Neporal 4 Pack Emergency-Rechargeable-Light-Bulb, Stay Lights Up When Power Failure, 1200mAh 15W 80W Equivalent LED Light Bulbs for Home, Camping, Tent (E27, with Hook) (Daylight)

Lights work great, easy to charge, hook for hanging up, and off and on switch for control! Great for emergencies or lighting up dark spots!

We often experience power outages when Nor'easters blow in, so I bought a pack of these rechargeable bulbs to help. At first, I thought they were great. They worked as advertised. You keep them charged, and when the power goes out, the bulbs stay on, so you're not left in the dark looking for a flashlight. They stayed lit for at least five or six hours, giving you the feeling that you still have power. I've used them for probably four months now, through two hours-long power outages. But today, while in the kitchen, I heard the bulb I have screwed into the ceiling light socket, where it has been for four months, begin to sputter and pop. It sounded like a Tesla coil. I immediately took it out. It was not hot, nor was it discolored. I read that these bulbs have a tendency to buzz sometimes, but this was not just a buzz. So, because of this experience, and because I cannot find anything more online about it, I am sadly not going to use them anymore. I was using this particular bulb in a socket controlled by a dimmer switch. I did read where that can have an impact on the behavior of some bulbs. So this may not be a bulb problem, but I will not take a chance. Too bad, because I like them. So, I would suggest just keeping an ear out when using them just to be sure.

We bought these a few months ago. Have been using them ever since as regular bulbs in our lamps so they would be charged should the power go out. A couple weeks ago, we had a monsoon come through that knocked our power out for a couple days. Not happy about the power being out but looking forward to trying out these bulbs. Instructions say you should be able tap the top of the bulb to turn on but that did not work for us on any of the bulbs. The only way we could get them to come on was to screw the clip piece on. Then they lit up. We were under the impression they could remain in the lamps and double tap them to come on. Nope. We just hing them by their clips in places we wanted light. They are very bright and do last 3-5 hours. About hour 3, they begin to lose charge and after that, get less and less bright. But what is nice, if you just need them for an hour or two, you can remove the clip piece and save some juice for later. I do recommend these for short power outages. Ours was out for 2 nights so the second night we did not have any charged bulbs.

The light bulbs do exactly what they are supposed to do! If you lose your power, the light will stay on. Also, by attaching the item with the push button, you can use the light bulb and hang it anywhere to use as a lamp even without power. I live in the country and we lose our power quite often. These light bulbs have saved me from living in the dark (even without a generator) many times!

Great emergency light bulb! Three setting for low, medium and high. And they hold a good charge and last quite a while!

These are great. Just put them in regular light and they charge up each time, then if electric goes out, they are there and READY! Gave for xmas and everyone loved the idea!

Does not com on when the power goes out as they skillfully claim

Holy Cow, I can't believe how great these are! They do last, they are bright. The 3 settings are quite adequate. I can see 'low' would be enough , in a blackout to handle any in-house or close up task. Any light in a DARK room/area is a good thing. These have pretty good longevity also,(Good Battery) H/M/L settings are handy. I drove home in the dark on my golf cart with one and it was a life saver when my lights quit working. Every person I've gifted these to has been amazed and loves them. I leave mine i the cellar light so it gets a good charge at least daily. Just find a commonly used light and swap these in. Great camp/prep/tent/Kayak tool. Functions fine so far.
