HLEBS Explosion Proof Light

The HLEBS Series is a self-contained hazardous location emergency lighting system which is designed for environments known to have high concentrations of gas, explosive vapors and dust. The HLEBS is intended for use in oil and gas refining, chemical production and storage, grain processing and paint manufacture. The HLEBS provides emergency illumination for a minimum of 90 minutes in the event of power outage. The HLEBS emergency lighting system is available in several configurations with direct mount or remote heads up to 300’ from power source. Power is only supplied to the external lamps when AC power is lost. Battery unit must have two heads installed for a total lamp load of 20W (integral or remote up to 300’).

The HLEBS Series housing and lamp-heads are made of copper-free(less than 0.4%) aluminum with a baked on electro-statically applied epoxy for maximum corrosion resistance. The housing contains a nickel cadmium battery which delivers 23 watts to power two external 30VDC, 10 watt lamp-heads. The enclosure, lamp-heads and test station utilize ¾” connection. There are 7 each 3/4” threaded holes in the enclosure.
