I bought a light meter. Now what?

A year or so ago, I purchased an Apogee light meter when the society had a group buy. I never saw any discussions on how people were using them or how to interpret the results. So, has anyone used a meter to determine if lights need replacing or for coral placement?

I'm sure I've got a thread about how to use a PAR meter here on the site, as well as in one of our newsletters.

Hopefully this will help some: http://www.dfwmas.org/Newsletters/archive/2008/june.pdf
