I've seen, and indeed tested, several LED torches from different manufacturers, which have claimed to be "HID Killers". Not seen the LED yet which can match an HID in terms of focus or penetration. The proteus is a great torch. The LED16 supposedly puts out twice the lumens, but I bet you don't get the pencil beam focus of the proteus, and its certainly not the equivelent of one of the big HIDs. Whatever the blurb says, this design is not preferred by technical divers for signalling purposes.
