Some time ago, I bought a 2 cell Pro Series 3 low dome PR base bulb for 2 cells (3 volt). I got it for my 2D Mag. It turned our to be dim with a pea green corona (from side emission) in that light. It also flickered every time the Mag bulb stem (mount) moved. Dimming and brightening. It drove me nuts, since there was no sure way to get it to be bright and focused at the same time. So I put it back in its case and put it with my other bulbs.
Recently, I came across an old Radio Shack metal mini that I got my dad. This light is sort of like a minimag, except that it has a different style head, and uses a PR-4, K4, or KPR104 PR base bulb, and 2 AA batteries.
I thought to myself: I wonder if the PS3 that I have would work well in here, using a pair of Lithium AAs??? I just tried it and left it on for a while (to test for overheating). I get a nice bright, smooth focused beam (smooth reflector), and most importantly, I no longer get the pea green corona.
I tried it in my PT Solo with both reflectors and didn't get the focus I hoped for, though maybe the new HD version LEDcorp has will do well there.
Well, at least that $40 bulb will no linger go to waste, sitting in my incandescant flashlight bulb box.
Note: the Radio Shack Metal Mini had 2 versions. The original version could be used as a candle, while the final version could not. This is the original version.
So, if you have the same situation I had, and have one of these metal minis sitting around, put the 2 cell PS3 in it and feed it a pair of lithium AAs.
