Led track light is a track light with LED as the light source, alias: LED track light. It is a kind of track lamp, widely used in shopping malls (clothing stores, furniture stores and other brand stores), car displays, jewelry, star hotels, brand clothing, high-end clubs, Museum exhibition halls, chain stores, brand business halls, professional windows, counters and other key lighting places. It is an ideal light source to replace traditional halogen lamps and metal halide lamps. With the continuous development of electronic technology, new styles emerge one after another in the market, with different shapes and flexible changes.            1. Led track light is a cold light source with no radiation, heavy metal pollution, pure color, high luminous efficiency, low frequency flash, energy saving and health. Ordinary metal halide track lamp is            With the metal halide lamp as the light source, the light-emitting principle of the metal halide lamp is that the heavy metal mercury reacts with the two electrodes after gasification to produce light, which has large heat and radiation, and it must be handled carefully after it is broken, otherwise it may pollute the environment (mercury is a heavy metal element, harmful to human health).            2. A typical feature of LED track lamp is energy saving. For the same brightness LED track lamp and ordinary metal halide track lamp, the power consumption of LED track lamp is only 40% - 60% of that of ordinary metal halide track lamp, which shows its power saving effect.            3. The service life of LED track lamp can reach at least 30000 hours, while the service life of ordinary metal halide track lamp is generally 8000 hours, so it can be seen that the difference of basic service life is great.
