Thanks for the concern, my tank is just fine as far as I can tell. I retrofitted the stock hoods with four candelabra bases and am using four 13w compact fluorescents. Both my Anubias are pushing new leaves only a few days after the switch.

What I was proposing was more along the lines of a paradigm shift in talking about lighting, since arc sources are more efficient than fluorescents which are still more efficient than tungsten sources.

That way I can still be a watt-miser and have a tank bright enough for cool plants.
