More than rugged enough built for its purpose. Not so bright that if you look at it you see stars afterwards. My mom loves it out on her deck. Can't get her back inside. (Tech tip: These are 3/8" of an inch in diameter. Make sure that is the size of the electrical cable clips you buy. They are ideal. 1/2" will fit loose. I didn't get clips with mine. That's okay. The clips I've seen others come with are usually deficient compared to the $2 package at the hardware store.)
