Since LED light bulbs is cold light source, semiconductor lighting itself without any pollution to the environment, compared with incandescent, fluorescent, energy-saving efficiency can reach 90%. Under the same brightness, the power consumption of only ordinary incandescent lamp 1/10, fluorescent tubes, 1/2, green and healthy energy saving, led lighting bulbs average life of 500,000 hours, 10 times longer than conventional bulbs, and quick start, no flicker
