Opinions, sources, LED conversion 2-D cell Maglite bulbs?

Well the project has come to a VERY successful end, but I would not do this again. I paid 10 bucks for the light, which worked, and 15 or so for the TRlife LED bulb, so I have 25 or so bucks into a light I can buy new--with LED---for 33 bucks. So I did not save much. Also the thing was intermittent. The way the socket is built, it slides in a plastic housing to focus when the reflector is turned, via a rotating ramp like device on the reflector. The ground for the lamp is a sliding contact on the side of the lamp "receiver" and evindently that was not optimum. I fiddled around thinking about adding a ground wire, and that is a tight "deal," but I finally just bend the flat spring some for added tension. The thing REALLY works well. The light is not near as blue as my factory mini-mag AAA LED, and when shined at a tall tree up the block, hundreds of feet away, it does a good job.

So I'm happy, but if I knew how close the price would be to new, I would have left it lying there.
