i popped a seoul star in mine and it is fantastic. no changes neccessary to the reflector or anything. just a nice easy doubling of output and with the super 1 watt's great regulator!
I put a Cree in mine. The reflector needed re-working, as did the black plastic spacer. At the time I was thinking "this wasn't worth it, it was a good light to begin with", but after getting the fruits of that trouble I see it was worth it. Not fantastically brighter, but better runtime, particularly with depleted cells. The beam is not as smooth now, I did not take the time to get the reflector perfect.
I'm looking to do the same with mine. You could try a Lux III, same architechture and pretty cheap, and you shouldnt have to mess with the reflector. Second the cree or seoul though, then you'll have basically the same as a lot of the dx lights, but I don't know how the lack of heatsinking would be.
LED_Thrift, ginaz,
how does it act with those since there really is no heatsinking?
The Seoul provides a perfect beam if you just sand the vertical part of the reflector's hole.
This type of light is so easy to mod that you can change stars whenever better bins come out. And at a constant ~350mA the lack of any heatsinking is not a big deal.
It seems to heat up about the same as the original, but it's hard to remember exactly how it used to be. I have to borrow back the one I gave away and do a comparison.
I took out the large plastic sleeve and made an exact replacement out of aluminum. It needed a delrin insert through the middle to isolate the positive lead from the battery. On lithium ion and Cree emitter, it screams. With such a large heatsink it only gets slightly warm.
