I think the question is why the upgrade? 130 PC is fine on a 20 unless your changing themes, and then the only real step up is a MH pendent (150 HQI). If your just looking for a nicer fixture, there are quite a few out there but none that I know of with 3 bulbs in it. I have a 20 and I like the 130W coralife lunar aqualight I own.
