That’s why I thought it was UV, too. My purple S2+ has a UV emitter, ie, I took the guts from a black-body UV light and stuck them in a purple host.
My green UC20 at least has a green tailswitch button, too, ’though that was come-with. 
Sofirn HS05
Lined up against some other right-angle lights:
FWAA polished Ti SST20 4k.
My newest arrival yesterday: Nicron M1.1.
It is now my smallest flashlight, just about one-third the size of a Sofirn C01S.
@TermsakC:
There is a link in my signature on how to post pics on BLF. 
Did not unseal it for a pic, but got my new FW3A C from Neal today. I have been putting this one off for to long and the recent discount pushed me over the edge. Equipped with 4000k SST-20’s. Ordered on the 5th from Neal and made it to the cornfields of IL today. Really good shipping times on the last few orders from him.
Skilhunt H04 from AE with a missing screw.
But saved by the magnet on tail cap.
My latest arrival from Banggood this afternoon (after 43 days of waiting): a copper Astrolux FT03 Mini.
Wow - that’s a very strong magnet to pull it out of the head!!!
But seriously, strange that the screw was missing but somehow still included with the flashlight. I guess you got lucky?
That triple is really green, what emitters are they?
That’s crazy and oddly cool except for the loose screw thing.
FWAA SST-20 4000k
Body Flipped:

It’s actually the GITD insert underneath the TIR that’s showing as green.
I still have no idea how the screw got loosen during storage in their warehouse or during the shipment.
After I put back the screw, it’s back to normal. No loosen thread.
Astrolux EA01S / SST40 / 5000K
Just arrived today, Convoy 4x18a for modding with a new reflector. 
Hoping I can squeeze it in there. LOL.
.
Is it possible to turn off the step down ? I may water cool it if it can be turned off or extended.

I would not advise buying this light, the beam is almost unusable. The counter-bore for the led is off center and tilts badly causing the led to shine off center of the reflector. the further away you shine the worse it is. I’m sure this could be an isolated light. This pic is the best I could take and this looks good compared to the actual view. The hot spot is not round.
