Ceramic metal halide grow light is developed on the basis of high pressure sodium lamp and quartz metal halide lamp, but its use has far exceeded both. Its high color rendering makes it possible to replace incandescent lamps and halogen lamps in large quantities, especially low power types such as 20W, 35W (39W), 50W, 70W, and so on, which have also been widely used in indoor and even household lighting. The medium power lamp, including 315w ceramic metal halide grow light
, has the characteristics of high color rendering, high light efficiency and long life. Therefore, even though 315w ceramic metal halide grow light are widely used in indoor and outdoor areas, such as airports, stations, shopping malls, Hotel lobbies, restaurants, etc. Even though the cost is high, 315w ceramic metal halide grow light and higher-power ceramic metal halide lamps can be seen everywhere in Europe.
At present, the production and use of ceramic metal halide grow light are mainly concentrated in Europe and North America. The output of ceramic metal halide lamps in the world is increasing by more than 30% every year, but there is still a shortage of supply. Due to the technical difficulties and intellectual property problems, it is still produced by GE, Philips and Osram. Many parts of our country have been developing but have not succeeded. The research and development of this kind of light source is not only facing the material and technology key which is difficult to overcome, but also the intellectual property problem which is more difficult to deal with. At present, our government is making great efforts to rectify and protect intellectual property, which makes the patent problem of ceramic metal halide lamps more complex and difficult.
