Read MoreCompared to conventional incandescent bulbs LEDs have many advantages. They are economical to use energy as compared to prior generations of electric light sources - arc, filament and gas discharge. For an optimal power supply circuit design and application of high-quality components average lifetime of LED lighting systems can be increased to 100 thousand hours, which is 50-200 times more massive than incandescent bulbs and 4-16 times greater than that of most fluorescent lamps.
