You mean, stunning pictures, or stunning tanks ? There migth be a huge
difference in the way photographic film (or CCD detectors in digital
cameras) interpret the light from a triphosphor bulb, as compared with
the way our eyes interpret it. It could be that the pictures look very
different, but the actual visual appearance of the tanks wouldn't be that

I reply:

So true, but since I have never seen a high quality tank except in pictures
I have no way of knowing if this is the case and I am still left wondering
if wide spectrum or at least continuous spectrum lamps are better than
triphosphors for growing plants. It is also possible that some of the
stunning pictures are a result a very temporary tank condition. Maybe the
night before the guy uprooted all his plants replanted the tops and very
artfully arranged everything for a picture the next day.
