UN-Surefire
I tryed many lights out there on the job,(LEO and overseas)and I must say,Surefire lights are crap...i have 2..the bulbs dont last
when you drop it,and the bulbs dont last when you dont,plus there expensive..and on one I had,the bulb actually melted the lens.It doesnt matter if they have a lifetime warranty ,or they will send you a new lens in 24hrs,or that someone carrys spare batterys and lenses,when the SHTF and your light aint lit..Its your life and I wouldnt have it depend on a UN-surefire
For now I only carry Streamlight now,(mainly the stinger),they are the best in my opinion,you can drop it,throw it,hit someone over the head with it(j/k) and they still work...
Surefire has the colorful advertising,thats about it
