Dusk to Dawn Light Bulbs, 9W (100 Watt Equivalent) Automatic On/Off Light Sensor Bulb, Built-in Photocell Detector No Timer Required E26 A19 120V 6000K Cool White for Indoor Outdoor Yard Patio Garage

After two days of use, very happy with these bulbs so far! They work exactly as described for my outdoor lights, turning on at dusk and off in the morning. No more accidentally leaving the lights on all day or making delivery drivers come up to the house in the dark! If you flip the switch for these bulbs during the day, they will come on for a few seconds to show you that they are working and then turn off/return to the light-sensing mode, which I found very helpful!

Works Great! Light is ultra white not yellow which is good at night. Comes on at dusk and off at dawn as it should. Would buy again!

Love these dusk to dawn lights. The sensor is built right into the base of the bulb making it so easy to install in outdoor light fixtures. Prior to getting these, I had used outdoor bulbs that had a separate timer piece that attached to the actual light bulb. Got to be too difficult to install the old ones in the outside light fixtures so turned to these and am much happier.

It’s very bright and it works

I really want to give this a 5 star review! I think it's fantastic as far as doing what it says buttttttt I'm concerned about the 4 pack dying out, as per reviews online, people claim these eventually give out and that leads me to my issue with them. They are so dang good at turning on, that they turn on before it's dark outside. Don't get me wrong .. I'm thankful to come home to a house that's lit up but when they are on for so many hours before it gets dark, how efficient are they?! Love that the sensors work but hate that they are TOO sensitive ... lol If that makes sense! Grateful for the technology but it needs to be tweaked just a bit basically. As soon as the sensors don't process sunlight outside, they turn on so even in that pre-dusk faze, they turn on and stay on until the next day when the sun is back out (even after dawn). I notice they turn off when they have DIRECT SUNLIGHT on them so if you live in an area with more shade, they will constantly stay on, even in broad daylight. Priced well for what they do. They are solid, as any typical bulb and they provide two different colors. The bright white light has a blue hue whereas the regular light, has more of a yellowish common soft glow. We went with the white and it's extremely bright! Super happy about the visibility when they are on. Would buy again because of the convenience that we don't fumble for keys to open the door or turn on my cell flashlight first anymore. Best part too is that we didn't have to pay an electrician to change anything. You simply take out your current lightbulb and screw this one in and voila! Job is done and you have lights that turn on automatically. Also, I should mention, you have to leave the light-switch to the ON position 24/7, for this to work.

This is the best light sensor bulb I have ever used! The sensor is cleverly integrated directly into the bulb (I believe the tip acts as the sensor), so it's completely invisible from the outside. Even recessed deep within my porch ceiling, it works perfectly—shutting off reliably even on cloudy days. Unlike other bulbs that stay on for nearly 20 hours a day, this one truly knows when to power down automatically.

Great bulbs. It's so nice to not have to worry if your out later and didn't turn your outside light on. This light comes on and and goes off in the morning! Will definitely be purchasing more
