OMG…. these are amazing… amazing… amazing. They light up my yard quite nicely, and I like the effect that they’re like fireflies. I’d love for the manufacturer to come out with these in a yellow-ish / green-ish color so that I could keep them in my yard during the summer and give the illusion of having fireflies. I think the spacing on these could be tighter – about every 4 feet…. I paired these with the red, green, blue laser lights for the holidays… amazing….
