Dual-Lite PLD7M2 Emergency LED Battery, 7W Output Power, Galvanized Steel w/ Two (2) 24 conduits

Dual-lite pld7m2 emergency led battery pack, 7w constant output power, galvanized steel w/ two (2) 24" conduits the dual-lite pld7ms 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 two 24 flexible conduits. 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 pld7m2 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
