GE LED+ Backup Battery LED Light Bulbs, A21 Rechargeable Light Bulbs for Power Outages and Emergencies, Flashlight, 3 Color Temperatures (2 Pack)

Truly great innovative product. Such an easy backup plan for power outages. Could also be used to provide light during peak-rate periods of the day, while charging during low-rate periods. Can even be used as a handheld flashlight. Great that the kelvins are also adjustable. Would be a nice bulb even without the battery backup but with that backup, it is a great bulb. Fits, looks and acts like a normal bulb. Great value for the features. I use them in all of my lamps. During a power outage, of course I won't have all the lamps on at one time so that means overall an even longer period of backup lighting will be available. Using these means I can use my other backup battery power sources for things other than lighting. Too bad more people don't seem to know about them.

Best investment ever... specially during hurricane season. If you live where electric surges are common and/or hurricane season usually takes power out, these are essential. They are just like a regular light bulb, they charge as long as they are installed. Then, when the power goes out, they stay on. If you turn the switch off, they turn off,... if you turn it on, they turn on. Just like a regular light bulb, just that keeps charge inside when a power surge happens. They last hours. I've had mines on for 8 hours and never lost intensity. May work for longer, just haven't tried it yet. I decided to put one on the hallway, another on the kitchen and one on the living room. That way, main areas keep illuminated when needed. Doesn't have a remote control, but dont really need it either.

These bulbs are perfect for power outages! I have recommended them to friends and family who have all bought them. Easy to use, just like a regular bulb. They have long-lasting light when power is out. They are compatible with any standard light. They are well worth the money.

These are so great to have as back-up lighting in a power outage. I highly recommend having a few of these throughout your home. I like that I can adjust the color with a switch! The LED makes them energy efficient which is great.

These are great for permanent switched light fixtures. I do wish they were the smaller A19 size instead of A21, but they still work for my needs. I use these in a bathroom ceiling fixture that is the first in the house to be affected by power issues from the main and the brownouts from road work has ruined several quality led bulbs previously. The built in battery on these seems to have protected them. They are great for power outages as the room they're in has no windows. I only have 2 minor complaints. I am not a fan of the looks and light output only coming from the top, which is more noticeable in the larger A21 size. Also, the lights stay on for a moment after the switch is turned off, seemingly sensing if it was the switch or power. When power was out, or the breaker switched off, they do still turn on with the switch, so whatever it uses to sense is working well.

These are great for when the power goes out.

There’s lightbulbs are awesome when traveling or away from home I don’t have to worry about the light not being turned on porch light that is!

Not sure because no outages yet.
