Sengled Everbright 9W Bulb with Rechargeable Battery

Equipped with a built-in rechargeable battery, the Everbright 9W Bulb from Sengled is designed to keep your house lit during a power outage. The bulb uses smart circuitry to sense a power outage, and it will then automatically continue to provide illumination using power from an integrated lithium-ion battery. The smart circuitry is able to detect the difference between normal on/off operation and a power outage, so that the light will not automatically turn on when you have intentionally turned it off. Furthermore, once your power comes back on, the battery will automatically recharge using the bulb's standard power supply. The Everbright Bulb is a 9W lamp that emits up to 500 lumens of light. It features a color temperature of up to 3000K, and the bottom of the bulb is an E26 light base for compatibility with most light fixtures.
