Well, you could get the TerraLux MinStar2 conversion old review here .

This one is simple - remove bulb and reflector, plug in module like a bulb, add new reflector, screw back together. It is much brighter than the Opalec NewBeam. I have one of each and like them both very much. The MiniStar2 is much brighter than the NewBeam and fits ANY Minmag, old or new.
