There used to be quite a useful collection over at lighting-materials.com / spectraldb.com but the sites are now down. Just wondering if anybody knows where these repositories now exist?
Unfortunately, those did not survive @J_Alstan_Jakubiecās transition to Toronto. =( He has said that he has plans to reconstitute and build upon that work, though not sure of the timeline.

Thank you @Rob_Guglielmetti.
@J_Alstan_Jakubiec by the way if you need any help by way of free server hosting or a mirror of your site when you have time to reconstruct the site, Iād be more than happy to help 
Hi all,
Thanks for noticing the site was gone at all 
. I hope to have it back online by mid-summer, with some new measured data too.

I was perhaps a little optimistic on my timeline for the Summer, but the website is finally live again at http://spectraldb.com/! I notice that it hangs for a few seconds sometimes when loading in Chrome, but I have not figured out why yet.

It worked great on my Firefox.
