As the first of its kind, the VT1 LED Extreme Environment Vaportite fixture was specifically engineered using thermally conductive polymers for corrosion and UV resistance in harsh environments able to withstand moisture, dust and salt spray. This high efficiency luminaire, weighing only 5 pounds, delivers over 100 lumens per watt. It offers both a 3700 and 7000 lumen package and replaces traditional 32 watt T8 fixtures.
