Dual-Lite Emergency LED Battery Pack, 7W Constant Output, Galvanized Steel w/ One 24 Conduit (Discontinued)

Dual-lite pld7m emergency led battery pack, 7w constant output power, 120-277v, galvanized steel w/ one 24" conduit the dual-lite pld7m is a universal input (120-277v) emergency led battery pack that works with an ac led driver to allow an led lighting load to be used in both normal and emergency operation. it consists of a compact case constructed of durable, galvanized steel with one 24 flexible conduit. The unit contains a solid-state charger with automatic transfer circuit, a 2-wire test switch and led charging indicator light, and a high-temperature, nickel-cadmium battery. due to its steel construction, the pld7m is designed to be mounted outside the led fixture. lumens can be calculated by multiplying the output power of the emergency led driver (7w) by the efficacy of the led load. in many cases the actual lumen output in emergency mode will be greater than this calculation yields, however it will provide agood estimate for beginning the lighting design of the system. lumens in emergency mode = lumens per watt of fixture * output power of chosen product(lumens) = (lm/w) * w
