First, the small
LED is basically a small chip is encapsulated in epoxy, so it is very small, very light. [4]
Second, the voltage is low
LED power consumption is very low, in general LED's operating voltage is 2-3.6V. Only a very weak current to normal light.
Third, long service life
In the right current and voltage, LED life of up to 100,000 hours.
Fourth, high brightness, low-calorie
LED using luminescence technology, much lower heat than the same power conventional lighting.
Fifth, environmental protection
LED is a non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, while LED can also be recycled.
