Default Converting a 200W discharge lamp video projector to LED


"William Sommer******"

I'd like to point out that is no such thing as -- nor can there be -- a
white LED. LEDs are necessarily limited to a narrow band of wavelengths. *
All (???) white LEDs are (I assume) a blue LED with a yellow-fluorescing
phosphor. **

This /looks/ white to the eye, but the red and green wavelengths needed
for color reproduction aren't present.



** As ****ing usual, the Somer****** fool just makes stuff up.

Anyone can Google "white led" and get the facts.

There is plenty of green orange and red in the light from regular white
leds.
