What is LED ?

A light-emitting diode (LED) is a two-lead semiconductor light source.It resembles a basic pn-junction diode, which emits light when activated.When a fitting voltage is applied to the leads, electrons are able to recombinewith electron holes within the device, releasing energy in the form of photons.

LED vs CFL -

Life - LED has upper hand with a avg. Lifespan of 50000 hours as compare to CFL's 8000 hours.

Efficiency Led bulbs have the avg efficiency of 100-120 lumens/watt in comparison to CFL's 50-70

Light Quality LED has 60-90 CRI (color rendering index) as compare to CFL's 60-80 CRI

Energy Consumption per Year A 10W led bulb take 29200 watts while a 20W CFL take 58400 watts

Focused Lighting LED bulb has a light distribution angel of 120 while CFL has a 360 degree angel

CRI (color rendering index) - CRI of a light source is a quantitative measure of its ability to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source.
