About the same as fluorescents, I would guess. The Lancaster article shows
them as slightly more efficient, but the shape factor is less efficient for
rectangular tanks.

I would plan on at least 2W/G, and then put up with less than bright
corners. IDK if others with experience with them agree or not. [I have
none.]
