None of the people I know believe that.

Then George Booth, I and a number of others have been pulling the wool over
a lot of people's eyes for a long time.

Good quality NO fluorescent bulbs will give you close to the same intensity
per watt as metal halides.  Energy efficient T-8's are actually even a
little better.

There are two excellent reasons to choose metal halide lighting.

1.  The tank has too little surface area to accomodate enough fluorescent
tubes to light the tank properly.

2.  The aquarist would prefer an open top system.

Beyond these, whether to use metal halides or fluorescents is totally up to
the desires of the individual aquarist.
