On my light setup im driving 2 t12's with one 4 bulb ballast.......but my question is can i wire the bulbs in series?....and if so would i gain more output?....im confused in a way because one bulb at 4x power is more output than 2 bulbs at 2x power.......even though the subject says gulfcoast anyone can answer ofcourse

Depending on the bulb length. If you were to put two four foot bulbs in series for a total of eight foot bulb length, you'd surely burn the ballast in a matter of seconds.

To answer your question, though, yes you would gain considerably more output with the bulbs in series. But as long as the total length, in series, does not exceed the ballasts rating, you should be fine. So if the T12 bulbs you are using are 2 feet long (F20T12) then you should definitely wire them in series and power them 4x. You'll have some AMAZING output. Considerably more than two bulbs in parallel at 2x each.

Yeah, I'm currently running the same way as you - 4F32T8 ballast driving two 48" bulbs. Eventually, I'm going to buy another ballast just like this one and OD them 4x instead of 2x. But I definitely will need some fans at that point because the bulbs are getting toasty even at 2x!
