I got these lights because I wanted to have my yard light up during the night time. My light bulb outside takes awhile to turn on when you pass the motion sensor. I wanted to find a way to see somehow and make it look pretty at the same time. But, I did not want to turn on each night just to see them. When I found out these lights have a solar power attach to them, I went for it. When I got these lights, they look like big raindrops. They are a warm light color and there are only 30 lights. It says it is 20 feet, but they do not fee like they are since there is about 5 feet of extra cable to reach the lights. So in total looks like about 15 feet. They sure do work though. There are two sets in here. I put one by an outside fence so people can see where to enter to our place and the other by the garden. Turns off during the day and at night, they go on. There is different light settings too, but I only have them as on. Really recommend on small yards and patios.
