Review: Did not fit I our needs - Not what we had hoped for
Review: Does not work as described - Purchased two. Put one in the kitchen light socket in an appliance that is on quite a bit. Put the other in a one-socket lamp. Left that lamp off a day, then on a day. When I unplug the lamp, the light does not go on. When I screw it into the hanging adapter and turn it on/off, it never goes on. I took down the one from the kitchen light after 4 days and also tried the hanging adapter with it. I have two lights, so two adapters. It won't go on with either. They have been on long enough to be charged. I had hoped that if the light charged and sensed that the lamp was unplugged, it would go on automatically. But at least it should work with the hanging adapter even if that did not work. I don't have the packaging any more so may not try to return...I would not necessarily trust these without taking the ones you buy for a test. They DO glow when screwed into a socket that has power and they are quite bright, but I didn't buy these just to be reg bulbs.

## Features

- POWER OFF, LIGHTS ON - EternaLight LED rechargeable light bulbs are the ultimate essential emergency supplies - works as regular led light bulbs, but will automatically turn on during a power outage.
- DUAL-POWER VERSATILITY & PORTABLE DESIGN – Stay prepared with an emergency bulb that charges in just 4 hours via standard light fixtures or in 8 hours under a clear, direct line of sight to the sun using high-efficiency solar panels. For off-grid use, simply remove the bulb from any fixture and screw on the included E26 Socket Cap to transform it into a handheld flashlight or a stable upright tabletop light using the integrated On/Off button. Whether you are navigating a power outage or using it as a portable lantern for camping, this 500-lumen bulb provides up to 6 hours of reliable, battery-powered illumination.
- VERSATILE 3-WAY OPERATION & CLEAR USAGE – This emergency bulb is designed for three distinct modes: as a standard light bulb that charges while in your fixture, as a handheld flashlight by screwing on the included E26 Socket Cap and using the manual On/Off button, or as a hanging lantern using the integrated accessory hook for tents or branches. For situations where the cap is unavailable, you can even power the bulb by simply wrapping your hand around the metal threads and touching the end cap with your finger to complete the circuit. Whether for home backups or outdoor camping, these clear operational methods ensure you have reliable, portable light in any environment.
- STANDARD A21 FIT & EXTENDED RUNTIME – Engineered to provide reliable safety, these rechargeable bulbs offer up to 6+ hours of ultra-bright 500-lumen LED illumination on a single charge. Designed with a Standard A21 bulb shape and a universal E26 screw base, they are built to fit most common household lamps and fixtures; however, we recommend checking your fixture clearance against the A21 dimensions to ensure a perfect fit. Simply screw the bulb into your base to enjoy effortless, high-performance light that keeps your home and family protected during any power outage.
- ENERGY EFFICIENT LIGHT BULB - EternaLight doesn’t just provide peace of mind, but saves up to 80% on electricity costs.

### ⭐⭐⭐⭐⭐ Let there be light!
*by J***) on August 24, 2024*

We recently had a 15hr blackout. These bulbs are great. They give out a lot light with out making the spot hot. If you keep one in a desk or floor lamp and sometimes turn it on, even if there’s no power to the lamp, the bulb will light if you have put it in the sun or on occasion turned on the lamp! You can also charge the bulbs by putting them in the window to collect sunlight, and hang them around the house, hanging one in the bathrooms. You can also walk with them like a flashlight! Great Christmas gift for loved ones. Get and give the 4pk! -you will be glad you did :)
