Watch that ROV 2AA that Light Sabre linked, I have one, and unless they changed them, it is a bi-pin bulb, not a PR. The 2-D is great, though. ROV also makes a bigger, focussing version of the 2xAA Industrial, which does take a PR, and I put an SMJLED in one of those. It did have a bit flakey clickey switch, though, but I was able to take it apart and De-Oxit and grease it, so it works great now.
I actually like the Energizer Industrial the best of all for these bulbs, the simple $4 one at Home Depot, not the K220E one. Nice beam, reliable, easy to access to clean switch (just pop of the slider), and plenty strong body and threads.
The old Walmart specials are back, by the way. They are sold in eight packs under the Husky name at Home Depot, for $10. A bit more than the $0.84 that Walmart sold them for, but not bad. These won't take a big hit without coming apart, but they usually don't break, they just pop the threads when dropped hard, but not quite what you were asking for. The crazy thing about them was that they were cheap, and made a dang near perfect beam with these bulbs.
With respect to the bulb durability, I think I have every generation of these made. The later Sandwiche Shoppe ones do draw more power from a given set of cells than the earlier 4-die versions, and have a warmer tint to them. The tests that Newbie (retired from CPF) and another member ran were at 200 mA constant for the SS version, and 150 mA constant for the older 4-die version. All I can say is that I select either NiMH or used alkaline cells for the bulb that I am using that only measure between 100 and 120 mA draw at the tailcap. I have not had, nor do I expect to have any detectable loss of brightness when driving them this way. Depending on the bulb, if I use a fresh alkie or a lithium Energizer, I can easily see 150-200 mA draw. I do not, however, see enough increase in brightenss to justify torturing the bulb at this level, and choose something else. One of the great features of these bulbs is their ability to extract many hours of usable runtime from otherwise spent alkaline cells, and they will last darn near forever while doing so. The above tests were run on a bench power supply that never dropped the current below the set starting level.
