100W Explosion Proof LED Light - 1x4 Lay-In Troffer
C1D1/C2D1 - Paint Spray Booth - Front Access
Instruction Manual
This explosion proof light is designed for illumination of industrial locations. It uses the latest in
solid state lighting technology for long life, low maintenance and high efficiency.
The unique design focuses the light where it is needed, giving improved efficiency over a
conventional HID luminaire.
An internal, universal input, power-factor-corrected switch-mode supply allows it to be used from any
nominal single phase power supply within voltage marked on nameplate without any variation in light
output.
