I presume, it is an XM-L or XM-L2 LED and this phenomenon is “known” as “Cree rainbow”.
If you google this site for “Cree rainbow”, you’ll find lots of explanations.

thanks. i just like to know what color will i get with the S lights. also i searched that terms and didn’t found much.

This color shift only plagues the XM-L(2) and XP-L LEDs, because of their big die. The smaller LEDs, like XP-G(2) don’t suffer from that, because of their lot smaller die. If you want to be absolutely sure to get no color shift, choose a Nichia 219 or Osram Oslon emitter for your light.

[edit]
To preview the tint (color of the LED) i refer you to ANSI White - Flashlight Wiki
In the chart (http://flashlightwiki.com/images/c/cb/Ansi-white.jpg) you can see what tint bin (number) refers to which color.

hi
the T6-4C is what i want, my question is not about the different cree’s colors, it’s about how the color will looks like with S3/S8 reflector.

The “Cree Rainbow” isn’t changed much by the reflector, at least in the lights I’ve converted to XM-L. I found a TIR optic in the 20mm S5-sized lights does an amazing job of blending that rainbow into a ball of creamy, sweet WHITE. YMMV, of course, as I haven’t tried all the TIRs.

I notice the same thing with my C8 sized lights, the spill is predominately blue and the spot yellowish white by contrast. My S2 is mostly all flood so the bluish spill and big yellowish corona are mostly mixed and it definitely looks whiter overall from center to edge. My dedomed C8 doesn’t really show a tint difference between spill and spot.

thanks, that’s helpful
would you say the s2 (with T6-4C?) is producing a white color or a little yellow?
