Got these a few days ago, installed some of the included mounting brackets, and have been using it without issue since then. Obviously, brightness and color are adjustable, but at full brightness, these things almost light up about half of the yard. I attached them to the deck stairs in hopes of lighting the steps at night, and was not disappointed. Included are daytime photos of the strip and the brackets, and nighttime photos of the strip, the steps, the yard with them both on and off, and a few different colors.
Also, yes, like a few of the other reviewers, the last couple inches of the strip did not light up. At night, it really didn't seem to matter.
