There's lots of information on their runtimes and outputs here.... http://www.candlepowerforums.com/vb...Malkoff-Runtime-Graphs-CR123-Alkaline-Comparo Use one with a decent host and you'll have one of the most rugged lights out there. You can get a SF 6p bored for 18650, or host from Solarforce and of course Malkoff. Malkoffdevices.com will show the various models. P
