I don’t have both yet but it seems to be the same but maybe some versions are different. There is also many other flashlights with bigger and deeper reflector.
You can contact them by messenger or message only if you are a aliexpress member.
You mean the LED alone when its not being powered ? I have XML2 T6 3C and XML2 U2, the T6 have a darker yellow color (closer to orange) on the LED, the U2 is flashy yellow like lemon.
I still haven’t received my XML2 U3 so I cant tell be it should be even lighter yellow and close to green.
Only the color change but its the same LED. But careful not to base your opinion on pictures because colors are altered by the camera,treatment,compression and your monitor.
True, the colour of the emitter is down to the amount of phosphor and so correlates strongly with tint bins. But output bins are indistinguishable visually with regards the LED itself.
So there can be a 5000k U3 one day ? This can be confusing because warmer color with LED technology have less lumen output than cooler color.
My L2 U3 is supposed to be 7000k.
Just received my C12 XML2 U3, it is brighter than my C8 XML2 U2 but it get hot really fast and the color seem strangely warmer (beam is slightly different but the reflector is the same size) while it was claimed to be 7000k (!?).
I don’t think its a real U3 but its really bright ! Strangely I’m disappoint it is not a cooler light color.
