From what I found with my research into lights this spring it was the T12's
that dropped to 65%+- of their original light output in 6 months, T8's went
to 90%+- in that time frame and the compacts only dropped to 97%+-. That's
one of the reason's I was first trying to short high output T8's for my 27G.

standard flourescents every six months and compact flourescent every
eighteen months. It takes a few years, and they're a little harder to
find,
