Hi Paul,
I couldn't figure out, from the link, who the mfg of these was. Do you have a link? I'm getting ready to start building a deck for my son and wanted to think about some kind of lighting to shows stairs, ect. This said it was waterproof so it might be what i need.

Maybe i can figure out how to make some disco floor lighting.....
