Purpose of Warm/Cold LED modules with RGB LEDs

Question

RGBWW (aka RGBCCT or RGBCW) comes with cool & warm white temperature LEDs. Marketing states instead of standard 16M colors (2^8^3) that is now allows over 1T colors (2^8^5). Some even come with only a cool or only a warm white LED.

I don’t understand though, RGB can mix to form different temperatures of white on its own.

Televisions/computers/phones only use RGB (or BGR).

Answer 1

There are actually colors that you can’t get from the RGB color space.

But the real reason for separate white modules is that you can get the white color you want, you can get it efficiently with a high efficiency, and get the CRI that you want.
