The "full-spectrum" article in Wikipedia is a mess:

I normally wouldn't bother with it, but a link to one of my pages
appears there for some strange reason, and in general I feel that
the article relies too much on external links in order to explain
the story.

I think it is somewhat of a responsibility of ours to re-structure
this article. It is a shame for such a popular notion to not have a
respectable, reliable and scientific viewpoint from the guys here.

May I therefore suggest that we work on a draft here in s.e.l.,
which can later be posted into the Wiki page?

I don't want to do it myself because I am not a lighting engineer,
but if nobody else offers to start a draft, I will be glad to
summarize a preliminary version, which can be edited by others.

What say ye?


As a non-lighting engineer, may I ask a simple question in this
thread.

If a lamp is rated at a certain colour temperature then how is its
colour temperature determined from its spectrograph?

A spectrograph of a lamp's emissions seems to show there is a large
and complex number of peaks & troughs sometimes they are in bands
across its spectrum. This seems a tricky starting point.

What analysis is used to create a single colout temperature value
from the spectrum?

If only the spectra I have glanced at looked as simple as these!

I tend to think of something like this as a better representation:
