My note was a response to Bill and the referenced article.

It is an article at a utility sponsored outreach lab, by highly
qualified staff. That article contains further references to a specific
paper as the basis for its conclusions.

Further information can be gathered from almost any reliable source,
i.e. universities, lamp manufacturers, books, but not third party
memories. The single largest source I am aware of, (since we are
dealing with many fine details that are well beyond the capacity of a
newsgroup,) is the Illuminating Engineering Society of North America:
www.iesna.org and its record of peer-reviewed papers that covers over
100 years of research from virtually all industry sources, currently
named LEUKOS.
