The Kelvin Scale:

Color temperature is a kind of visible light that has important applications in lighting. The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source. Color Temperature is a measurement in Degrees Kelvin that indicates the hue of a specific type of light source, the symbol of unit is K.

Different color temperature light of source also offer different light color, it will bring you a different feeling:
- Higher color temperatures (5000K or more) are "cold", color is green to blue.
- Moderate temperature (3000-5000K) are "cool", color is white.
- Lower color temperatures (2700-3000K) are "warm", color is yellow to red.

Type of Fitting:

These pictures below display the most common fittings. If you know your fitting, you can easily find the right LED bulbs to match.

LED, Incandescent Bulb and CFL of these three different type

1. Luminous Flus & Application Efficiency

LED	Incandescent Bulb	CFL
1W	25W	-----
3W	40W	5W
5W	60W	12W
7W	100W	24W
9W	150W	30W
12W	250W	40W

LED saves 60% of energy compared with CFL.
LED saves 90% of energy compared with Incandescent Bulb.
