We put this around a small blue spruce tree outside and one strand filled it! Tonight we came home and they were on and they are the coolest ever! The lights run through a cool pattern of flashing, etc. haven’t played with any settings, just turned them on but i love them and will be buying more! You cant even see the strand on the tree during the daylight, they hide nicely. I just love them, and the solar aspect means i can put them almost anywhere!
