FAQs

Installation is designed for flush-ceiling mounting with a 4 ft fixture length. Use the 3/4 inch entry points for wiring, ensure a proper seal to maintain IP66/IP67 protection, and connect to the universal voltage range (120-277 Vac or 127/250 Vdc). Confirm mounting height and room layout to achieve optimal wide distribution and uniform lighting across the target area.
Verify voltage range 120-277 Vac or 127/250 Vdc, 50/60 Hz operation, wattage of 59W, and lumen output of 8000 lm with a power factor > 0.94. These specs enable predictable energy use, compatibility with site power systems, and consistent illumination in hazardous locations.
