Review on SOLARBABY Solar Fairy Lights: Waterproof Outdoor Christmas Decorations with 8 Lighting Modes - 200 White LED Solar String Lights for Home, Lawn, Garden, Wedding, Patio, Party, and Holiday by Angela Mason

I bought one of these (white) and it was excellent so I ordered a second one. The second (its solar panel) is literally in the same place. The first lasts all night (from 4:30 p.m. to 6:15 a.m.), the second does not. I'm disappointed and wondering if I can return or exchange a second one. I liked these lights so much I bought the blue one and a bunch of colored lights - same thing - they work all night. Update - a strange white film covers the solar panel - no charge is made. This hasn't happened with the other five lights I own.
