  • Re-review of these emergency power outage light bulbs
Size: 2 Pack
This is a re-review. Amazon shouldn't request a review of a product such as this product until the customer has had a chance to use it. We had an extended outage this past week and I was able to see these emergency rechargeable light bulbs in action. Apparently the bulb is able to decifer the difference between a power outage and a flipping out of the light switch. The bulbs that were installed on the light fixtures for the stairway leading to the basement, stayed on for 4-5 hours before they started to dim. I highly recommend these. ... show more

  • They do work....but you must do the following
Size: 4 Count (Pack of 1)
The bulbs first have to be charged up if they are not going to be used until an outage. They only work in stand alone lamps with one bulb and it must plug into the wall and switched on at the lamp. I keep a small lamp in my aviary and turn it on every night. We had an outage one night and the light bulb immediately switched to emergency use. I did not have to worry about my birds being in total darkness (they would have gone crazy). I then turned on my single lamp in the living room. The bulb was already in place and charged periodically in normal conditions. It gave us enough light to move about the room. They do not work with ceiling fans or cam lights. ... show more

I have had these products for about two years now and they are still goin strong. I live in the Caribbean so we get hurricanes and loose power or just on a regular day you loose power as well.

  • Great idea! But may or may not actually work for you...
Size: 4 Count (Pack of 1)
TL;DR: These may or may not actually work for you, but they're a nifty toy for electronics nerds :) These lamps really do work, and they are quite clever, but I'm giving them 4* only because it could be difficult to predict if they would work in your specific configuration. If you're considering these, it might be best to start with a small set, so you could test them in situ before you get a bunch more. This device is able to tell the difference between the power being out because the switch is off (or it's not plugged in) and the power being out because there's a blackout condition (and the switch is on). When the switch is off, the device would detect an open circuit. When the switch is on but there's no power, the device would detect a closed circuit *through other appliances plugged into the same circuit*. This means you couldn't test it by simply pulling the plug, because this would be equivalent to switching it off. The very best way to test it would be to install it where you intend to use it, and actually cut the power at the circuit breaker. A less intrusively way to simulate a blackout might be to plug this and something else into the same power strip, and turn off the power strip. It is mandatory to have something else plugged in together with this lamp, but many types of modern devices do not work to help this lamp detect blackout. The main requirement for the "helper" device is that it must close the circuit. So a resistive load, such as a simple incandescent lamp, would work. An inductive load, such as a fan or an air purifier, would work. But anything that's decoupled from the circuit through a capacitor, such as a USB charger or a computer PSU, would *not* work. Heck, even another LED bulb (which has a switched-mode power supply built in) would not work. And the "helper" device has to be turned on during the blackout, or else it might as well be off the circuit. There's also a false-positive condition. When this is deployed with a group of light bulbs (or other devices) to be turned on/off by the same switch, such as in a chandelier or a candelabra, then it would think there's a blackout if you just turned off the switch. In my photo, I have it deployed with a strip of incandescent bulbs, and this emergency light always turns on when I try to turn the lights out. But I guess it would work if *all* the lamps in the strip were LEDs, because it would ignore the other LEDs. That's a lot of words to say that the concept is really clever, and I loved playing with it, but it's not easy to predict if it'd work in an actual circuit without testing it. ... show more

  • They work great
Size: 4 Count (Pack of 1)
They are one of the less expensive of backup light bulbs. they work well and you can lower the light levels to keep them running longer, or keep them at 100% normal brightness. Which is something most of their their peers do not have. They work just as advertised. If your power goes out you can still turn them off and on with you light switch. They will also stay on in a power outage if you had them on at the time, vary handy if you are in the shower. Being able to turn on the lights in your bathroom in a power outage is just a great feeling. From the testing my friend and I have done you can use them in multi light fixtures too, as long you change all the light bulbs to backup light bulbs. I have read that some houses wiring may not be compatible with these kinds of light bulbs. So you start with just one for testing. ... show more

  • Rechargeable Emergency Light Bulbs
Size: 10 Count (Pack of 1)
Love these!!!! My mom was in rehab and couldn't see to reach the light switch at night - Hung one on her bed and she could safely see to get up during the night. During tornado weather, we lost power and hung these in bathroom, bedroom, etc so we could navigate at night during the power outage.

  • Easy to Use! Multi-purpose, emergency or planned power outage supply!
Size: 4 Count (Pack of 1)
I love these bulbs! Great for when power goes out, or need a flashlight but can't find one. Just charge the bulbs by screwing them into your regular lamp, and turn the lamp switch on. Best if used with a non- dimming, single switch (on/off) standard lamp. It may take a few hours to charge when you first receive them because they have been in storage, (just like when you get a new cell phone). After they are fully charged you can keep them in the lamp, or screw them into any other standard light socket. If you want to take it outdoors or simply need it as a flashlight, turn off the lamp was charging in, then unscrew the the bulb. Take the white plastic hanging screw socket thingy that came with the bulb in the box, and screw the bulb into it. Under the hanging mechanism/hook, is a black button, press that button and the bulb should work. (Sometimes it helps to dampen your finger and touch the metal base of the bulb to help with power conduction). ... show more
