the ML1 CX stands for Milkyspit L1 Cree Xtreme.
There have been a few versions of the ML1, but this is one where you get to keep most of your parts stock.
you Start with an L1 Cree, you can either buy one and send it to Scott (Milkyspit) or buy one from him.
Next, Scott will unpot the head, and replace the driver with a mad-max driver, which according to his latest PM, will drive the LED at 700ma on primaries, and 900ma on RC123A. Needless to say, this makes it a heck of alot brighter.
next, Scott will recalibrate the tailcap's resistance, in order to achieve lower beam. This is done because increasing the drive level, means that the low beam will also be higher then stock, Scott increases the resistance so that the low beam will be about the same as the old style L1, 2-5 lumens. If you want, he can recalibrate it even lower, around 1 lumen, or less i believe,but this will cost extra, as it takes more time and testing to get it exactly right. I did not opt for this, as i think 2-5 lumens is fine for a low beam. this 2-5 lumens is based on the L1 cree's low is 10 lumens.
Bonus, you get a variable focus light, by loosening and tightening the part of the head that contains the optic.
in short, you get, exactly what the L1 Cree should have been, but isnt.
Milky also offers boring for the body if you need to use certain rechargables.
There are quite a few other versions, such as a floody L1, reflectored L1, L1s using SSC LEDs, and a short version, etc etc, again its almost fully customisable, all you have to do is PM scott, or email him.
Please do note however, that scott is a busy busy man, and may not always get back to you straight away. Like for instance, my L1 CX has been about 2 months in the making, from first contact, till the point i sent it, to right now im waiting for it to get to him. But, i think its worth it.
