Shouldn’t be a problem if they use XP-L HD or XP-L2 emitters on V5 or V6 bins. Even the Emisar D4 can pump out more than 4k startup lumens.
Despite the light looking very interesting, I won’t buy another Manker due to the awful UI. Grouping turbo with strobe modes is extremely annoying. That’s why I never use my MK34 despite I like the design so much. I should have paid more to get the MK34vn, which has a UI to make the light usable.
You are telling the world in various threads that you will not buy any more Mankers until they ‘fix’ their user interface, so that makes me feel inclined to tell the world that I fairly like the Manker UI, they really did a lot right I believe, when in use it works supple, you can tell that they tested it out and finetuned the timings, what even high end flashlight manufacturers sometimes fail to do (i.e. Jetbeam E40R :person_facepalming: ). They just made a choice that you do not like and there will be others who will be particularly happy about turbo in another group (but ready accessable). Personally I’m neutral about that choice.
