Back-Up Power for Any Light Socket
The Mr Beams® Bulb Adapter stores power and lights up lamps and bulbs during a power outage. Wireless Environment’s patented SwitchSense® technology allows the Bulb Adapter to detect a power outage through the light switch, enabling it to power a lamp for up to 3 hours during a power outage while being controlled by the switch.
The Bulb Adapter maintains its charge through line voltage. When it detects a power outage, it reads the position of the light switch and turns on only if the light was already on. If the switch is open, the Bulb Adapter waits for the light switch to be turned on to activate.
