The long life LEDs and driver make this <br />hrs at 25°C, L77). Class 2 electronic driver has a power factor >90%, THD <20%. Easily- <br />luminaire nearly maintenance-free. <br />serviceable surge protection device meets a minimum Category B (per ANSI/IEEE C62.41.2). <br />CONSTRUCTION <br />INSTALLATION <br />The single-piece die-cast aluminum housing integrates secondary heat sinks to optimize thermal <br />transfer from the internal light engine heat sinks and promote long life. The driver is mounted in <br />down for easy access while making wiring connections. The integral bubble level on the <br />direct contact with the casting for a low operating temperature and long life. The die-cast door <br />mounting plate provides assistance for level placement on every installation. <br />frame is fully gasketed with a one-piece solid silicone gasket to keep out moisture and dust, <br />providing an IP65 rating for the luminaire. <br />LISTINGS <br />FINISH <br />rated and suitable for wet locations when mounted with the lenses down.
