I'm with Gwen. Start slow and adjust plants up till the leaves turn yellowish. No need for red. As for bulbs try this site
Linear Fluorescent Tubes This Company is very trustworthy and has good products at decent prices.

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Masdies, Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)
