This may be a tough order, as I'm kinda fussy, but here it goes... ! I'm looking for a simple, indestructible (machined aluminum), long battery life, wide spill, single CR123 light that I use to roam around w/o wrecking my night time vision. Not looking for multi-functions (Quark, etc) settings for this kind of a light. To conceptualize, something like an Inova X-5 (one of my fav lights still) but single 123 and single LED. Thanks for your help!
