Are standard commercial metal halides http://www.qvsdirect.com/Low-Bay-Metal-Halide-Fitting-C-w-Lamp-Glass-400W-pr-18416.htmllike this going to work over a planted tank?
Is there much of a difference in the light source provided by metal halide and sodium bulbs in these bow type fittings?
any though? opinions gratefully received
