I really love these lights. I am addicted to any kind of lighting. I tested these lights at home but I am going to be using them at camp. They are not very bright so if you need bright lights these are not for you..if mood lighting is what you are after these are perfect. They come in a set of five and are strung together ..one solar panel is attached to power the lights. On the back the yellow button turns them on and off and the black button is a dummy. They are very simple to put together..you only need to attach the stake..making sure to place the wire in the grooves to protect the cord. . The lights are made of weather resistant materials. Acrylic is used for the lights with stationary bubbles. The lights slowly fade to a few different colors. (red, orange, green, yellow, blue, teal, pink and white). The stem is made of stainless steel to prevent rusting. The stake is s heavy plastic. When put together it is 14 inches tall and spaced 31 inches apart for a total of 12 1/2 feet. You are able to place them close together or as far apart as they go but they are all strung together and can not be used separately. KINGSOLAR™ I received this product free.
