so got my L2m today..8 days (not business days) after ordering it (insane)..tried my 16340's..white solarforces would only manage 880 mah..grey trsustfires did 1550mah..my trustfire flames did 1750mah which is what I have my nanjg driver set at (1700mah)..so far so good..nice little host and reg size host also if I want to use 18650's..
I did not know L2m was upgraded but from pic I can clearly see the crown is either new or borrowed from L2P.
Logo is also new.
I believe these can only be bought as empty tube set, with extension OR as a ready made flashlight from s-sales.
