I've been investigating the neodymium filtered incandescents w/o finding
any practical comparisons with regard to metamerism, or even with general
regard to our "ink on white" UIG (although I was somewhat suspect about
"NeoLite" hype, "enhances colors"). In any case ... what I have found is
that these bulbs' spectrums could debatably be described as "broad
spectrum", but only relative to fluorescent spectra. The neodymium
filtering does not affect the long wavelengths generally, but rather, in
specific regions ... the broad spectrum has "holes" in it. I am still
interested in practical comparisons to Solux and other professional
illuminants.
