The
Elecstor 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 4 hours of backup light.
