The XP-G3 and the mystery of the disappearing luminance

uh, LOL!
feel free… I already got told to get my eyes checked, and to buy a new monitor

There must be some kind of GreenSlider Effect, that makes me see green in HDS LEDs, (I also see PWM in HDS lights)… maybe its the fact that my house lighting is 3000k Incandescent… Or all those years hanging out at Baudelaires are causing flash backs… hmmm

.

thanks
yes, Flip chips are a problem in flashlights with clear optics.

A test of a Bare XP-G3 LED can show tint below the BBL (negative DUV),

and then when the LED is in a light, the reflector can capture the side light coming off the flip chip, and produce a Greenish/Yellow Donut, with tint above the BBL (positive DUV).

I find it very confusing to be told that a Bare LED has negative DUV, and then see a photo that clearly shows tint above the BBL…

.

here is another example of an LED that when tested Bare, the Tint comes out below the BBL, negative DUV,
and when it gets into a flashlight, the tint changes to be above the BBL
