What is a component LED?
A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons….Light-emitting diode.

How long does a single LED last?
Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!

What are main components of LED bulb?
The Anatomy of a LED Light Bulb
- Lens/Optics. Due to the brightness of LEDs, a lens (or optics when used on omni-directional lamps) is used to evenly distribute the light.
- LED Chips. LED chips are the components that create the light.
- Heat Sink.
- Circuit Board/Driver.
- Housing.
- Base.
