Hi All...

It's almost time to change the MH bulbs in my 48" Outer Orbit 150W hood (2x 150w DE HQI + actinics), and I think I want 15k (maybe 12k) bulbs, but want more par than they provide.

So, I thought if I upgraded the ballast to a 250w, I'd have almost as much par with 15k at 250w as 10k at 150w.

Has anyone successfully run 250w in a 150w system, or do I really need to upgrade the ballast? If I need the upgrade, does anyone know where I can find them?

Thanks!
Paul
