Flameproof explosion-proof lamps and explosion-proof ballasts
are manufactured in aluminum alloy die-cast. The surface of the
bodies is sprayed epoxy resin powder, therefore they have good
anti-corrosion performance so as to satisfy the requirements in
chemical, petrochemical and sea industries.

Flameproof explosion-proof lamps comprise aluminum alloy
bodies, reflectors, toughened glass transparent parts and guards.
Spigot joints are adopted so as to have the functions of opening
covers quickly. Flameproof explosion-proof floodlight lamps are
used for large range illuminating in the circuits of AC220V, 50Hz.

Mercury vapor lamps, high pressure sodium vapor lamps, metal
halide lamps are fitted with explosion-proof ballasts.
