does this look like a Suitable host?

China has been making that water resistant "police" laser for a while:
$33.58 - 30mW Police Flashlight-Style Green Laser (CR123A) - Green Lasers
I think the second host would be a better laser (for the head-dissipating fins) and I remember seeing recently that a forum member made a laser using that exact same CREE host. Maybe they still have the dimensions of the heatsink.

ahk cheers ash. will have to try and find out who made it so i can get the dimensions for a heatsink. and cheers for the link. looks like i may just turn the first host into a standard low powered red, and use the other host for my green
