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.

LED is basically a small chip encapsulated in epoxy resin, so it is very small and light. Low power consumption LED power consumption is very low, generally speaking, the operating voltage of LED is 2-3.6V. The working current is 0.2-0.03A. That is to say, it consumes no more than 0.1W of electricity. Long service life Under proper current and voltage, the service life of LED can reach 100000 hours.
