Yeah, if the technology doesn't take off, its a good thing to have. Obviously 500 lms and two and a half kms makes for an extremely focussed beam with little or no spill. I also have a K75 and its an absolute beast, BUT, its certainly not as handy, size wise, as the W30. I reckon as far as a fox or rabbit goes, you'd stop 'em dead in their tracks with that light. The one thing I see with LEP, and its early days for the tech, is that they may not make a good mid/flood beam, with the lumens they put out. Who knows down the track a bit though. A very interesting torch to own and use.
