When the tube rupture starter layer is also damaged, lights that turn off) proof lighting selection, low cathode temperature (about 200 ℃), is a safe and practical proof light fixtures _ pictures, very fit into increased safety type lighting. Eco-friendly self-ballasted high pressure mercury lamp light source is the use of high-pressure mercury vapor discharge lamp incandescent light sources and hybrid body and three substances emitting phosphor. It has a high brightness, simple structure, the advantages of starting fast. Shortcomings in the past to change the high pressure mercury lamp ballasts require additional use of tungsten lamps to play a role in limiting corrosion proof, but also improves the light color. The disadvantage is that relative to the normal fluorescence lifetime to shorten some of the high-pressure mercury lamp. HPS is a high-pressure sodium vapor discharge lamp with high luminous efficiency, low power consumption, high capacity through the fog, long life and other advantages of the explosion-proof safety exit signs, factory direct supplier obvious price advantage, the company provides secure proof of export Quality Indicator over supply) sales explosion-proof lights / supply) sales explosion-proof lights / exit lights and explosion safety / explosion lights products, the company has a good reputation in the market, professional sales and technical service team, with operating explosion-proof lights / ... proof safety exit light / explosion-proof lights products, the company has a good reputation in the market, professional sales and technical service team, with operating explosion-proof lights / ... proof lighting pictures, Handan proof lighting, but manufacturers Feng explosion proof Koretoyo provided by Zhejiang Electric Co.
