These string lights are great for indoor or outdoor. There are one hundred warm lights, LED, and a little over thirty two feet long. They are battery operated but once you put the batteries in you are good to go. They look really awesome, give off a small warm glow and are great year round. They can be used outdoors on the patio, wrapped around a tree or on your gates. They look really awesome in the garden as well. We put them up in the bedroom and it gives off a warm glow. Nice and relaxing.
