No problamo!
I was going to add Fenix which I think is the brand in Galls.
Galls also has a protection-white light you can re-charge with a USB port.
Other good sources include;
www.natchezss.com www.blackhawk.com www.policehq.com www.qmuniforms.com and
www.uscav.com.
Some other white light features you may watch for are;
anti roll design(if you drop it or lose it in low light)
duel or tailcap operation(helps with firearms or if you need the device one handed)
water-proof(not water resistant which means it can still &@#% up in the rain)
compact size
CREE or LED type light source
a defense type design so you can use it as a weapon if needed.
You may need to tear a big chunk out of a violent attacker or bust a huge wound open in his or her mellon.
It could be ugly but war is Hell or so I've heard.
Stay alert & 3D...
