    Default can the profilux 3 control a dimmable ballast for metal halides?

    hello.

    I have 6 x 150w metal halide fittings that i would like to use over a planted tank and i would like to have my P3 control them.

    The fittings currently have their standard ballasts that i will replace with a dimmable ballast.

    Is the P3 capable of controlling metal halide dimmable ballasts?

    Thank you.

    it depends wat the dim inputs to these ballasts are:

    profilux can handle , 0-10 v , PWM , DALI , etc...

    What mean is: It´s nearly no prob to connect and control a dimable ballast by the Profilux once you have one.

    Your main problem is to find a capable ballast that can handle your metal halides - you should fix that prob first

    Thanks.

    Do you know if I can use a single 1000w ballast?

    150w X 6 lights = 900w.

    Is this right?

    Thanks

    No idea. You have to ask the lamp manufacturer if it´s possible to dim the lamps you have in general.
    Dimming of metal halide lamps is not that easy. Most of them (especially older ones) are not dimable. I don´t think it´s possible to dim more than one lamp with a single ballast, but this is only an assumption.

    Asking the manufacturer is a must! We can´t help you for that. If you have a working ballast, we can go further to connect it to the Profilux.

    The shown ballasts are not controllable by any external device. Sure, you can select one of three power stages with an internal switch, but it´s not possible to be controlled by an external signal. This three stage thing is nothing I wold call "dimable".

    OH!.....

    back to the drawing board.

    Im still researching.

    I didnt know what to ask for with regards to dimming so i couldnt tell the manufacturer exactly what i needed but now i know.

    I have a few more places to search.

    Ill be back!
