas, grain handling facilities, paint spray booths, and certain pharmaceutical manufacturing spaces all fall under NEC Article 500 hazardous location classifications that mandate approved explosion-proof or explosion-resistant luminaires.

RelightDepot carries Class I Division 1 and Division 2, and Class II Division 1 and Division 2 LED fixtures for hazardous location applications. LED technology has largely replaced the HID sources previously standard in these environments, offering significant energy reduction, longer service life, and elimination of the warm-up delays that can be a productivity and safety concern in process environments. Fixture housings are cast aluminum or stainless steel with threaded conduit entries and gasketed lenses to contain any arc or spark.

When ordering, confirm the NEC Division and Group classification for the installation location, as fixtures are listed for specific groups based on the gas or dust present. Our product specifications include Division, Group, and temperature class ratings for each fixture.
