PERFECT EVENING AMBIENCE!Solar lighting is just the right amount of gentle light under the pergola.  The quality of light is slightly on the blue side. If you are looking for a warmer incandescent quality of light...this is not it.  The light feels like the early morning light before the sun comes up.  The little industrial cages are a mottled silver and about the size of an egg.  They do last all night just as promised.  We LOVE them!
