I have been playing around with the $1 solar sidewalk lights from the Dollar store again. If you remove all the stuff, metal top cover and stakes, you end up with only the collector, light defuser and LED. I cut off the extension that the stakes slide on. I built a lamp housing with a hole the same size in the top. A little Goop seals it and keeps it in place. This is a prototype, pending the approval of the CEO........wife.
I have other ideas in the mix and will show that soon
