Thanks guys. I actually searched for "pvc low voltage led" and got to the Volt site - nice stuff, and pretty good prices too. I just assumed Baz' were LED - now I know why I couldn't find them.
I have been playing with lighting for several months. I have quite a few of the staked-in-the-ground 5 watt LED's (some of which are too hot), and have been putting a few up in the canopies - to varying degrees of success.
What I don't like are the connectors - they are good, but large and bulky.
Here are some first-attempt shots - canopy shots tonight
