The message
from "The Medway Handyman" contains
these words:

I'd like to learn a bit more about fluorescent lights. Is there a web site
with any info that would help?

I'm sure someone will tell me that Wikipedia is crap[1] - but this has
quite a lot of info
http://en.wikipedia.org/wiki/Fluorescent_lamp

[1] And if they do they can go edit it.
