Is a $20 bulb every year really worth it? Run it 24 hours a day.

is it wise to run the UV steralizer 24 hours a day? assuming that you only
desire a 99.9% steralization rate you don't have to run the steralizer
that
much (depending upon gph through the steralizer and tank size). I've
read:

9.2 * (tank size / gph through steralizer) = hours a day UV steralizer
must
be on to attain 99.9% steralization rate (assuming uniform mixing). This
said my calculation is at most 7 hours a day, should I just run it for 8
hours a day and save my bulb life and power bill?

Should I run it 24 hours a day to achieve 99.999% steralization or for 8
hours a day?
