Ok, what you can do then is keep your 2x250w + VHO fixture, hang that on half the tank. Then get a bare bones fixture, put in your two pendant bulbs, and just add VHO. This way all you are buying is some VHO, and a fixture.

I must be confusing. I already have 2 X Luminarc 111 pendants

with the connections and ballasts. I will be adding another 2 (I think), selling the 250W fixture and wondered how I would incorporate some VHO actinic lighting into this set up.

You currently have 2 pendants of MH, AND a fixture with 2 MH + VHO, is that correct?

If that is the case, buy a bare bones fixture to put the 2 pendants into, and add VHO to it. Then you will have 2 fixtures, each with MH + VHO in them, and that will be perfect coverage for a 4x4

These are big reflectors - approx. 20" X 20" so I don't think that a barebones fixture box is available - besides which I would have no idea how to put the thing together. I was thinking that I could hang all 4 pendants and then somehow run a VHO fixture down the center.

It always seems to me that Ruth does the coolest stuff.

I totally agree. I'm drooling over those lumenarc pendants :razz: Too bad we couldn't get a group order on those suckers!

Well why didn't I think of that. Actually we probably can if there is enough interest. I still have to order a couple of more (complete with ballast etc.) so if you want I will contact them and see if they are interested in a group order? I know that they had one going on Zeovit (that of course I missed out on).
These are supposed to be amazing reflectors and I know that the 2 I already have are pretty sweet.

Yeah that would be fantastic!! :mrgreen:

BTW, we should ask Psyire, he did a group order of Lumenarcs last year at some point. Maybe he could give us some ideas on the volume we have to move to get the deals.

Lumenarcs group order eh? Hmmm *goes to count his pennies*

You can hang VHO fixtures in-between the pendants, but 1 down the center will miss some area along the sides. You could also hang multiple VHO fixtures. The best looking would be 1 giant hood/cabinet fixture with vho and your large 20x20 reflectors mounted inside.
