    Ausrufezeichen What is the need dimmer lambs?

    Hi eveyone,

    I need information for lightning. I have GHL Profilux II Plus. I want dimmer 4 T5 and T8 fluorecent lamp with it. But I don't know exactly what I need for this. I think I need another equipment exepct dimmer balast. For example do I need EVG-AP-2F?

    Yes, you will need EVG-AP2.

    On each EVG-AP2 you can connect 2 dimming ballasts (1 dimming ballast can light up 1,2,3 or 4 lamps, depending on the ballast).
    1-10V line from profilux goes to EVGS and from there to ballasts.
    The power cable goes also to EVGS and from there to ballasts.

    So, if you want 4 T5 light up in pairs, you will need 2 ballast (that can take 2 lamps each) & 1 EVG.
    If you want 4 T5 bulbs to be able to dimm each one alone, you will need 4 ballast (that can take 1 lamp each) and 2 EVGS.

    It is depending on your needs what exactly you will need, but with Profilux everything is possible.

    Thanks you Almost,
    Thanks for your reply. For 4 T5 and 2 T8 lamb do I have to use the following equipments?

    - OSRAM QTI Dali 2x36 T8 Lamp 1 item
    - OSRAM QTI Dali 2x21/39 T5 Lamp 2 item
    - GHL EVG-AP-2F 3 item

    Can you check it please?

    If T8 lamps are 36W each, then OSRAM QTI Dali 2x36 T8 Lamp will do.

    You will need 2x OSRAM QTI Dali 2x21/39 T5 Lamp because each one can hold 2x 21W or 2x 39W T5 (if your lamps are 21 or 39W).
    So, you will need 3 ballasts total.

    For the EVGS, sory I cann't help since I am using 1-10V ballasts in my system.

    Someone using Dali could help.

    Hello Erkan,
    to our EVG-AP you can connect 1-10V-ballasts, DALI ballasts are connected at our DALI-extension card, called "PLM-DALI".

    Dear Carolin,
    Thanks for your reply.What's your advice? Which one is better dali or 1-10V control system? As I see in its cataloque 50 lamp can be conneconnected at the same time. Also can I use it with osram dali balast?
    One more question is can I connect T5 and T8 balast at the same time to this unit?
    As I explained before for 4 T5 and 2 T8 lamp, one dali card will be enough?

    Thanks.

    Erkan.

    DALI is a control bus (approximately to a serial interface) for illumination. For DALI you have to buy a PLM-DALI.
    Therefore it doesen't matter what kind of lamp is connected, if connected to a DALI ballast.

    In an 1-10V system the illumination is simply controlled with a analog 1-10V signal. The ProfiLux has four built in 1-10V channels (so called L ports). If the ballast doesn't support shut off (lamp completely off at 0%) you need EVG-AP (single lamp) or EVG-AP2 (dual lamp).
