All the torches shown below are running lithium batteries and if the zoom-able ultrafire torch was even "Just" as bright as the old Fenix TK35 (love this torch) (suposedly 680 l) I would have been happy but it isn't much brighter then a little Sipik with a tiny little cree bulb of some sort.
Anything I can do to improve this light other than replace it?
Very disappointing considering all the good comments about these lights.
