I figured this would get more replies... anyway, I ran to Ikea on Saturday for some AA NiMHs (never do this this close to Christmas; next time I'll order online for pickup rather than actually go in the store), dug some 3xAA to C cell adapters out of my battery box, and picked up the NiteIze "4005778 High Power LED Upgrade Bulb for C/D Flashlights, 74 Lumen Bulb Pure White" off that certain river themed e-commerce site. Put all that in the Bright Star after cleaning it all up. Works great. Can't tell whether it is preferable to my very early LED Mag-Lite or not (haven't been able to do a side by side because while playing around I managed to insert one of the cells backwards so I have to wait for them all to charge up again), but for an emergency light to hang by the front door it's fine. So, there's one option for a drop in that replaces the original bulb. Amazingly, both lights worked with their original PR2 bulbs after a good cleaning; apparently the bulb contacts in the Bright Star were keeping it from working originally and there was some light corrosion inside the tube from leaking cells that I scrubbed out. The tailcap spring in the Eveready needed to be cleaned as well, but that light appears NOS and unused after a quick polish.
The only other real option other than the Nite Ize that I saw was the Dorcy "30-Lumen 3-Volt LED Replacement Bulb (41-1643)" has anyone used that one and have any opinions? I'm guessing if the lumen ratings are comparable the Nite Ize is the better choice.
Anything else I should be looking at? Everything else I found searching was the usual Chinese "brands" that I'd never heard of, although the reason I'm posting is in case one of them is really putting out a superior product.
(sigh) now my $2 flashlight is a $30 flashlight, not sure it's really better than a brand new $30 flashlight, but it is cooler looking...
