This event is not a safety issue and typically occurs when the LED Strip load falls below the threshold of the driver design limit, which will result in a minor capacitive discharge in the form of the LED strip momentarily "blinking" or "flickering" when the power is turned off. When cutting LED strips KITS, it is always important to calculate the remaining LED load to reconfirm its compatibility with the existing driver, as driver changes may be required with moderate reduction in loads.
