So I purchased a Zeus X and have been using it successfully for a while now, but today I noticed that the diode is not burning anything. I tested it on my hand, and the dot is barely warm. It seems that im not in low power mode, as I can hit the button to switch into low power mode and I see the dot become slightly less intense. Im wondering what could have happened. I don't think I ever exceeded the duty cycle, but If I did I assume the diode would simply die. Not sure what to do here. Any help would be greatly appreciated.
