Amazon BasicsA19 Dusk to Dawn Sensor LED Outdoor Light Bulb, 60W Equivalent, Energy-Efficient 9W, Daylight 5000K, E26 Base, 10,000 Hours, 2 Count (Pack of 1)

They work exactly as intended. I love how easy these are to use. Has a sensor on the lightbulb, so all you have to do is plug it in and that's it. Easy peasy! Has good brightness as well. Turns on and off when they are supposed to. I definitely would recommend these.

I put the bulb in an outdoor covered lamp fixture that is shaded by trees during part of the day. The dusk 'til dawn funcion works great so when it's in the shade during the day it does not turn on, but at dusk it turns and lights up the walkway to my house, and turns off in the morning so I don't have to remember to turn the lamp off and on. It is very bright, but that's what I wanted because my neighborhood does not have street lamps or sidewalks.

Good, bright LED bulbs with a built in photo cell sensors to automatically turn on at sunset and off at sunrise, I have these in totally enclosed, frosted glass fixtures on each side of my garage door and they light my driveway up perfectly, so we'll, my security camera doesn't even need to switch over to night vision. They come on and go off when expected and saved me from running the lights all throughout the day when I'm either asleep or gone.

Much brighter than I expected. Work exactly as intended. Illuminates my entire front yard. When the time comes I will re-order these bulbs.

I used to use a timer in my livingroom, so I got these to put in my lamp. They work very well. Only it is dreary in the winter in my area, so they stay on almost all the time! Quality and brightness is good.

Does the job perfectly for our back door. Easily installs and fits perfectly in a standard socket, does not generate too much heat. Works as it should, goes on at dusk and off at dawn. Easy, peasy!!!

These work great and are very bright! Easier than changing out the whole light fixture!!

These work so good that I have bought four boxes of them. Great price too. The only problem is that they will not not work in older lights. There is an adapter that you can buy for older lights so that you can use the new LED bulbs in them
