Wayne,
I probably should get you to come to my house one day to give me some pointers. I like my lights, but I don't think it's sufficient enough since I couldn't keep caps alive, the ONLY thing I couldn't keep in my bowfront. I have trouble trying to put anymore lights in my canopy since it is a bowfront. All I'm running is 2-250w XM-20k. The caps just doesn't look as pretty as my other tank running Actinics and 14k MH's. Maybe one of your retros would work???
