That chart helps a ton. Where do we find these charts?
I want to confirm a few to make sure I understand
1.) The xm-l2 above would pull 8 amps. The voltage on the battery would sag of course, let’s say to 4 volts for the sake of this example, at which point, the LED would be pulling 7 amps. As the battery voltage dropped, so would the amps being drawn, and therefore, lumen output as well.
2.) if I built a triple xm-l2, the initial amp pull would be 24 amps. This is higher than the continuous amp discharge of the battery, and therefore, the battery at this point would be limiting (struggling) to keep up with the demand of the LEDs. Soon, voltage would drop below 4 volts at which point the battery may be able to keep up with amp demands from the LED? Once again, lumen output would be falling throughout the process.
