More lumens. Throw is based on how well the beam I focussed.
I have an ultrafire wf502b noticibly brighter than my lenser P7 which is only 200lumes, however the lenser has a focusable head and can throw that light a lot further than the ultrafire, the UF will light up whole field, the P7 won't but can be focussed on a tree in the next one, what's the budget? You want smaller size?
