Question: Approximately how many feet will this light sense outward when up on a wall at 6 to 7 feet high?
Document: These lights are incredible! I couldn't believe how bright they are. The motion sensitivity is great with a wide pattern which activates the light and turns it on. I'm purchasing 6 more!
I needed something for my back door. I have no outdoor lighting and live in the country. I did not want to have to hire an electrician. These work even better than I expected. The motion detection is sensitive enough that they turn on before I even step out onto the porch. The light is not super bright but they work to light the way off the porch which is all I needed.
We placed it outside our cellar and is wonderful. Lights our way without flashlight and when the  power is off.
I purchased a second after the first. One on both sides of the grill. Quick to pick up motion and bright enough to do the job but two is better than one. You will need to buy rechargeable AA batteries though instruction say it comes with 3 it does not and they are nearly as expensive as lamp fixture but I do love them asthetically speaking too.
Answer: no
