I think Justin Case is getting ready to sell a regulated Mag623 in a 4D mag host. It's run off of 5xIMR 26500s. I have one that he built, and it puts out a cool 6800 lumens for the full runtime, since it's regulated at 15.5v and putting out 160 watts. It's unbelievable, once you turn it on in your hand. I don't have any beamshots, since I just got it. It's basically the mother of all mag build incans.
A key advantage of this setup is that you can swap out the bulb for a 64440, which will give you a full 2700 lumens. This is much more manageable, since the light and heat of a 64623 lamp really makes it just for show. There are couple of other bulbs you can put in it for even less power, if you need more runtime. I'm going to try a Hikari JC-5033 bulb, just $2.25 each from Amazon, for a 1600 lumen, long runtime version.
This is an extremely versatile light. The regulation means that the light is constant throughout the run, with no dimming whatsoever. It has a low voltage warning, so you know when your light needs a battery change.
The 4D maglite is actually very light with 5 IMR cells in it, it feels as handy as a 3D maglite with alkaline cells in it.

everything yal said was pretty much just french until this guy, Hes giving me size, runtime, and lumen specs which is something that i can understand.
Somebody mentioned my quote about how " i cant solder this stuff together and test it", hes right, shamefully I CANT!
Im very interestd in this rig though. I would love to know what the projected price and availability are. I only like LED's becuase they throw out that nice white natural light instead of the yellowish light that incans do. Its easier for my brain to discern shapes and colors and stuff while under stress when using a LED. Also, I hear that incan bulbs wear out quick if you dont let the filament warm up before you turn them off, like you have to run them 3 seconds minimum when you turn them on. That doesnt work for clearing back yards and fields and stuff when you dont want to leave the light on all the time and be standing behind it.
The 4D is a little big, but i can learn to deal with it if the thing will run at a good manageable 2500-3000 lumens.
Plus the old guys tell me they're good clubs.
