Here are a few pictures of the light stands I built this year.
I used 1 1/4" pvc for the stands. The reflectors are from clamp-on lights you get at hardware store or Wal-mart. I removed the clamp-on part and bolted it to a 3" inside corner bracket. I painted everything white ( to keep wife happy, rather happier). They are all on timers and I used 6500K CFL's.
Mounting the outlet on the base allows me to plug in a humidifier. Saves on cords and outlet space
I am new to all this, so this is my first year wintering palms, hibiscus and bananas. My goal was to nurse them through the winter. My bananas push a new leaf every 14 - 17 days and the palms have all pushed new fronds and spears all winter. I do not have very good natural light but the CFL's seem to do just fine as a compliment to what little natural light I have. For this year at least, I had limited space and had to spread the plants out into 5 different locations. So I had to find a reasonable and cost effective way to get the plants through winter. It has seemed to work for me.
