I found this headlamp in a junk box, it doesn't have name on it. It is pretty heavy, runs on 4 x AA. I thought that I could use high power LED drop in but the reflector seem to thin and and to wide. Is there any LED drop in that will work for this reflector? Is there any LED drop in that will work with 4 x 14500?
Thanks!
I think you're out of luck with that one. You'll probably need a custom adapter to fit a P60 module into it, which would have to be hand made specifically for that light, which will easily cost you more than a brand new high end headlamp. And to run something like 4x14500, you'd probably have to custom order a Nailbender or something like that, maybe a Veleno... not sure.
Sad but true fact is that you'll get a lot more for your money just by buying a new Spark, Zebralight, or something else, maybe a PT, BD, or Brunton.
