Why do LED lights consume less power?

With incandescent bulbs, lighting magic happens before your eyes: Electricity heats the metal filament until it becomes hot, producing light. But with LEDs, technology and sophisticated engineering are carefully packed into the lightbulb. read more

LED Advantages . Use about 80 percent less electricity while providing the same brightness of the incandescents they replace. Use slightly less energy than CFLs. Brighten instantly. Lifespan not shorted by turning them on and off frequently. Some dim as low as incandescents do. read more

Actually the correct question is Why do LED bulbs consume less power. Current without voltage specs is meaningless. Incandescent bulbs emit light by heating a resistive filament of tungsten to very high temperatures, like 3000 degrees C or thereabouts. read more
