Hi
I'm looking for nice machined heads for a homebrew bike light. I'm hoping to use some of the new Seoul or Cree LEDs, but I don't know what's available for them yet. I'm hoping to have an output of around 250 lumens. I can handle the electronics and batteries, but can't machine.

Thanks for any info! I've been reading for a few hours now and am thoroughly overwhelmed! I haven't stopped by CPF in a couple months and it's all changed, looks like a whole new generation is available.

The KTronik looks cool, but it's a bit big.

I'm thinking that I could buy a pair of small Cree flashlights, drill holes in the bodies, run wires to battery packs, and seal the holes. Does that sound realistic? Would the beams be too tight?

minimagLED`s are cheap as chips, i`m suprised nobody has come up with a custom bike light based around these ...
I have a 3/4 built 2x mini-mag based light I plan to use for a headlamp (for biking). Its focusable (to an extent) which is nice. One minor complaint about the mini-mag is that the head kind of wobbles back and forth a bit more than I'd like. (Maybe some teflon tape on the jthreads might help?)

I think a better way than modding multiple small lights would be a MagLite head.
3 or 4 emitters fit in with no problem, MUCH space for a heatsink and this can be press fitted (better heat transfer) by the front cover thing, ultraclear/antireflective glasses widely available, whole light to be found in scrap sales or in a color You like for a minor amount (whats a D-Cell now at Your place?) and finally: only one hole to be closed and You could put switch and power jack there.
Overall not very big or heavy
