Tri-proof LED lights are waterproof, dustproof and corrosion-resistant fixtures constructed that dust not enter the enclosing case. They're enclosed and gasketed for application in damp or wet locations. The body is fabricated from corrosion resistant, glass reinforced, auto extinguishing polyester. The diffuser is impact-resistant polycarbonate. The luminaire is offered with stainless steel diffuser clips and a stainless steel suspension kit. While regular LED luminaires are not intended to be employed inside moist and dusty conditions, LED tri-proof light fixture assembly has been purposefully designed to fit this need. The LED chips are mounted on an aluminum circuit board (PCB). PCB is mounted on a flat base aluminum plate as part of the heat sink for optimum heat dissipation. Efficient LEDs and drivers provide high performance and great energy savings. This linear LED luminaire has been optimized for parking garages, cold storage facilities, car washes, barns and arenas, manufacturing environments, and harsh and wet environments. Rated at IP65, it is designed to be dust tight and moisture tight against jets of water from any direction.
