80% uplight with batwing distribution and 20% downlight.
Electrical
Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality of illumination for extended service life. Grad is rated to deliver L80 performance for 50,000 hours. Standard 010V driver dims to 10%; eldoLED driver options deliver choice of flicker-free dimming to 1%. Optional integrated nLight controls make each luminaire addressable -- allowing it to digitally communicate with other nLight controls such as dimmers, switches, and occupancy sensors using standard Cat-5 cabling. Optional Lumen Management ensures constant lumen output is maintained over the system life.
