I have a Luxeon star 6 watt led torch, thats bloody bright, trouble is the batteries bloody dear! it takes 3 CR123 and they last a few hours, and its no good buying cheap batteries off ebay, they last even less.
first time i got caught without batteries i bought 3 at the supermarket without looking at the price till later........£18 bar 3 pence
in general i prefer my Pezl head torch that takes AAAs its not as bright, at 1 watt, but still illuminates my whole garden better than the 2x80 watt PAR floodlamps on the wall
that wasnt cheap though, £50 ish.
