How do I set my LED light to white?
How to make a white LED
- The RGB approach. The output from several different LEDs, typically red, green and blue, is mixed.
- Phosphor downconversion. The light emitted from an LED chip passes through a phosphor material which “downconverts” a portion of the light.
Why does blue red and green make white?
A representation of additive color mixing. Projection of primary color lights on a white screen shows secondary colors where two overlap; the combination of all three of red, green, and blue in equal intensities makes white.
What three colors make up white light?

What is the yellow stuff in LED lights?
The yellow color you see on bare LEDs are the color of phosphor, which is used to convert the blue light emitted from the chip into a wide spectrum, the visually white light. Different phospher recipe creates different quality of white lights – color temperature (CCT) and color render index (CRI).
Why are white LEDs yellow?
Most white LEDs on the market are actually a blue LED chip with a yellow phosphor coating. To create yellow LEDs, many manufacturers will put yellow lenses on the outside of a bulb. Whenever any hint of blue shines through a yellow lens, the yellow and blue combine, producing more of a green color–not a good look!
