Debbie, I think it's easier to just buy the path lights. The solar cell itself is the most expensive part and anything I've ever found was about the same price if not more! You can actually make your own lights but then you need a sensor to turn them on at dusk, etc., etc., etc. I'm going to take the KISS approach and buy the "path lights".
I'm still researching the lights that Lowes has available.
They have a set of four which have 3 LED lights in them =
12X brighter! Of course they're more expensive but the reviews are excellent. Decisions, decisions.....
