We started out with the cheaper plastic solor lights they did suprisingly well lasted 3 or 4 years outside year round. We now have the much better brighter lights made of metal and glass they should last longer. I wanted mine on taller stakes because I wanted them visible over my garden plants so we used pvc pipes that the lights would fit into. Painted the pipes with paint for plastic to match the lights sawed to the size we wanted works very well.
