Ron Wozniuk has my vote. Maybe he could get together with Greg Tong if the latter is willing, and produce something ordered and manageable in size. Ballasts, lamps, sources, prices, and configurations for different sized tanks. For instance, I've yet to find an inexpensive generic MH lamp with a high CRI. Nor a satisfactory fluorescent solution to a six foot tank. The SP50's, are these Spectralites? -- Regards, Dave
