Re: MilkyModded Mr Bulk VIP
Depending on which tail cap it has (Kings crown Kroll, flat twisty, etc), activation is either by reverse clicky or twisty. The head has a 3-way switch for low, high, and "boost" output. I'm not sure that those are the correct names, but they describe the levels pretty well. Boost is brighter than high, but there's a much bigger difference between low and high than between high and boost.
It's roughly the same diameter as the Cub (with the stock head, which this is with the 17mm reflector), but longer - how much longer depends on which tailcap it has.
There's a picture

It can be safely driven with a CR123A or 2xAA Alkaline or NiMh (with the correct battery tube). Some folks have used R123's, but the last I heard, whether that's safe or not is depedent on the individual light. Sometimes it's safe, sometimes it's not. I've stuck to primary 123's and AA NiMh in mine, just to be safe. More info on R123 cells can be found
here (note the builder's warning in reply #9 of that thread).
Like yaesumofo said, if whoever gets this light is lucky enough to locate a 3" Big Bulk Head for it (no small task, btw), this should be a very serious thrower. Even with a LuxIII, mine is.
I've thought about upgrading mine to a SSC, but the truth is that I probably wouldn't carry this piece of history as I have other lights for EDC, so I'm keeping mine stock. Having said that, I'd love to see some beamshots.
