I do not know, seems that the head bezel have watchmaker notches for removing the piece
The Nitecore MT22A have a die cast design in head for evacuate the heat, at high mode get around head section 58ºC-60ºC (Celsius degrees) in 10 minutes, after that start a little step down and the temperature decreases slightly.
Thanks trevi_lux, I did see some threads at the bezel in one of the photos but not sure if it’s glued down.
3 zebras here now…
One zebra for me,sc5c mkII
I received acebeam x60 xml2 dedome modded and Nitecore concept 1.
Very nice NL, what is your opinion on the 1? Looks a pretty neat light, just not sure on the UI and battery drain/unable to lock out.
It’s great… I was using Sony vtc6 and voltage was 3.4 and it’s still light up… It’s very bright… I will take beamshot tonight… user interface is easy… I bought this from banggood group buy… so it’s cheap…
At 3.4V you better start thinking on charging that battery 
I’m somehow dissapointed a bit with the Concept 1. Don’t get me wrong, the flashlight is solid, good performer and have a very “unique” look, which is specially hard to see these days. But imho Nitecore could have done a much better job, specially with the switch design. Also I’m not very keen on having to switch off and then on the light to change a mode. More details in my review here. 
Thanks for the info NL and Upz(great review/pics to)
I know I messed up… i got very excited. I thought they are fully charged already… it turn out my vtc6 are brand new… I will not do that again…
Lumintop Tool CRI. For me, the ultimate AAA neck light design-wise.
Guess the light! 
No idea. I’m gonna go for a vague guess and say it’s a 4x18650.
Also, can you please resize? These gargantuan photos wreak total havoc with mobile device browsers.
Resized! Sorry, I am used to forums were pics get resized automatically.
Not god for 4x 18650… just the half 
I was thinking about the SRT9, but I couldn’t find the button detail…
Oh, it’s not a button! :+1:
Thanks, my man :sunglasses: :+1:
Definitely has the same finish as previous Nitecore Die-cast lights. Looks like the power indicator on the SRT9.
BINGO!
