Here's a try at showing how I made my light setup. First image shows one of the 2 lights in front of windows showing how I attached the socket. Bulb just hangs bare.
Next one shows the single lamp which I mannually plug in later in morning to supplement others.
This is nothing fancy, but it works. I measure 1200 foot candles away from glass and 2500-3000 near windows. I plan to use either this type setup with two bulbs over my new terrarium or a 48" bank of T5 bulbs.

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.)
