Bring light to explosion-prone work areas. Rated NEC Class I, these lights are safe to use in areas with ignitable concentrations of flammable or combustible gases, vapors, and liquids. The housing of these lights contains fire and sparks, so they don’t ignite what’s in your environment. They’re often used in mines and underground drilling. All also meet NEMA 4X, meaning they withstand spraying liquid, resist corrosion, and keep out dust. Use the hook to hang them where you need them. 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.

Safely light up large spaces where combustible gases and dust are normally present. Rated NEC Class I and II, these lights have a housing that contains any sparks or flames and seals out ignitable gases, vapors, and dust. They’re rated T5, an NEC hazardous location temperature classification. This means their surface temperature stays below 212° F to prevent them from reacting with nearby flammable substances. Made of lightweight, durable aluminum with a tempered glass lens, they withstand bumps and rough handling. They’re often used in chemical processing, refineries, and paint spray booths.

Unless noted, the plug and power supply on these lights are outdoor rated but are not explosion-proof rated. Electrical connections must be made outside the hazardous environment.

Light up wet areas—these lights seal out moisture and humidity. They’ll even work in areas with frequent washdowns. Rated NEMA 4X, they withstand spraying liquid, resist corrosion, and keep out dust. Use them with medium-base, screw-in CFL (compact fluorescent), halogen, incandescent, and LED bulbs (sold separately).
