Actually, weather he did any scientific tests or not, he is in fact
correct, BUT if he was scuba diving around a reef (salt water) the color
penetrations are differant than in fresh water. I get confusssed about
which is which, but I think it was the reds that dont penetrate very far in
the sea and the blues that dont penetrate well in fresh water. These are at
depths greater than most of your home aquariums though so it may or may not
make that much differance. Personally, the best lamps I've used to date
taking all things into concideration (cost of replacement, plant growth,
etc) are the standard cool white $0.89 each at the hardware store bulbs
replaced on a 1 year cycle (actualy since I have 6 F40-T12 or equivalent, I
change one every 2 months). Granted, my tanks aren't quite as good as the
photos I've seen, but are getting closer. :)
