Fourth, it is because the heat generated by the LED lights, so it needs for cooling. Compared with the light weight plastic, the thermal conductivity of the metal is much better, but also bulky enough.
Five, Light perception. In fact, it is not a fatal flaw of LED lighting. LED lighting industrial products under the case of the less electricity, and the reason for the issues of the heat for long time, it is because the LED lighting stimulate the visual sense. But such light is too strong, and if with the quality of the shade or baffles, or in large part to address this glaring problems.
Six, with regard to prices, after read the first five principles, it is self-evident.
LED Flood lighting is not that energy-saving on the matter, the key is to make consumers feel affordable and reliable.
The word "hot" in LED lighting field is sensitive. A word "hot" make a number of enterprises exhausting and make many consumers are neurotic. In the area of LED lighting. LED lighting industrial brand in the Chinese market could get almost none. The reason is simple, it can not solve the "hot" issues.
China professional LED lighting companies seem to have a lot.

In fact, look at the entire China market, LED lighting products capacity is not large enough to hold up more than one billion people in China's consumption. So LED lighting industrial gets hot. How long does it sustained? How to continue the fire? This is the number of LED lighting enterprises and the people involved in the LED products, we can easily see that put in the LED lighting industry, the most urgent and the biggest problem is the "hot" instead of "heat"!
We use the foreign machinery and equipment to produce chips, or chips imported from abroad with foreign machine package, and then the foreign machine package, and then the foreign machine processed into finished lamp, however, it is still hot, so then we sold superior products abroad and let the foreigners pick and choose. Why is the Chinese high-tech is always dependent on foreign? More certain businesses even "imported" as the back of the brand's quality.
