The popular RRT-0 has been updated to be an even more versatile flashlight, with a rotary ring that allows for infinite brightness ramping, from 0.003 lumens all the way up to 550 lumens with lithium batteries. The LED is now a CREE XM-L LED, which gives even more output and a wider, more floody beam. The included extender allows the use of AA sized batteries as well.
