This year, I tried a set of solar lights made by Malibu. I've had them for
about 6 weeks with no problems. They seem to take a charge well - they light
up every evening - even the ones in partial sun.

Be forewarned that they don't throw a lot of light - maybe they could
illuminate a path - maybe not. I'm using mine to accent a few plants and add a
little interest to the garden.
