[ebaygul]

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.

Hi Almost,
Which one can I use for EVG-AP-2F, 1-10v control or DALI balast?
Thanks.

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