Thanks guys. Keep the ideas coming.
Dale,
I was in Home Dumpo the other day buying a ballast for a fluorescent fixture when I saw that stuff. I was intrigued by it due to the extreme light weight. I wondered if the size for T5 tubes might be better. I haven't totally decided against it but all I can find around here are the 4' sections and I am not all that interested in bonding two of them together. Did you run it through the lightning holes and secure it with cushion clamps or did you drill the ribs? If you drilled the ribs how did you protect the tube from vibration?
Mike,
what did you use for the actual conduit? Honest to goodness electrical conduit?
Randle,
I can't make out how you protected the tubbing. It looks like a grommet on the clear and a cushion clamp on the ally. Is that right?
