This:
Some of us have been drooling over that one for a while 
But if you read the questions on site, they are figuring 46-48W draw and 3,800 lumens: needs a major mod. And looks like it could sink the heat with that big of a head and fins.
Yep, it'd be a lot more attractive if there were good drivers for it.
I love my j19, any reason not to fit the ios 7*xm-l 3a/emitter driver?
Great output in a pocket-size light!
no one have this flashlight jet?
I do!
Emitters are wired 6s2p, driver looks to be the same as AK 90, delivers around 1A/emitter, head cavity is HUGE, very heavy built everywhere. If any 12x head can sustain 3A/emitter, this must be it! This one cries to become the home of a better driver (or drivers J) )
Downsides: Needs more than three cells to work with a high power driver, I`d say eight or nine or ideally twelve 18650s to keep input current down and runtime up. Must make adapter, tube and carrier :~ . Another flaw is that the head cant be opened without twisting the led wires. And oh, it is kind of heavy, but that wasnt really a bombshell.
