Rechargeable Light Bulbs for Power Outage - 2000mAh Emergency Battery Light Bulb, 500 Lumens, 5W, 5000K Daylight, E26/E27, 120V, 2-Pack

The rechargeable emergency light bulb from YKDtronics can be used as a traditional LED bulb for daily use, automatically charging when in use. In the event of a power outage, such as during a hurricane or storm, the built-in 2000mAh battery backup can provide 3-4 hours of lighting, so you don't have to worry about being left in the dark.

To charge the emergency bulb, it is recommended to plug it into a power socket for the first time. This is to avoid the bulb's battery being dead, which would prevent it from being turned on by the hook switch cap, fingers, wet cloth, or power cap.

If the bulb is not working on the E26 base during a power outage, check to ensure the switch button is turned on. The bulb does not have an automatic opening function, so you need to manually turn on the switch button before the bulb will light up.

To test the emergency mode without a power outage, there are two methods:

1. Screw the rechargeable bulb into any E26 fixture, plug it into a 120-volt outlet, turn on the bulb, then cut the main circuit breaker. The bulb will remain on; turn it off, and it will be turned off.

2. Screw the emergency bulb into any E26 fixture, unplug it, connect the prongs of the plug with a wet cloth, and the bulb will turn on. Screw the bulb into a hook cap, turn on the top switch, and the bulb will light up. Use your fingers to touch the bottom and bottom side at the same time, and the bulb will light up. Use a wet cloth to touch the bottom of the bulb, and it will light up. Screw the bulb into an E26/E27 base, then insert the plug into a wall outlet and turn on the switch, and the bulb will light up.

These rechargeable light bulbs are not just ordinary bulbs. They can be used as traditional LED bulbs for daily use, automatically charging when in use, and provide a necessary emergency light source during blackouts, storms, and hurricanes. They are easy to install and disassemble, and can be used as a flashlight in the face of emergencies, reducing the tension caused by darkness.

The battery backup light bulbs are portable and have multiple ways to emit light, including through the button on the cap with a hook, or by installing a handheld grip to use them as a flashlight during outdoor activities. The E26/E27 LED bulbs are energy-saving, with a 5W LED equivalent to a 40W normal bulb, providing 5000K daylight and 500lm at a low energy cost, saving at least 85% on electricity bills.

YKDtronics offers a 12-month warranty, a 30-day unconditional refund, one-year warranty service, and lifetime technical support, with 24-hour friendly customer service. If you have any issues with the bulb, you can contact them via Amazon at any time.
