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.
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.

| 12W*8*365=35Kwh | 40W*8*365=116.8Kwh | 233% |
3. Comparison table for Working Life-span
| LED | Incandescent Bulb |
| Approx 50000 hours/Pcs | Approx 1500 hours/Pcs Bulb |
| 1Pcs LED | 33Pcs Bulb |
- The LED is much more energy efficient and environmental friendly than Incandescent Bulb and CFL.
- LED lighting will be the best decision for you.
