While in the process of Signing Off the List I saw an interesting message
comparing light from tungsten (common) light bulbs and flourescent.

Although the flourescent light may LOOK bluer, I recall studying
photographic film information indicating that standard flourescent light
bulbs are missing some rather narrow bands of color in the red and green
regions.  Of course there are quite a variety of colors of flourescent
light available now.  I believe I have read that the Grow Light types for
plants are not true full spectrum.

I have seen one brand called Vita-Light (or Vita-Lite?) that claims to be
full spectrum.  At the grocery store today I was surprised at how
luscious looking the color of produce was and looked at the type of bulbs
they were using above it.  I was surprised to see they were Vita-Lights
because I know they are more expensive.

(Thanks to all those who have offered the useful information that I have
read while being on the list!)
