Here's an observation I had with my PAL Gold. I put an old 9V battery in it, and there was no change in brightness between the high and low settings. The battery had 5.1 volts. Another battery had 6.4 volts and did show the expected difference in brightness between the two settings.
Since 5V is still more than the LED needs to run at full brightness, did the PAL fail to shine brightly due to the losses in the circuitry or is a battery that low unable to provide the amps needed?
Just curious.
