OWLTAC is a flashlight company that has started a Kickstarter campaign for what they claim is the first dual independent, selective battery powered flashlight, the A1T Endure. The A1T features an aircraft grade 6061-T6 aluminum body with type III hard anodizing, concealed o-rings, a belt clip, and lanyard holes. It is IPX5 certified, and drop rated to 1m.
The most unique feature of the A1T is its dual-battery operation. Powered by two CR123A batteries, the A1T only draws from one battery at a time, allowing the user to switch to the second battery when needed via a toggle switch; this feature has been compared to an independent backup battery on an aircraft system The A1T outputs 200 lumens for 1 hour on a single CR123A on the max setting, and 16 hours on the 20 lumens low setting; the above image represents the run time with two batteries.
