ow led light can have different colors such as yellow,white,blue,red,green,pink,amber, and so on.But do you know how about white car led bulb for work?

The 'white' of white car led bulb comes from the narrow-band blue naturally emitted by GaN car led bulb , plus a broad spectrum yellow generated by a phosphor coating on the die which absorbs a proportion of the blue and converts it to yellow.

Although this blue die + yellow phosphor approach yields light which appears white, it has little green and almost no red content leading to inferior colour rendering compared with incandescent bulbs and even 'tri-phosphor' florescent tubes. 'Warm white' car led bulb, which include a red-producing phosphor, are an attempt to improve this situation as well as make car led bulb illumination more acceptable in living spaces.
