The LUMIPRO PB Series is a 2'x2' backlit LED flat panel with an integrated emergency driver, sized at 603 x 603 x 37 mm for suspended ceiling grids in offices, schools, healthcare corridors and retail interiors where code-required egress illumination is part of the lighting layout. Output is field-configurable by DIP switch across 20, 25, 30, 35 and 40 W and five correlated color temperatures from 3000 K to 6000 K, with 125 lm/W efficacy, CRI 80 and a 120-degree distribution. The isolated, flicker-free driver accepts 120-277 VAC and supports 0-10 V dimming. SMD2835 LEDs are rated for 50,000 hours in an aluminum housing with a white finish, IP20, for dry indoor locations. The emergency driver uses a lithium-ion battery with a 1.5-hour discharge, 24-hour recharge and self-diagnostic 30-second monthly and 90-minute annual tests. UL listed and tested to UL924 requirements, backed by a 5-year limited warranty.
