I don't see the appeal. I'd rather use the Solarstorm K2 or Trustfire TR-A9-2. The cells for those will cost about the same or much less, but will have more power.
I was referring to Erum`s post.. (not saying that this any good or whatever, just replying to the post above mine)
He said it has No modes, and that is Too expensive.. I don`t think so.
I know. And you're right that the flashlight itself isn't expensive. The battery configuration makes it expensive though. Three 14500's provides less power than a single good 18650 or 26650, but costs more. I would consider a 3x14500 light if I came into a free windfall of new 14500's though.
I do tend to agree about 14500's making the light less attractive. I do like that it will run on Ni-mh's and the Rook does have a very beautiful beam pattern. If you can bore out the center just a tad, an 18500 can be used. These are $1.50 each and seem to be as good as new.
