So when it's plugged in while a power cut and the switch is on on the switch board, the bulb glows with 50% brightness which is kind of sufficient. When the power is restored it glows with 100% brightness and the charging begins simultaneously. But when there is not power cut and then u switch it off from the switch board, it stays off for a few minutes an then turns back on glowing with backup power, while u were trying sleep. So u can either keep turning it on and off the whole night or u'll have unplug it from the holder and then sleep.
