What Are Electric Bulbs with Built-in Batteries?
Electric bulbs with built-in batteries are innovative lighting devices that function like regular LED bulbs but come with an internal rechargeable battery. These bulbs continue to operate even when the main power supply is interrupted, making them ideal for emergency lighting.
How Do They Work?
These smart bulbs charge automatically while the power is on. In the event of a blackout, the bulb switches to battery mode instantly. Most models include a sensor or switch that enables seamless transition between AC power and battery operation.

- Easy Installation: Fits into standard bulb sockets with no extra wiring required.
- Portable: Can be used as a handheld emergency light when removed from the socket.
Where to Use Them
These bulbs are perfect for:
- Homes in areas with frequent power cuts
- Emergency lighting in offices and hospitals
- Outdoor lighting during camping or night events
Buying Tips
When choosing a bulb with a built-in battery, consider:
- Battery backup time
