The SHOT Explosion Proof Solid State Lighting Fixture (EPSSLF) is the "next generation" explosion proof fixture incorporating state-of-the-art, high output LED's. A properly sized LED light grid and associated power controller card will guarantee a long, maintenance free life at least 50 times longer than the current incandescent lamp. The SHOT system takes advantage of the currently approved for use Symbol 48.2 fixture housing. This cast aluminum housing is an excellent heat sink capable of wicking away a significant amount of LED junction heat through convection and conduction. What's significant is the modifications to the housing can be performed with little impact to the current explosion proof configuration the Symbol 48.2 is widely know for and with the inclusion of the SHOT LED system, an unbeatable combination capable of surviving the harshest of environments will be formed. The SHOT EPSSLF will be a cost effective replacement savings thousands of dollars annually across the DOD.
