The LED light is made of 3 main components: An LED module (a set of chips that emits light), a power supply (converts voltage, stabilizes current) and a cooling radiator or specially designed body (guarantees cooling). The radiator (body) distributes the heat from the light emitting diodes and the driver. A longer service life is ensured by releasing quality controlled heat from the LED modules and the power source. In addition, light emitting diodes convert electricity into light more efficiently than other light sources, so to replace a 400W metal halide light, a 150W-90W LED light is enough.
