Martin, you may be the dude I've been wanting to talk to. None of the
full-spectrum type bulbs have meaningful technical information on the
packages, such as a spectral analysis. Are such analyses easily available at
a web site or some such? Or should I feel lucky that a week ago I guessed
that the "Sunlight" bulbs are better than others? I'm aching for a
meaningful presentation of action spectra on such bulbs, odd as it may
seem... (show me your nanometers!).
