How do LED light bulbs work to reduce energy use?

Direction: LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. … Heat: LEDs emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat.

How do LED lights use less energy?

A light emitting diode (LED) contains a semiconductor. Light is therefore emitted directly from the source input, without first powering a separate light emitting load (e.g. filament). … In this way, LED consumes less power than rival technologies.

Do LED lights waste a lot of electricity?

Yes! LED lights consume 80-90% less energy than incandescent bulbs, and last up to 100,000 hours, versus 3,000 hours for an incandescent. Combine this with the durable construction of LEDs, and savings extend beyond electricity.
