Thank you freeme.
Some pictures S41S with XP-G3 LEDs.
‘White’ and ‘Black’, ‘Colored’ with Nichia is on the way. 
Left XP-G3 LEDs right XP-G2 LEDs
One double hole in the Astrolux S41S.
Nice Bluzie! How do you like the xpg3 tint and output?
I am loving the aggressive looking knurling. Can’t wait to get mine!
Those are very helpful numbers. Thank you for composing that :+1:
BG is fast.
Astrolux S41S Colored with 4*Nichia219B
Presumably, the colored ring is caused by the bezel.
—————————Nichia219B, ———————— XP-G2,—————————— XP-G3
Wauw nice trio!
Interesting to see the bezel reflection in the wall shot
Does the bezel artifact vanish at a longer distance?
I’m diggin that rainbow one. Mine should arrive shortly. That’s a very purple beam though.
If you are critically i’m afraid, yes.
I thought the color would be different for the 219, almost looks cooler than the other two?
Astrolux S41S Colored with 4*Nichia219B
thanks for the pics.
Nichia219B got purple tint eeewww
XP-G3 got wierd yellow hot spot kind weird too. …Not a nice transition from corona to spill
I don't feel that those beamshots do justice for S41S 
Triple XP-G2 S2 with Carclo 10507 optics (LEFT) - S41S Quad 219B (RIGHT) / ~5cm from wall.
There is clearly more artifacts with Carclo setup with naked eye than S41S.
Triple XP-G2 S2 with Carclo 10507 optics (LEFT) - S41S Quad 219B (RIGHT) / ~12cm from wall.
sometime using wrong white balance on camera can effect the outcome and those phone camera /auto modes are hopeless 
So far i got 2 nichia stainless steel already and waiting for 2 more XPG 3 colour version coming
Ordered from BG, Nichia + Tube + Holster.
Wasn’t there beamshots of the XP-G3 earlier and they were more/closer to NW? I hope the one I get is not as purple as the shots just above this :(!
EDIT: Actually, the beamshot I mentioned, comparing the emitters, is in the OP.
I got my s41s with xpg3 and it’s got a purple ring around it at low levels. And it gets purple center on higher levels which are visible even at distances. Why is that?
My s41 which is a xpg2 is more towards neutral white and much better colour. Also a lot brighter. 
It also over heats sooo much. Only 20 seconds and I had to let go of it because it was so hor. Something is wrong. While the s41 wasn’t even warm at turbo.
Also when I try the 0.5 seconds to go a level back it simply goes to low. So whatever level I’m at and I hold for 0.5 it goes to low.
At second level. S41s on left s41 on right.
At turbo s41s on right s41 left.
After having a look. It seems two of the leds are much less bright than the other two. It’s not an angle thing. They also have a purple tint.
Something looks wrong in there. But I can’t seem to open it up to check.
This is no good. Is that a colored or SS version for XP-G3 S41S? I wonder if he blue hue was due to the bezel or optics.
That’s what I was wondering also (where the purple is from and why the brightness diffs).
Of the ones who got theirs already, are they really glued? Anyone tried to disassemble theirs?
Ouch, there is clearly something wrong with the emitter and optics. You probably want to pop it out to check.
It’s the ss silver. Not the coloured. My colored hasn’t arrived yet.
So it’s a ss xpg3. But look at the photo of close up led. Something is wrong.
