The Redisson Emergency LED bulb stays on in the event of an unexpected power outage or load shedding. The emergency bulb is a direct replacement for a standard bulb, and the built-in battery will automatically charge when the bulb is switched on. In the event of a power outage, the intelligent light control automatically reduces the brightness of the bulb to ensure that the battery lasts as long as possible, and gives you 6 hours of backup light.
