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

The color temperature on these bulbs make them very versatile. The bulb itself is quite big but it works in my open lampshades

Recently, we have experienced more power outages than normal due to a lot of construction around us. We have some flashlights and a few LED rechargeable lights, but I wanted something that would work in existing lamps, so I gave these a try. They work great. I've used them for 3 power outages that lasted 5 hours or longer and these stayed on the entire time. The only drawback is that they are a little taller than a regular lightbulb so they may not fit in every lamp depending on how the shade is attached and how much room there is, but in the two lamps we used them in, they fit fine. They are easy to use and lasted a long time.

They are a good buy. They also work for so many hours after the electricity goes out. Hopefully I don’t have to test them out this weekend.

I live abroad and we have unpredictable and sometimes, even scheduled power cuts. I have these bulbs in our lamps so if it goes out at night, we don’t go into complete darkness. I have small kids so this helps a ton. They are automatic and simply recharge when the power comes on. I just plug these in and ignore them. My first set endured at least two years so they last a long time. Two notes: 1. They are bigger and take up more space in the lamp. Be mindful of that. Might not fit some small table lamps. 2. They dim a good amount when they operate on battery. They illuminate a space but not at that maximum brightness when powered by electricity. They work well and have a long run life so overall I am really pleased.

These are such an easy switch to make if you have frequent blackouts. Our power goes out at least once a year for over a day or two, and while I'm not sure how long these will last, they've helped us in some of the shorter outages in the last year. Not as bright when running on reserves, but keeps the room lit and one less thing to worry about.

Bright and helps when power goes out

This is a great product. It works well when my electricity goes out. I no longer have to rely on candles.

I usually love GE's bulbs and their led balanced spectr grow bulbs for houseplants are really great but these rechargeable ones are really just okay. I was hoping to use one in a lamp I don't have an immediate outlet for and I don't like having an extension cord where people can see it in order to plug it in.. and the bulbs work like a regular led when placed into a lamp that's plugged into the wall and turned on... And that's when they supposably charge up... They're a nice warm and bright tone when they're in a plugged in lamp. Just right. However. When they are on flashlight mode or in a lamp that has no power connected they are pretty dim... Really a nightlight at best. I guess I should have expected as such but they won't really work for what I wanted to use them for. They would be good to have for power outages I suppose... Although it seems like the battery life within the bulb doesn't seem that great. The bulb died within a day after charging up for a few days. Not sure if these are worth buying if they cost more than a regular led. But if you need a lightbulb that charges up and lights up without being plugged into power source, go for it. Could make for a cool photography prop. I feel like the idea of these is good and so maybe with some design / engineering improvements they could be more impressive than what they currently are.

We bought these bulbs for when we experience a power outage and they do not disappoint. We simply installed the bulb in our main lamp in the living room and it automatically charges it up. The light is bright and provides a great deal of light. So when we had a power outage the light stayed on since it was fully charged and lasted for at least 7 hours before we headed to bed. An amazing product and a life saving when you need it!

Tiene opción de foco y linterna, está muy bien diseñado, dura un tiempo muy bueno, la luz es buena y alumbra muy bien .

We have a camp off grid and we love these bulbs. They charge while the generator is on and then when it’s not we just turn the lights on and off like normal. I highly recommend!

I wanted a light that was rechargeable independant of the lamp but these only recharge in an electric lamp. I thought I'd keep them anyway and use them in my lamps, but they are too bid for my lamp shades.

Funcionales. Me gusta que traigan un botón para cambiar de la función de bombilla común a lámpara, mejor que otras opciones de focos recargables que tengo, aunque son mucho más caros. Lo único es que la luz es cálida, ojalá y hubiera opción de luz fría. La luz no es muy intensa.
