I have to disagree. 7 watts is the amount that the bulb consumes in energy,

That's not my point. As I said, in AQUARIUM-speak, when people say "you need
2 watts/gallon to grow plants" what they mean is fluorescent watts.
You might not agree with the terminology, but that's the way things are.

If we knew what we were doing it would not be called research, would it?

I get your point. What we have to clear up here is that it's not a strip (tube)
light like a fluorescent fixture. The bulb I have is an energy save bulb. It
takes 7 watts of power but emits light like a 30 watt fluorescent light. This is
why we cannot compare them to fluorescent tubes. I think the biggest they have
in those energy savers is a 25 watt bulb, but it emits like a 100 watt bulb. I
also have a 14 watt and it's WAY too bright, my fish hide because it's too
bright.
