I like the effect of solar lights along my walkway and around my garden, but hate spending money on things that don't last and I've never had any long term luck with these things. The batteries are expensive to replace and my experience is that after shelling out money for replacement batteries, the lifetime is even less than what they provided originally. Ironically, I think UV rays are clouding the little solar cell, much the way headlight covers on cars cloud over after a (much longer) time. Either that, or the solar cells themselves end up being of such a poor quality that they just don't last. My wife and I were in Bed, Bath, and Beyond last night and they had some really cool looking solar garden lights that caught my attention, but I just couldn't bring myself to spend the money for what I thought might only last for one season before I'd have to pitch them. Anybody know what the deal is with these things, or have any advice for getting them to last maybe a few years, at least?
