This runtime plot is for a Vortex TC-1 that is using a single 1w LS led and one Surefire CR123 Li battery.
Equipment used is a Extech Mdl 401021 Light Adapter into a Radio Shack 22-805 multimeter with a PC interface that is using ScopeView software (V 1.08).
The vertical axis is 40 mvDC per division which is equivalent to 40Fc @ 1Ft per division. The horizontal axis is 15 minutes per division.
Be aware that your actual battery may vary from that indicated by this runtime plot.
The runeimt to 50% max brightness = 1hr 35 min.
