FAQs
Yes. The fixture is rated for Hazardous/Classified Locations, complies with NEC/CEC standards, and carries IP66/IP67 protection with NEMA 4X housing, making it suitable for Class I, Division 1 and other hazardous area classifications typically found in chemical plants and refineries.
It operates on 347–480 Vac at 50/60 Hz, which aligns with common industrial distribution networks, reducing the need for intermediate transformers and simplifying site wiring during retrofits or new builds.
The high lumen output provides strong task lighting with a small physical footprint, while the 135 lm/W efficiency lowers energy consumption. Combined with a PF > 0.98, this delivers bright, reliable illumination with reduced operating costs and improved productivity.
The 4 ft length, 3/4 in entry size and flush ceiling mounting simplify integration into ceilings with limited plenum space. Use appropriate mounting hardware rated for hazardous environments to secure the unit, ensuring a clean, unobstructed light path.
