Bingley,

There are a lot of good lights out there. When the CERT I belong to is activated, a Nitecore SRT7 goes on my belt next to my multitool. While it's very versatile and there are a lot of things to like about it, there are better throwers in that form factor (1x 18650 or 2x CR123A with a big head).

For me, the performance gains from using 18650 rechargeables means that all of my larger high-end lights take them. But there are still a lot of options. What form factor are you looking for? Are you looking for big throw, a wall of light, or something in between?
