The task for solar lights is to charge their batteries enough every day to power the lights all night.But short, frequently cloudy winter days mean less charging time, and cold weather means batteries that don’t want to give up their full charge. So buying these lights in late November gave them a great test. They passed!I purchased eight lights. Six get at least 5 or 6 hours of winter low angle sun, while two get less due to overhanging shrubbery that blocks sun rays for a few hours. The ones that got the most sunlight work all night from dusk to dawn, while the other two stop working about 5:30am, which is good enough for me.I didn’t use screws or the provided Velcro to mount them permanently, knowing my snow removal crew would hit them with their shovels. I try to remove them if snow is forecast, but forgot one evening and all eight got a rude shovel treatment, then were buried in a snowbank until I found them days later as it melted. None suffered any damage!The color temperature is a pleasing warm color and the lit up steps add a pleasing ambiance to the front walkway. I highly recommend them.
