You are right, but I think that from Nitecore look for a classic rear switch, without parasitic consumption and that allows to maintain a very small size for a flashlight of this class. The design is simple and the price for what we are accustomed to in Nitecore is very good.
Anyway if you leave it to someone, and you tell them “this is the button”, they will be able to remember which is the switch (there are only two to choose, it will not be very difficult for them … 
How difficult is it to swap emitters on the Nitecore MT22A?
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:
