Rirool Solar Christmas Lights Outdoor Waterproof - 100 LED 39ft Blue String Lights with 8 Modes for Garden Party Tree Halloween Decorations

these lights are easy to install, and work really well. I wrapped them around my deck rails and put the solar sensors on top of 2 deck posts. the lights do not need direct sunlight to recharge during the day, and yet they stay lit for approx 6 hours at night. the sensors have been covered with 2 inches of snow for the past 5 days, and the lights still light up for a couple of hours. I should also mention that these past 5 days have been mostly cloudy, too. please note, these lights come on when it's dark, and turn off when their charge is gone (in my location they are on from 5-11 pm at max)

Better than the larger strings. The larger strings have too many lights for the size of the solar collector and battery. These stay on much longer during these short winter days and long nights. Also, the shorter string is less prone to tangling.
