Once a year. I know because Jenn of IO told me so, and I trust her

This also depends on if you over drive your bulbs because if I remember correctly over driving causes the life span of the bulb to be shortened.

Also be sure that you acclimate the corals to the new bulbs as well as they will be putting out more light and you will have to adjust your photo period or the corals to the change.

I know I am pretty alone with this idea - but I change them when they blow up...

I chage mine out one at a time to minimize the shock, with about two weeks between bulbs.

That works out fine... they never blow up all at once!
