I wanted to replace my existing light on the back of my house that stands about 20 feet. This thing is a beast, and the amount of light that it sets off is crazy! It lights up my backyard like a baseball diamond... Which is exactly what I was hoping for! Relatively easy installation very sturdy very well-made.
At first, I didn't think it was working. I had the cover over the light sensor and it still wasn't coming on...but once I put my hand over it...the light came on, so I think the sensor is either really sensitive or there's some seepage around the cover, but you can either turn the sensor off, or it will come on once it actually gets dark.
This thing was perfect for our backyard party. And because it's up high enough it's not blinding anyone in the eyes. I love this thing.
(Updated on November 10th):The customer service representative told me that the cover needs to be opened. Only after opening it will the light sensor function properly.
