The difference between LED and traditional lights

LED (Light Emitting Diode), light emitting diode, is a semiconductor device capable of converting electrical energy into visible light in the solid state, which can directly convert electricity into light. While traditional lamps are generally heated filament to incandescent state, through thermal radiation to produce light, which wastes a lot of heat energy, that is, power consumption. So LED lamps and traditional lamps in the power saving rate is 50% -70% lower. And the service life of LED lights is generally 3-5 times that of traditional lights. From a more professional point of view, its color rendering index, color temperature, light decay, environmental protection and other aspects are better than traditional lights. Of course, its most important feature is still power saving, because of this the National Energy Office will promote LED energy saving retrofit program in the country, vigorously support the LED industry. But because of the current LED lamps and lanterns of a single high cost, generally not suitable for home, and suitable for commercial lighting (half a year's savings on electricity will be able to offset the cost of lamps and lanterns, and later to save the electricity is equivalent to the business earned). Downstairs answer I beg to differ.
