wah piang .... some of you guys are SWAT team members or what ?
why would anyone need a tactical light for ? ....... 
I have a couple of pelican torches in my tackle box, and a petzl
head lamp for night fishing ....
and another couple of underwater kinetics diving lights for
night diving ....
because, some of us take part in mil-sim skirmish scenarios? You
can call us "replica SWAT team members"
