Alert just saw a few Giesemanns on Ebay Spectra 24" 400W and Infinity located on east coast.

[salasaz]

nice might be looking into one of these fixtures for a 5 foot 125 gal. Kind of worried about acrylic with halides over it. Anyone running halides over an acrylic tank? thanks for the feedback!

[ReefCowboy]

Im not an Led guy, and def do not like any of the set ups out there. I was at Manhattan Aquariums in NYC today and saw a Giessman Led fixture, and was very amazed by the light put out. It was pricy, 48" for $2,599.00. The reason it caught my attention was the light put by the fixture...was def not like the radions, or AI's none if them looked like this one.

It had four light sources and the type of overall light seemed like MH? I mean the light was spread wide...beautiful light.

Not that i would buy it, trust me my next light will be mh+t5, but i wanted to ask if anyone had seen this light out yet?

Here it is. Futura. Check out the video, definitely worth it pretty impressive

How heavy are the 24 inch Infiniti models? I've been searching and can't seem to locate that info online. I'm trying to figure out if my light bracket can handle the weight.

It is 14 1/2 pounds. For a 24'' model.

Where can you buy replacement 250w ballast for the infiniti???

[loweryster]

I would not replace it, I would upgrade it. When I had an Infiniti they used a step transformer to bring the voltage to 230V and ballast and ignitor were inside the fixture. Not sure what your setup is. I would opt for an E-ballast like a Lumitek and bypass all the Giesemann electronics. It's quite simple to do. Here is a really old thread I started.

thanks for the link for your right up I have a 24'' Infinity with 150 4 t-5 I have three wires coming out of the unit.
I have ask several times other people, Where does the hanging kit actually attache the light fixture? how does it attache? Thanks in advance
Is the giesemann 150 ballast a M81 ballast?
Thanks in advance

[loweryster]

I recall a slit on top of the fixture that 2 nuts road in. Then you would thread the hanging kit into it. Don't know what the ballast was.

[banira]

Hi,
Does anyone have a matrixx 2? How satisfied are you with this unit?

Cheers ��☺

Thanks I cannot seem to find those nuts I noticed in my light I have two metal squares slides I guess that is where you screw it in, problem they are a different size then the hanging kit. Does this sounds correct?

[loweryster]

Yeah now that I think about it they might of been squares. If those are still sliding around in there you should be good. I would contact Xenia North America http://www.xeniainc.com/
There was a guy there named Phil Gilbert who always took care of me. He should have a hanging kit for you.

[moondoggy4]

Thanks JL

[loweryster]

You bet!

Question for you spectra owners out there - do any of you control the lighting of the individual T5's with a neptune Apex (you know - to give a "ramp up" and "ramp down" by turning them on individually?)

Not looking for T5 Dimming - just how you control each of the indivual t5's.

Thanks!

Unless you were to splice the cords you cant control them individually. Only 2 at a time the way it is wired.(at least on mine)

I have the back 2 T5's come on first, then 2 hours later the front 2 come on.

[Ted_C]

yes - your right - I mis-read the specifications. I'm still looking to purchase actually. Thanks for the reply

so - making an assumption here - you just control them via the apex by turning power on and off to the outlets - not by any special module that hooks into the wiring of the spectra.

Yes same with my unit but I have been wondering the same thing can we dim the ballast's with the APEX? so two come on slow then the next two or can we only turn on and off. Not sure if the Giesemann ballast is able to be dimmed.

[Ted_C]

I do beleive you need special ballasts to be able to dim them - according to premium aquatics - it looks like it's another $499 upgrade to the fixture

http://reefcentral.com/forums//showthread.php?t=2373363

If you have this package - I beleive you'll need the VDM module or the full version of the apex (i.e. not Jr or Lite).

[dowtish]

I have icecap ballasts on my fixture and have never thought about dimming the T5 bulbs. you would definitely need a ballast capable and a VDM module for the APEX. I have a blue LED strip on my tank in addition to the spectra that is dimmable that I use for ramping up and down, so I guess thats why I never considered dimming the T5's.

Just joined the club today. I love the lights, but my issue is I want a better dawn/dusk simulation than just turning off and on the front and back of the lighting. I feel that if I could rewire the T5 so that a pair of inner and then a pair of outer lights turn on and off that would be an improvement. Has anyone opened up the guts enough to see if this is doable without a major amount of electrical work?

Thanks to any and all that can help.

The answer to that is Yes, I believe that answer is in this thread I believe, I have the Infinity model and I can do two T-5's at a time twice and the MH so three different controls.

Here is the thread on re wiring your Giesemann light thanks JL

Thanks for the link! I was just about to search for it; I knew I had seen that thread before but I didn't bookmark it. Lucky for me the Spectra does come with pairing done front to back to I have some ability right now, but I'd rather have the pairing done inners and outers. I may yet give a try at rewiring, the primary question would be whether or not the wires are long enough to reach across. My guess is they are not so I would need to add some wiring. Not a huge deal, but still not super simple. We'll see. I'm taking down one fixture today to put Radiums in so maybe I'll have a look then.

Thanks again.
