Adapted to 18650 and given a bit of a trim job where possible and I might consider one of these. As it is, it's too big for convenient EDC, so make it much more capable (18650 goodness) and it's utility will increase tremendously.
+1 on this. Since the light is on the big size for EDC getting 5 times the runtimes with an 18650 is worth the increase in size.
Add a warm white led and this looks like a great mid sized camping light

I'm pretty sure I'll be saving up for this one.
