I have a convoy c8 with a dedomed XML u4, which will be doing approx 60kcd throw. Its a great wee light for close/medium range, happily shooting rabbits at 100m and full view of behind the animal for a safe firing zone. Cost $30 incl mods by someone else. I have got on order a maxtoch 2x, 360kcd so 1200m ‘range’ and looking forward to getting that out. These are $95
