    This explosion-proof light has an incandescent lamp and is available in five lens colors – amber, blue, clear, green and red. Model 121X is unique to the market because it covers an entire range of possible mounting configurations-including dome up.

    This corrosion resistant unit’s copper-free aluminum housing is finished with a powder epoxy. All exposed hardware is constructed of 316 grade stainless steel.
