I run them for about a year also.

Does everyone change all bulbs at one time or stage them over a few weeks? Personally, I change them all at one time.

I have a rotating schedule. for 6 bulbs, 3 actinic + 3 daylight I replace the oldest actinic every 4 months and the oldest daylight every 8 months.
