What I wonder is what is the "burn" time of the torch that is in the video? There seem to be a lot of these small high power torches all over ebay, usually with some form of rechargable battery. How good they are is anyone's guess. I bought one and to say that it was a bit of a disappointment for "burn" time would be an understatement.
I use the Led Lenser L7 because they are affordable and also use them as a gun light on the .243 I have a few of them and would have to say that they haven't failed me yet.
I should imagine that the big LED Lenser is a pretty gucci bit of kit. It's just rather a lot for a torch at £280 / 2600kr -
