1. During the processing process, there are heavy metal pollution after the application of waste. At this stage, European and American countries attach great importance to heavy metal pollution. The Chinese also understand the adverse effects of heavy metal pollution.

2. Because it is FRP product, fragile, not easy to transport, not easy to install.

3. The electricity consumption is still a bit bigger.

4. It is very easy to destroy, the cycle is short, and the environmental protection and energy saving is not cost -effective. This means that it is best for the real portrait.

4. What are the advantages of LED lights?

1. Environmental protection and energy saving. The energy consumption of the white light LED is only 1/10 of the fluorescent lamp, 1/4 of the LED energy -saving lamp.

2. Long life. The service life reaches more than 100,000 hours. It can be said to be "all overwhelmed" for ordinary people's lighting lamps.

3. Can be able to work in the speed of the work. LeD energy -saving lights If you often start or turn off the tungsten wire, it will become dark and quickly damage.

4. Solid packaging, belongs to the type of cold light. Therefore, it is very convenient for transportation and installation. It can be equipped with all small and closed machines and equipment. It is not afraid of shocks, and most of them do not need to consider heat pipe heat dissipation.

5. LED technology is developing rapidly. Its high efficiency has been shiny and high -efficiency has achieved shocking improvement, and the price is continuously decreasing. A white lamp LED came to the house quickly.

6, environmental protection, no harmful objects without mercury. The assembly of LED lights can be easily disassembled, and it can be acquired according to other people without the need to acquire manufacturers.
