Environmental LED is made of non-toxic materials. Unlike fluorescent lamps, which contain mercury, it will cause pollution. At the same time, LED can also be recycled. Durable LED is completely encapsulated in epoxy resin, which is stronger than bulbs and fluorescent tubes. There is no loose part in the lamp body, which makes the LED not easy to be damaged.

The best LED on the market is 32 lumens per watt, which is twice that of tungsten filament bulbs. And people can predict that 60 lumens per watt will be emitted, and LEDs as bright as fluorescent lamps will appear in 2004.
