How far do you drain your 123's before changing them in your Surefire's. I am trying to figure out how to get the most life out of mine without risking blowing the bulb from draining them too far. What do you use the semi drained 123's for, if you don't have an LED lithium light.
And most importantly, before I buy an E2o, will the regulated A2 allow us to drain the 123's all the way without blowing the lamp, vs half to 2/3rds of the way with the E2o?
