M 30 x 1,5     example of use         Light fittings type 26101 are used where spacious working stations have to be illuminated with gright diffuse light       - tank - ships - canalisation - boiler plants - refineries - chemical industrie         The lamps can be used in all hazardous areas zone 1 and zone 2.   description         Due to its special construction an ignition of hazardous atmosphreres inside and outside the lamp are avoided by several means. At first the air flows into the lamp housing and generates an overpressure before it flows into the generator housing. housing to drive the turbine wheel of the AC-generator to induce the voltage for the bulb. If the lamp housing or the protection glass is damaged, the air flows outside first. The generator stops immediately and cannot induce any voltage for the bulb. The exhausting air prevents a penetration of explosive gases inside the lamp and can cool the spiral of a broken bulb, too.
