Profilux II plus aquarium controller

[Matthias Gross]

Hi Ginzo

" Can you explain to me how the dimming lights work ? For example, currently I have two Giesemann Nova II lamps (150 watts HQI) with electronic balast. Will I be able to dimm those lights ? If yes, what is required ?"
as Marc wrote MH can't be dimmed

"Also, I'm looking at purchasing 2 Sunlight Supply 36" Ready Fit T5 Retrofit Fixtures (2-bulb, 2x39W). It comes completely assembled with TEK Reflectors and a 8' power cord. Features a major brand ballast. My question is, will I be able to dimm those T5 Fixtures with the Profilux II controller, if yes do I have to purchase an extra ballast..or anything else ?"
Marc: There is no need for additional cards when you want to control a dimmable lamp. ProfIlux has 4x 1-10V outputs (dimming control signals) on board.
Ginzo: If your lamp has dimmable ballasts you just need an interface between ProfiLux and ballast. If not: Replace the ballast.
