Run-Time Plot - Sapphire 1w LED 3xAAA

[Roy]

This runtime plot is for a "Sapphire" 1w LED flashlight using 3xAAA batteries.

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 in mVdc and is equivalent to 1mVdc @ 1Ft = 1Fc @ 1Ft. The horizontal axis is 30 minutes per division.

Be aware that your actual battery milage may vary from that indicated by this runtim plot.

3xAAA Alkaline Batteries
The runtime to 50% max brightness = 2h 14m

3xAAA L92 Lithium Batteries
The runtime to 50% of max brightness = 3hr 1m
