Outdoor Solar Lighting Review for the Home

There are two outdoor solar lighting systems that I would like to do a review on.  There are many out there but these two are consistently top rated on Amazon.

The first is a set of 12 copper outdoor lights by Homebrite, item number 30867.  They provide a warmer light and look very unique.

The second is the Westinghouse Solar Outdoor Lights, item number B0017QG172.  They are a silver color.
