The enclosure on these jelly jar lights contains explosions, sparks, and flashes. These lights are safe to use in NEC Class I, II, and III, Division 1 hazardous locations. Certified to a T4 (275° F) or T5 (212° F) temperature classification, their surface stays cool enough to avoid igniting flammable material. They are also ETL and C-ETL listed to meet safety standards in the United States, Canada, and Mexico. All lights are hardwired and mount with fasteners (not included).

Lights with a built-in LED eliminate the need to swap out bulbs. They’re also more energy efficient and produce less heat than lights with an incandescent bulb. They're rated IP67 for protection against temporary submersion. Lights for incandescent bulbs are rated NEMA 4X for protection from washdowns and dust. Designed to resist corrosion from salt water, they’re also UL marine listed.

Contain explosions, sparks, and flashes—the enclosure on these ceiling lights makes them safe to use in NEC Class I and II, Division 1 hazardous locations. They meet NEC hazardous location temperature classifications, so their surface stays cool enough to avoid igniting hazardous gases or dust. Designed to resist corrosion from salt water, they’re also UL marine listed. All lights have adjustable mounting brackets that can rotate 45° in either direction to direct light where you need it.

Style 1 lights are built for harsh environments, like offshore oil rigs. They have been tested to withstand vibration without breaking or shutting down. The mounting bracket matches standard bolt hole patterns.

Lights with a backup battery shine for at least 90 minutes during a power outage to comply with UL 924.

Safely light up chemical processing plants, mining operations, and other large areas where combustible gases and dust are present. These lights have an explosion-proof housing that contains sparks and flames, so they won’t react to nearby hazards. With a T4 classification, their surface temperature stays below 275° F to avoid igniting flammable substances. Because they’re totally sealed, they also work well in wet, dusty, and corrosive environments—they’re IP and NEMA rated, and UL marine listed.

Mount them to your ceiling or other surface with the included adjustable bracket. The bracket pivots, so you can aim the light where needed. To suspend them from your ceiling, combine a pendant mount and junction box (sold separately).

Light up offshore rigs, coal mines, and other outdoor areas where gas, vapor, or dust could ignite. These lights have an enclosure that contains sparks and explosions, so they won’t react with nearby hazards. The enclosure is also rated IK10, the highest impact rating, so it can withstand heavy blows without breaking. These lights are UL marine listed, with an aluminum housing and stainless steel hardware that resist corrosion from saltwater. They’re also IP66 rated, meaning they are sealed to keep out dust and heavy rain.

Mount these lights to a wall or square pole using the included bracket. The bracket pivots, so you can aim the beam right where you need it.

Safe to use in areas with ignitable concentrations of flammable or combustible gases, vapors, liquids, and dust, these lights are rated NEC Class I, Class II, and Zone 1. Their housing contains fire and sparks, so they don’t ignite what’s in your environment. They’re often used in refineries, mines, and paint booths. Rated IP66, they’re also dust tight and sealed against sprays of water such as those used in washdowns. Since each head weighs less than 2 lbs., they’re easy to hang overhead. Each head has two straps for mounting on pipes, beams, or other surfaces. For more precise control over where the light is directed, add mounting clamps (sold separately). One clamp is required for each head.

These lights come with a standard three-prong plug, so electrical connections must be made outside of the hazardous environment. Alternatively, you can add a hazardous location plug.

Hazardous location environmental ratings indicate where manufacturers have included safety features in products to facilitate their safe use in hazardous environments. Before selecting a product for a hazardous location, ensure it is rated for your environment.
