LED stands for “light-emitting diode”. LED lighting products produce light up to 90% more efficiently than equivalent incandescent light bulbs and can be significantly more efficient than most fluorescent lamps. LEDs come to full brightness immediately with no warm-up delay. Frequent switching on and off does not reduce life expectancy of led lighting. With the adavantages of energy efficient, no toxic elements and long life span, LED light is the best choice to protect the enviroment.
