申海防爆
防爆燈一般採用金鹵燈，內建補償防水. It’s important to note that explosion-proof fixtures must use the original light source and not be fitted with LED sources by oneself.
The operating temperature of the fixture is different from the highest temperature of the light body. If you want to control the maximum 溫度 of the outer casing, then you must choose an LED source with a lower temperature.
一般來說, as long as metal halide and high-pressure sodium lamps do not exceed a power of 400W, a T4 or T3 classification is sufficient.
