Debbie, I searched the Lowes website and can't find the lights I purchased but these are very similar.

clear ribbed "glass" but these look like they might be opaque or frosted? I hadn't planned to keep the glass on them but leaving them attached did create a unique look.
Janet, thanks! I might wait before I make the trip to exchange these. We haven't had much sun since I bought them so they might work after all!
