Hazardous Location Ceiling Lights



These lights are UL listed or CSA certified for hazardous locations where flammable/combustible gases, vapors, and liquids may be present. They have a sealed lens and can be hardwired to operate on any of the voltages listed.
Styles 1-2 can be used where hazardous material occurs infrequently. They have built-in LEDs that last longer, are more efficient, and generate less heat than other light technologies. Style 1 are housed in durable stainless steel. Style 2 have an acrylic lens that won’t turn yellow over time.
Style 3 withstand hazardous material under normal operating conditions. Housed in lightweight aluminum, they have built in LEDs that last longer, are more efficient, and generate less heat than other light technologies.
Lights with a cool appearance highlight white/blue tones that are good for inspecting.
All are IP66 rated for protection from washdowns. IP67 rated lights can be briefly submerged. NEMA 4X rated lights protect their parts from corrosion.

Hazardous Location Bay Lights

Use these lights in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 30-ft. high. They are ETL and C-ETL listed for Class I Division 2 Groups A, B, C, and D, Class II Divisions 1 and 2, Groups E, F, and G, and Class III Divisions 1 and 2 for use in environments where ignitable concentrations of acetylene, hydrogen, ethylene, and propane occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. With built-in LEDs, these lights last longer, are more efficient, and generate less heat than other light technologies. They produce a neutral light appearance, which creates a balanced environment for general work areas. These lights produce a wide beam of uniform light. Lights can be hardwired to operate on any of the voltages listed. Thread onto 3/4 NPT conduit to suspend lights from the ceiling.

High-Temperature Hazardous Location Ceiling Lights

Built for hot, hazardous areas such as steel mills and refineries, these lights work in temperatures up to 212° F. Rated NEC Classes I and II, they’re safe to use where there are ignitable concentrations of flammable or combustible gases, vapors, liquids, and dust. Rated IP67 and NEMA 6, they’re sealed against humidity, washdowns, and even temporary submersion. They’ll also stay sealed in dusty conditions.
Mount these lights with the included bracket. It tilts to direct light where you need it.
These lights last at least a year when used at 212° F continuously. And at 131° F, they’ll last almost 7 years.
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.

Hazardous Location Emergency Backup Lights

These lights are UL listed for Class I, Division 2, Groups A, B, C, and D for use in environments where ignitable concentrations of hazardous material occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. They withstand acetylene, hydrogen, ethylene, and propane. Lights can be hardwired to operate on any of the voltages listed. They have a low-voltage disconnect so they won’t drain the backup battery. Use the test switch to check that the heads and battery are working properly. Heads adjust to any angle to direct light where needed. They cannot be sold to the listed areas due to energy efficiency requirements.

Explosion-Proof Dock Lights

Safe to use in areas with ignitable concentrations of flammable or combustible gases, vapors, liquids, and dust, these lights are rated NEC Class I, II, and III. Their housing contains fire and sparks, so they won’t ignite what’s in your environment. They’re rated T4A, an NEC hazardous location temperature classification. This means their surface temperature stays below 248° F to prevent them from reacting with nearby flammable substances. These lights swing out from the wall, and their head tilts and swivels to illuminate loading docks and trailers. UL marine listed and NEMA 4X rated, they stand up to salt water and other corrosive liquids, and they’re sealed to withstand washdowns.
Their lens is tempered glass, so it resists scratches and impact during loading and unloading. Since the lens is clear, the lights give focused illumination that is useful for tasks and spot lighting. The LEDs emit a cool light that highlights white and blue tones and has a brighter appearance than neutral light.
