AB bulbs fire for only 1 min?

[wrott]

I've been running reeflux bulbs and I've run Ushios,Hamiltons and XMs before, but my new Aqualine Bushes(sp?) fire for only 1-2 minutes, then shut off?
Which parts of my PFO ballasts do I need to relpace?
thanks for all sugestions, Rod

Oh, and they re-fire every 15 min then shut off after a minute.

AB bulbs require a pulse start ballast to fire properly. If you just have standard PFOs, they are more than likely probe start ballasts. If the bulbs do manage to fire on a probe start, their performance can be rather inconsistent (which it sounds like you are experiencing). Unfortunately you will probably need to either find a different brand of bulbs or change your ballasts.

Edit: Forgot to add the ABs can also be run on HQI and electronic ballasts

Thanks mr294, is it possible to modify a standard ballast to pulse start?
