Been reading this board for a while which led to some tinkering last night, I have some PR LED corp bulbs for 3 and 4 cell units so I wanted to see about putting a 4 cell(6v) in a UKE 2L(6v). I first went to put my new spare bulb in my UKE before I went to sacrificying my old one and presto the new one was NO GOOD. Well enough I sacrificed it-pryed the plastic base away from the bezel and brass looking body easy enough, then had to break out a black plastic inner ring before I could try to fit the bulb. Needlenose plyers tugged most of that out of there. Various scraping tools got it down flat to approx. correct depth, then drilled bezel to fit bulb. PR bulb fit in there perfectly diamater wise, took a little work to get the depth right. The negative wire on bezel was kept intact and with a slight filing on the PR flange it actually is a perfect pressure fit to hold contact against the wire- I didn't even have to solder it, which is cool cause I'm not sure what temp iron I'd have to use anyway. Works fine, not the greatest beam quality but a superb survival type light. Beam has dark center probably 18" at 10', other than that a wide beam similar to a TurtleliteII but not as bright or diffuse. But a good no brainer conversion.
