The reason I wrote that the light intensity is roughly tripled is because
not only do you get no loss due to reflection off of the water's surface in
the emersed leaves, but you also get the reflection from the water's
surface under the emersed leaves.  I've found that plants growing in these
conditions can make do with quite a bit less light than they normally
require to grow emersed.  The sumbersed growth of these same plants doesn't
seem to be hurt too much either.

Just relating my experience.
