Interesting. I assumed that "white" LEDs were actually a combination of R,
G & B LEDs.

This also explains why Flare and Blue fringes from directly imaging LED
lamps is such a problem. White LEDS produce quite short wavelength blue
light ,that is then converted to green and red by phosphors,but there is
still a very large blue component,often larger than the Green and Red
,especially with High color temperature,high efficiency LEDs.
