These are the perfect outdoor string lights. The price is right and light set is well made and appears heavy duty. The lights bulbs are a great size and provide the perfect outdoor patio lighting. The light strings can be added together for as much lighting as you need. We have put them along our fence and on our trellises. We live in Fl and our weather can be very hot and often very wet and our lights have never failed in the past 3 months. We bought 4 sets, put them on a timer and just love them.
