Due to the lithium batteries inside the LED fan tubing if the main power button on the LED fan strip is on but the remote has turned it off this will still use and drain the battery requiring another charge. Remotes will not work properly if the LED fan is not charged correctly as this greatly affects the signal to the remote. Leaving the main power button on can also be affected by other RF signals. As some may be similar this may cause the fan strip to turn on randomly. This is why it is always recommended to turn them fully off using the main power button on the LED fan.
