Does anyone know of publically available data (either formulaic or just
plain numeric) regarding the spectral distributions for varying light
sources such as sunlight, clouded skylight, tungsten lighting, LED
lighting, fillament bulbs, candle light etc (accurate to 1 or ideally 1/2
nm)?

If the information is on the internet I am failing the google test to find
it... =(


Thanks in advance,

Most of the spectrums I have seen are graphical. There are some
programs that allow you to extract data from graphs. Unless there are
some people around that have tabular data, you might try this.

There was a public reference published some years ago with tabular spectral
data for general lighting lamps. I thought it was produced by NIST, but I
can't find it on the NIST site www.nist.gov It was great because the data
were a composite of the lamps from various manufacturers and it was reported
at 1 nm. intervals. I think the CIE has published something similar as
well. Maybe others can recall the references.

Ioannis Galidakis often participates in this group and has photographs
of spectra from several sources on his Web site. Using "ioannis
spectra" (no quotes) in Google gives Ioannis' page as the second hit
and http://members.misty.com/don/spectra.html from Don Klipstein as the
first hit. Don's page has a link to some NIST data at
http://physics.nist.gov/PhysRefData/contents-atomic.html . Ioannis'
pages are quite worthwhile by themselves and can be found at
http://ioannis.virtualcomposer2000.com/spectroscope/amici.html .
