4-Pack, Dusk to Dawn/Day Night Sensor, Photoelectric Switch, Photo Cell Sensor, 110V/120V/220V/240V Input, UL Listed, IP65 Water-Resistant Photocell for Outdoor Light

Worked perfectly to control a low voltage transformer for outdoor lights. I’m a professional lighting designer and technician. Seems like a high quality product that should handle the elements well. No need to spend more money on anything else. Rubber grommet seals nicely on my enclosure. Looks very clean and high end too!

Easy to install and my existing light fixture and works as expected.

I read a lot of reviews where people bought dust to dawn lights for their flags. In most cases, they were having trouble with either the dust of no sensor leaking, or the light leaking. I realized that since I was going to be running a circuit out to my flag anyway, why not go ahead and get a separate sensor, but if I did that to get a very good one. This one fits the bill very nicely. I mounted it on the side of the box, and it makes a very nice waterproof seal. I actually turn it down just a little bit to allow the water to drip off of it as well as to reduce the sensitivity. It works perfectly well.

Works fine, but I don;t think any of these sensors last more than about 8 years.

These dusk-to-dawn photoelectric sensors are exactly what I needed for my outdoor lights and a sign. They automatically turn lights on at night and off during the day without any fuss. Installation was simple, and the sensors work reliably every time. The IP65 water-resistant rating means they handle rain and weather just fine. Great value for a 2-pack that’s UL listed and supports multiple voltages!

Work well.

This sensor is doing exactly what I expected it to do. And I was able to mount it away from the light it was controlling so that it would not fail (go on and off, on and off) when the light would come on. I had another do that on a different unit. And the price was right.

Easy to install and fast shipping!
