Well, there's the thread that Alex started, where he contributed some interesting photos of "something wrong" with plants under two big 42-watt warm white CFL bulbs.
The thread "warm white: bad for plants period???" in

And the thread "Indoor Lights", started by

Generally, I defer to
@drdawg / Ken Ramsey and
@psa / Paul Anguiano and
@kqcrna / Karen (and others) about plant lighting because they have experience, and I mostly have reading plus a very little 20-30 year old experience.
That blog article was where I gave up on making an article, because I couldn't find spectra that would prove that expensive "gro lites" are really just relabeled broad spectrum tri-phosphor tubes with high prices. And I found contradictory info about using T8 bulbs in T-12 fixtures (suitability of old-style ballasts with T-8 bulbs).
