How to Troubleshoot the FlashTorch and FlashTorch Mini:
How long was it initially charged? It should be for about 3 hours.
Is the LED on the switch ON? If it's blinking, that would mean it's in lock mode.
This happens if someone tries to turn it on while it's charging.
It will need to be turned off and the power cord will have to be unplugged.
Cycle the modes of the power switch to turn it on.
If the LED is constantly on, it means the battery power is operating normally and it could either be the bulb is loose and/or broken.
