i think you can get a Bad Boy drop in for a Minimag for around that price..
then again, for about $15 more you could get him an Elektrolumens Blaster 3.. which is one of the greatest luxeon lights available, in my opinion.. especially with 24 hours of bright runtime on three D batteries..
i'd throw the Streamlight 4AA ProPolymer 7LED into consideration too.. very bright output and alotta runtime.. however it's not a luxeon, i dunno if that has anything to do with your decision..
the Pelican Sabrelite Luxeon looks like it has great output, and it's waterproof..
it looks kinda clumsy to use tho with the gigantic clip on it..
the original Sabrelite is an extremely popular light around here with fishermen tho, so you know it's tough..
so there's a few more ideas.. since all these lights have good to blazing output, i think you can weigh some of the other features of the lights in..
but i think the Sabrelite Luxeon would be a good light for him.. going with that would be great gift!
