“I strung nine of these down the perimeter of a client's property to mitigate issues in an alley. Their fence was not pretty to start with, but at night, it is now. All for the consumption of about one 100W light bulb. The housing is solid. Only ding is that the screw to frame attachment may be on the mid to low end strength wise. Adhesive caulk around the perimeter may mitigate that concern and time will tell.”
