Olight S10 Pocket Flashlight (400 lumens) - the S10 (and rechargeable S10R) are my favorite compact flashlights for everyday use. The magnetic base makes these great for home inspectors, contractors and mechanics for use in the field or shop. I've even attached it to the fender of my car for an emergency tire change at night. There are 4 different power settings, from 0.5 to 400 lumens. The light will also tailstand on a flat surface for use as emergency during extended power outages (360hr runtime in the 0.5 lumen moonlight mode). The S10 takes 1 CR123 battery (available separately).
