FAQs
The fixture is designed for flush ceiling mounting with 3/4 inch entries, enabling straightforward installation in restricted ceilings. Ensure power is disconnected, then mount using approved brackets and seals suitable for Class I, II, and III locations. Wiring supports 120-277 Vac and 127/250 Vdc configurations, with a 4X/NEMA rated enclosure to maintain compliance during retrofit or new-build projects.
This light carries NEC/CEC compliance with hazardous location ratings including Class I, Division 2 and Class II, Division 1, Class III, and Zone 2. It also features NEMA 4X construction and IP66/IP67 ratings, providing robust protection against ingress and corrosion in demanding environments such as chemical plants and refineries.
Yes. The flush ceiling mounting and standard 4 ft (with 39 in body length) footprint support retrofit installations in spaces with limited access or obstructed ceilings. The range 120-277 Vac plus 127/250 Vdc compatibility simplifies integration with current electrical architectures, while the 59W design delivers high efficiency with minimal ballast changes.
The 8000 lumen output at 59W delivers about 135 lm/W with PF > 0.94, reducing energy use versus older lighting while extending service life due to rugged copper-free aluminum housing and diffused polycarbonate lenses. Lower maintenance, fewer replacements, and improved uptime in hazardous locations translate to faster payback and lower total cost of ownership across sites.
