Hey Ray, we really enjoy our blue LED moonlights. They make kind of a spotlight effect slicing through the water that is really very pretty. We just used some cheap clip-on sockets from Home Depot (same kind as many of us use to light the fuge, full-size lightbulb socket attached to a clip) and then bought some inexpensive blue LED bulbs that screw into a full size socket. I'll see if I can come up with the link for where we found the good deal on the bulbs or maybe Mike will post it.
