Due to its special construction, the lighting of dangerous atmospheres inside and outside the lamp is avoided through several solutions. First, air flows into the lamp housing and creates overpressure before it flows into the generator housing. If the lampshade or the protective glass is damaged, and the air flows out first. The generator stopped immediately and could not cause any flame in the bulb. The exhaust air prevents the penetration of explosive gases in the lamp and also cools the screw of the broken bulb.

The lamp housing is made of brass or aluminum.
