Philipps Advance Centium 80W T5HO ballast

[Klaw2474]

I'm planning to supplement my LEDs with T5Ho and have been compiling my list, but I can't seem to find a Philips Advance Centium 80W ballast. It seems they only go up to 54W? Am I missing something?

Did they have an 80W ballast once upon a time?
