How do you know if it's time to replace a UV lamp?

Yeah manufacturers will likely state longer bulb life just like 12 months for Halides and 18 months for T5s which isn't the case if you want to keep your par levels up.

that depends a lot on the type/brand of bulb and the ballast it is run on.

I know that AB10K SE run on a M80 ballast will only lose about 15% in two years.
