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.
