There are over 3500 lighting companies in the data base, and all have phone numbers but only a few have web site links. This is a resource site for the UK lighting industry, complete with Lighting News, a Product and Buyer's Guide and a Lighting Forum. At present not much to offer except several pages of industry related links. This is one long page of links, related mostly to optics, photometry and illuminating engineering. This is a general purpose lighting site with discussion groups, links and a book store for lighting related books.
Many important manufacturers seem to be missing - few links.
