Streamlight sidewinder 3 - Streamlight Sidewinder Compact III User Configurable Model AA/CR123A 275 Lumens LED Headlamp

Sidewinder # 3 is a great upgrade to the Original and # 2, much brighter overall and i'm not sure if streamlight recommends it or not but 2 and 3 are dual fuel with AA and CR123 batteries but to me its tri fuel with the ability to use AAA, of course power output is less but it works and I Love the hook and loop additional part for mounting almost anywhere beside the helmet mount or the Head strap
