Today we have a lovely example of a 50W clear tubular HPS lamp.Here it is at full brightness.

As interesting as your lamp collection is I don't believe it is necessary to post both in a forum and on the gallery.The gallery is a much more sought out and effective means of sharing Photography. It is what people see when they first enter the site. This thread is a bit redundant and is not drawing much response from any other members. The forum is mostly meant for Q&A.
