If I could give zero stars, I would.  These are horrible  Such poor quality, they didn't even hold up to 2 months of outdoor use (normal Fall weather in SC).  Half of them stopped coming on at night with no explanation.  We ended up pulling them up and buying similar lights from a different manufacturer that were the same price.  Our new ones are going strong after 6 months with no problems.  Do not buy these; look for another brand.
