Technical Specs
- Heat Sinks: Extruded aluminum heat sinks provide optimal thermal management, decreasing LED junction temperature and ensuring long life and high efficacy. In addition, we attach the LED boards to the heatsink using a high quality thermally conductive adhesive instead of screws. This promotes long life even at high ambient temperatures
- LED Boards: FR4 PCB is used to limit stress on solder joints by matching coefficient of thermal expansion between the LED and the PCB more closely
- LEDs: Only high quality LEDs are used to deliver maximum light output and longevity.
- Power Supply Access: Wireway cover is captured and hinged, opening over 120° for hands-free, easy access and quick wiring. Center hole accepting 3/4” stem and also 1/2” KO near top end of wire way.
- Wire Guards: Optional factory-installed wire guards for the fixture and OCC occupancy sensors are available.
- 120-277V or 347-480 (50/60Hz), Typical, depending on model.
- Power Factor: Greater than 0.9 (0.96–0.99 typical).
