I posted on RC that I plan on swapping out my 24" 24W T5HO grow lamps every 3 months. Someone thought that rule only applied to CFLs andthat T5s in a scrubber should last longer. What schedule should I follow here? These are the lamps I'm using:

They're only $4/ea in an 8 pack so not like it's breaking the budget.
