It may be well known to you, but you don't have the two lamps near side
by side to make a comparison.

I think maybe the belief that fluos have a green cast comes from the was
film and sensors respond to their spectrum.

It is certainly a lot more exaggerated on colour slide film (especially
Kodachrome) than to the naked eye. Colour negative film is affected too, but
most print labs correct for colour cast. I remember taking two photos on
colour neg, one by fluorescent light and one by tungsten light, without any
colour-correction filters. Apart from differences in the shadows and
reflections off shiny objects, the two prints were pretty much
indistinguishable, even though there was a big difference in the negatives.

I've not seen the green cast with fluorescent lights with a digital camera.
Depending on what colour temperature preset you use, you get either an
orange cast or a blue cast (or no discernable cast), but never a green one.
So there's something about digital sensors which means they don't suffer
from it to the same extent - or else if it present at the sensor, it is
automatically corrected by the sensor-processing. That is true of "raw" DNG
files, as well as JPG which may have some normalisations.
