I love these lights so much I want another set! They are on back order right now but the minute I get an alert I am purchasing them. Two sets will completely light up your back yard, they attach to each other so no need to really worry about needing an extra outlet. They have a beautiful glow, each bulb is about 11 Watts, they are 15 bulbs per string and 3 extra bulbs were also provided. Easy to hang up and are heavy duty!
