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?
