About Color Temperature
Cold light and warm light are defined by color temperature.
Many peop don’t know whether they should select the warm white led bulb or cold white led bulb while decorating their house. I can only say each one has their one standard for the color . Personally, for the bedroom, I will choose warm light, which is conducive to sleep；for the living room ,i will choose cold white ,which is bright enough to do some actions
The color temperature exceeds 5000K time color is blue, giving a person a cold feeling, called cold light;When the color temperature is below 3000K, the light color will be red, giving a warm feeling called warm light.
Light with low color temperature is yellow, such as incandescent lamp, about 2800K, while light with high color temperature is blue, such as violet lamp, more than 9000K.
It is generally believed that the color temperature of standard white light is 6500K, and the white light emitted by CRT is about 5500K. The effect of increasing or decreasing the color temperature can be simulated by slightly changing the mixing ratio of the three primary colors. The change process of photography, camera, display and other equipment by using the principle of color temperature is called the color temperature effect.

Warm White
The color temperature of warm white is less than 3000K.It make people feel warm and relaxed.Warm white led bulbs are best choice for bedroom and living room.
-
Pure White
The color temperature of pure white is 3000K-5000K.Pure white LED bulbs are suit for study lamps.The color temperature is determined by the composition of blue light and yellow-green light. The higher the blue light component, the higher the color temperature; the lower the blue light component, the lower the color temperature. Therefore, if the color temperature is too high, the blue light content will be relatively high, and the high energy blue light will damage the retina.

Cool White
The color temperature of cool white led bulb is more than 5000K.Cool white LED light bulbs are best suited for office, because these places require bright light for us to work.
