The EPL-TL-C-F explosion proof portable tank light with a manhole mount flange option is rated Class 1 Division 1 and uses a 400 watt metal halide lamp to produce 75,000 lumens of light capable of illuminating 20,000 sq. ft. of work area. This unit consists of a 400 watt metal halide lamp mounted on top of an aluminum cart with solid rubber wheels and provides a portable and easily mobile source of hazardous location illumination. This unit is available in 18" and 24" diameter and is considered a universal tank light as it can be easily passed through most conventional manholes and entryways. To provide added versatility to this tank light, we developed a flange mount option that enables operators to mount the light head in a suspended position from an overhead man way. The flange wraps around the edges of the man way and the light is mounted to the flange assembly via an included threaded brass rod.
