After a half hour, I gave up.

The sensor is not very sensitive to light.

I have owned several of these photocells from Intermatic so I do have experience with them. In the old days I needed to use the light blocking shield on them to reduce the amount of ambient light so they would come on a dusk. Not sure what Intermatic has done but these new ones I purchased stay about 75% of the day, they have no sensitivity. Yes, I have tried pointing them in different directions etc.. and I have more than one installed. They will work fine if pointed at the sun but if you are mounting on an outside wall that has any kind of shade they are worthless. Perhaps they are making these overseas and the quality of the cell is just junk.

More disappointing news, I called customer service at Intermatic and they had nothing of relevance to say, nor could they suggest any of their other models that had some sensitivity. Perhaps I got a bad batch, but i am not going to waste my time or money with these again.

Bought this sensor to control a night time security light with a CFL bulb. It works good, no flickering or problems normally encountered with CFL's and sensors. The sensor is not very sensitive to light. It comes on early and shuts off late. Should be mounted where the daylight can get to it easily.

I attached this to a 20W LED outdoor spot light I built for my son who lives in another state. He is not familiar on how to wire, so I also attached an extension cord to the NEMA box so he could just hang it in his backyard and plug it in. I wired this per the instructions but the light never turned off. It says to wait for up to 15 minutes for it to turn off and it was in a brightly lit area. After a half hour, I gave up.

It installed easily and works as it should. I'll raise it to five stars if it lasts a few years.

Good product. Reasonable price from Amazon !! Bought this dusk to dawn photo cell to replace an existing unit. These things can be a little hard to work with at times....

After replacing several big box store sensors which did not meet my expectations decided to try this one purchased through Amazon.
Packaged well, wire diagram easy and straightforward and has worked well since installed. Will update review if it fails prematurely.
