White light sources (and their quality)

Question

(continued from another thread)
White LEDs are currently not a great way to illuminate your prints because they are not near full spectrum light sources.  Most "white" LEDs are currently blue or violet LEDs with a green or yellow phosphor added to look neutral - but they have very little light in other areas (especially red).  Some high end white LEDs are getting closer to full spectrum - but those are only recently available, and are not yet widespread.
Cheap fluorescent lamps tend to have a few "spikes" of light and have some wavelenths almost entirely missing.  "Full Spectrum" Fluorescent lights are getting better, and cheaper - but are still not comparable in quality to tungsten or daylight.
Spectra measured with X-Rite ColorMunki and Argyll CMS spotread utility. Multiple readings averaged, normalized and plotted in Microsoft Excel.

Some additional information (2006):
(1) shows spectra for proofing light by Just (fluorescent) and Solux (tungsten)
and related topics.
(2) shows spectra for commercial fluorescent tubes.
Illuminance E (lux, lx) and luminance L (candela/m², cd/m²) can be related only under
certain assumptions (isotropic diffuser). The one gets (Hunt, Measuring Colour):
L / (cd / m²) = (1/pi) E / lx
or simplified 
L = E / 3
Monitor           L = 100 cd/m² (luminance)
Office desktop E = 500 lx      (illuminance)
Proofing light  E = 2000 lx  (according to some standard for critical inspection)
We can see immediately, applying the rule of thumb, that paper prints cannot
be viewed side by side with monitors with good results:
2000/3 = 666 (print)  <---->  100 (monitor)
The ambient light at the working place in my environment is about 50 lx !
Proofing light is available in a neighbour room.
