As of now (9/2018), are solar-powered landscaping lights a sensible option?
In 5-year intervals, for the past 15 years, I've been suckered into buying solar-powered landscaping lights and every time it has been a complete waste of money. The lights are dim, last for about two hours after dark, and the battery loses its ability to charge in about 4-6 months.
Before I repeat the same mistake, I figured I'd ask: Have solar-powered lights improved significantly over the past 5 years to the point that one should consider buying them again? Perhaps this question could be answered for path-lighting lights as well as lights designed to be pointed at trees and house walls.
