I have a 3xC cell Sabre light, that has a 30 lumen incandescent bulb/reflector in it.
It's been my back up for years. Aways works , reliable dependable etc.
I've ordered a cree 200 lumen drop-in module from DealExtreme as an experiment.

Just wondering if anyone has tried this with any success.
I estimate using 3 alkaline c-cells usable range should be 4.5 vdc down to about 3.0 vdc.
Alternatively I can run 3 Nimh c-cells at 3.6 vdc.
