surefire 3v batteries
dorcy LED flashlight
i have a LED dorcy flashlight that runs at 110 lumens with 3 AAA batteries. i know a AAA has 950 mah and i want to know how it outpreforms my surefire G2 LED at 80 lumens on 2 3v cr123a batteries. i know it has to do with the efficiency of the bulb which has a yellow tint to it so i can run on the 4.5v source. finnally i want to how i can tell how long a battery will run at a surtain voltage. or if you need to know the wattage and how do mah,volts,watts interweve in this subject.
You need the wattage or the current before you can make any comparisons, and even that won’t tell you how long the battery will last unless you have the capacities of the batteries.
If you know the current, you can multiply by the voltage to get the wattage.
To find the actual capacity of the batteries, get the amp-hr number, which may or may not be available, and multiply by the battery voltage to get watt-hours.
With battery capacity in watt-hrs, and lamp power in watts, you can divide to get hours of life.
One problem is that amp-hr capacities are only approximate, and vary with current level.
