XP-G3 is ugly in reflector lights - what about behind optics?

So I haven’t owned one (partially due to the following prevailing wisdom), but apparently XP-G3 LEDs produce ugly tint shifts and are not attractive beam patterns when used in reflector lights.

What about when used under TIR optics - either single or multi?

Does the nature of the optic help “average” out the beam and eliminate the nasty tint shift and rings?

It should ‘average out’ with a decent TIR.
Pebbled surface will always help some more.

My S41S has XP-G3, and it’s fairly even, but i did add a piece of (fairly mild) diffuser sheet.
For the rest i have no experience with them, but 3 are on their way from Fasttech.

I got an XP-G3 R3 4000K 90+CRI triple on a Noctigon from Mtn and while the spot is not too bad the outer area of the spot is quite the rainbow.
Read some similar results after purchase on the High CRI XP-G3 and glad I tested it under the Carclo before mounting it into a light.
It is still in the bag I got it in.
But keep in mind this is the result of the High CRI XP-G3 4000K.
Have an S41S XP-G3 and it is a pretty pure white.

Nichia are not at all bad under optic in any tint or CRI value.

the xpg/xpg2 used to be such a WORKHORSE, its hard to believe they are ruining the “throw king” with version 3… i am hearing more “nichia” now… PITY

same effect can be seen with any frosted tirs.

Cree has always made LEDs with the worst tint-shift through the angle of transmittance, and are horrible when used in reflector based lights, especially shallow SMO reflectors, (like the XM-L horrible original Olight S-series lights with snot-green hue.)
The new XP-G3 is a fine example of LED with bad tintshift, ( reminiscent of the horrible XT-E models) They are ok in narrow-angle TIR optics or Aspherics, but shallow smooth reflectors its tint shift output is garbage.
I bought one XP-G3 to test, and its in my junk bin at the moment and have no use for it because of its bad tint shift.
I like even good tints, especially high CRI or even just a balanced beam pattern.
Pick up any of your current Cree flashlights with a smooth reflector, ( XM_L2, XP-L, XP-G, XP-E XHP, and shine it on a white surface. is the hot spot tint color the same as the flood/corona? NOT likely. even the best neutral tints Cree has, (4C, 3D, ) the hot spot may look nice, but the corona is likely a snot greenish fading to a purple/blue hue across it.
The only LED Cree has that seems to have the best balanced tint across the transmittance angle that stays a good tint is the MT-G2.

Other LEDs like the Nichia 219 has almost no tint shift, thus why the corona & the hot spot are almost the same tint and so much more pleasing to the eye.(along with the superior CRI)

Cree LEDs are only good for super throwers & blasting flooders, not for a good beam color by no means. For those who have any HID and even Incan lights, (and Nichia 219 or Cree MT-G2 lights) the hot spot and through the spill/corona is uniform color and always better on the eye or color rendering.

- Take a close look at second photo in Djozz’s topic here: Cree XP-G3, testing a R3 4000K 90+CRI emitter Look closely at the surface of that XP-G34, you can see around the very the outer edge of the phosphor on the die, it is emitting very GREEN compared to the center of the die area.

Below is a photo from a topic i did a few years back on the cree tint-shift issue. ( notice how the Cree has bad shift compared to the Nichia and even a 50-cent Luxeon neutral white Clone:)

I think a 219C has more tint shift than a 219B.
