Do LED light bulbs use less energy?

LED is a highly energy efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs — especially ENERGY STAR rated products — use at least 75% less energy, and last 25 times longer, than incandescent lighting.

Do LED bulbs use more electricity?

LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light. LED bulbs use more than 75% less energy than incandescent lighting. At low power levels, the difference is even larger.

Are LED lights cheaper to run than energy saving bulbs?

The cost saving provided by LED lighting is due to two factors: LEDs require much less electricity to power than both traditional incandescent and halogen light bulbs, and energy efficient light bulbs (CFLs). They last much longer than their incandescent, halogen and CFL equivalents.
