Low Battery Warning:
The light flashes 3 times when the power capacity reaches 10-5%, and repeats after 5 seconds. If the current mode is Green beam, it switches off after the flashing. If the current mode is White light, it switches to lower brightness level after the flashing, and switches off automatically when the power capacity is less than 5% to prevent over-discharging battery.
