## Customer Reviews

### ⭐⭐⭐⭐⭐ Works Good
*by J***T on August 7, 2024*

Does what it claims to do. Easy to install.

### ⭐⭐⭐⭐⭐ Rugged and Great Quality!
*by G***A on November 18, 2018*

I bought this to use with the front entrance of our subdivision to control the LED large floods that light up the front at night. This is a very well-built photo cell and withstands the weather and works perfectly. Much better than the home building stores offer. I have it wired directly into the power breaker box and it gets the job done!

### ⭐⭐⭐⭐ Says do not mount with wires up
*by R***R on October 21, 2021*

Our HOA recently replaced our old neighborhood lighting system with LEDs. Problem was they were staying on until 10 AM. We had an electrician look at the system and he put in 2 new K4221C switches and that seemed to help but a year later the lights were staying on until 10 AM again. Was going to replace them myself but while reading the reviews I found one that said the manufacturer said to use the EK4236S for LED lights. Ordered one for a test and realized that system only drew about 100 watts so was able to combine the two circuits into one. It's working well and the light go off promptly at dawn. Only problem I had was the instructions say not to mount with the wires up but that was how the old switches were mounted (at the bottom of the switch box). Decided they were worried about collecting water so filled the wire side with silicone and let it dry before I installed it. No problems so far. Took off one star for not warning about the orientation problem. in the product description.
