K JINGKELAI 4Pack 9W Emergency LED Light Bulbs, Portable Emergency Lamp, Rechargeable Bulb, Household Light Bulbs for Hurricane Power Outage, Home, Camping, with Hook Switch

I bought 4 but already one of the lights quit working under normal daily use in ceiling fan fixture. Pricey for emergency lighting as well, they only last about 3 hours on battery.

Concept is awesome and works. Power goes out and you can still use the lights normally. These lights work like normal light bulbs do, then when the power goes out they keep working like normal light bulbs. They are very dim. I measured the lux with a meter and they all registered between 300 and 400 lux. A normal 60W LED in the rest of the house measured 1300 lux or above. The good news is they all lasted over 10 hours on battery. Guess that's because they are so dim. They will trigger battery mode in multi bulb fixtures, such as a ceiling fan when the switch is turned off. Love the concept hate the brightness. Hence the 3 star. Would be 5 stars if they were as bright as all my other 60W bulbs. Side note, they will not work on battery mode with Wi-Fi wall switches, however, they will work in regular mode with a Wi-Fi wall switch. In the pictures, I included a pic of a regular led 60W bulb and one of these bulbs.

This is very handy... a bright light able to brighten a large area vs the more targeted light of a flashlight. It is barebones, does not take up a lot of real estate. I have one hanging in the coat closet, one just on the shelf in the hall way, and two in our upstairs rooms. That being said, the hooks are very small, around a 3/4in opening, so do not plan on hanging this on your closet rod. It fits nicely on the neck of a sturdy hanger, or you could get a command hook (I have a bunch left over from Christmas) and hang it from that. so two will be used for actual light sources when needed and two will be in their handy spots in case of power outage or to light a larger area than a flashlight can provide. It's a good buy.

I live off grid and use a generator once or twice a week to charge batteries and use appliances. These bulbs work well for the nights I don't run the genny. However,they are not as bright as advertised, and that is the only thing preventing a five star review

I ordered the 4pak of 9W (75W equivalent) they are ABSOLUTE TRASH - DON"T WASTE YOUR MONEY OR TIME. When under normal power the light output is more like 40W. The power failure mode comes on when I turn off the switch to the lights. (The reason I bought them !!)
