Which LEDs? LEDs are pretty much all giving off the same two colors to make white: blue and yellow (in a single chip made of a blue LED and yellow uv-reactive phosphor). Warm white, cool white, same thing just varying intensities of each color. Only cheap color-changing LEDs (now) will use R/G/B chips lit together without dedicated white chips. What wavelengths are they tracking?
Shout out Shuji Nakamura, inventor of the blue LED. Kinda broke the whole thing wide open.
I also watched that last week.
Watched that video last night. That was more fascinating than it had any right to be.
I've been an electronics nerd since the 70s, and somehow never noticed blue LEDs becoming a thing.
why would they break their own invention?
