PC bulb lifespan
I have 65 watt bulbs in my fixture that are a year old now and was wondering when I should think about replacements.

about 3-6 months ago depending on how much you run them daily.

Mine are coming up to about 6 months and they are getting ready to get replaced. My white is turning yellow and the blue is turning green.

 Kinda need to add that at the beginning 
As supplemental lighting they are not as important, but I would still replace them once a year.

There's a couple different manufacturers that make them . Not sure how different they would be . Give it a try . The multi bulb may be a waste with the MH's though ? Just a thought . I'd just run the deep blue 460's

+1, you will likely find that a mix bulb will not nearly be as effective with MH as a single spectrum bulb.
