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.

The LED is much more energy efficient and environmental friendly than Incandescent Bulb and CFL.
LED lighting will be the best decision for you.

DescriptionThis has no ballasts to burn out like other plant light is new and never used. It is a LED light bulb with a long lifespan. Extreme energy efficiency permits this new LED panel to pay for itself many times over each year in electricity savings. No IR or UV light radiation. With this you can do the plants in the greenhouse or laboratory, and can completely replace the natural light, to promote plant growth. It is ideal for plant growth, flowering, fruiting.

FEATURES

Uses wide-angle LEDs for max coverage & output
Silver-reflective board under LEDs increases efficiency
Wavelength type is rich, coincided with the plant photosynthesis and photomorphogenesis
Whether in the evening or night, you can effectively extend and control of plant science needed to light
Plants in the greenhouse or laboratory, can completely replace the natural light to promote plant growth
Can be used for orchards, plant plant, garden, greenhouses, indoor planting crops, seeds and other places
As a supplementary light, any time of day can enhance the light, you can extend the effective lighting hours
Both in the evening or night, can effectively extend and control of plant science needed light
