Get up to 12 hours of battery-powered lighting with the Feit Electric Adjustable White Rechargeable Battery-Powered LED Bulb. Reliable and rechargeable lighting, this bulb goes from a standard bulb to battery power during blackouts and loss of power. Battery-powered bulbs are perfect for locations that have frequent storms or power surges. Take them outdoors as a camping light or flashlight. Backup bulbs fit in standard E26 fixtures and work like a regular bulb until the power goes out. During an outage, they switch to battery power. Turn them on/off from a button on the bulb. With the included remote control, you can further customize your lights from up to 15 feet away. Adjust the brightness and color temperature (2700K, 3000K, 3500K, 4000K, and 5000K). Conserve energy and let your light shine longer in low brightness modes. On battery power, get 3-5 hours of 200-lumen light, 8-10 hours at 100 lumens, or 10-12 hours at 30 lumens. When installed into sockets that are connected to power, the bulb recharges automatically. For extended use, the included USB-C cable can recharge it in 5 hours with an external battery source like a car or portable power station. OM60/5CCTCA/BAT/LEDI bulbs use only 8.8 watts with a maximum brightness of 800 lumens when connected to a power source. Note: remote control distance decreases to around 6 ft. in lamps with shades. Keep homes and commercial spaces lit with safe, reliable LED backup battery lights.
