Good host for o-like modules?

[o0ICE0o]

I am looking for a good host for a green o-like module.
Module:
3pcs Green laser module/5-10mW£*>5¡«500mW green laser module£*>Laser&lighting products£*>www.0-like.com

Will this work?
DealExtreme: $10.70 SmallSun ZY-C64 Cree P4-WC 100-Lumen LED Flashlight (2*AA)
Are there any beter ones?

Also, to make shure; but the o-like modules are case neg.?
Thanks.

case positive

As many hosts are case neg, so can I just put the bats in backwards?
