How about 55w bulbs on 36w ballests??

[skwirl]

i pretty sure you can run anything smaller than the ballast rating.

Great, so is that called over driving ur bulbs when ballests r bigger?????

PC bulbs will only draw whatever power it takes to drive them. Putting them on a larger ballast will not overdrive them. I run 2x32w on a 2x65w ballast over my refugium to grow macroalgae.
