I use a 250 for a macro tank, I only run 2 of the 6 t5 bulbs, why would this be bad for the ballast?
It is not.
Since posting that, I have done a little reading... Flourescent bulbs do not draw power the same way an incandescent bulb does. To put it simply, the ballast controls the power supplied to the bulbs. Therefore, weather or not a bulb is in the socket is irrelevant.
Running fewer bulbs in the fixture will NOT hurt the ballasts or fixture.
