Giesemann Lighting Club.

One of the mh ballasts 'burnt out' ( I think ) on my 48" 2 x 250 hqi infiniti fixture. Trying to source a replacement is quite difficult. I have already tried working with aquarium specialty with no luck.

Can anyone help me out?

Next year I want to integrate two Kessil spotlight to run in addition to the mh, but not simultaneously.

Chris,

I am trying to place an order with some of the Giesemann INFINITI online vendors and nobody seems to know what ballasts options you guys have. Can you shine a little light on that?

Thanks,

John

John,

We are using the LuXcore ballasts for the Giesemann fixtures that have MH.

We have the plugs to mate to the Giesemann fixtures.

Does anyone know if the reflectors in the Moonlight are the same size as the reflectors in the Spectra ? The Moonlight reflectors appear to be larger than those in the Infinity but are they the same as the Spectra ? FWIW I'm trying to light a 40" wide tank and would like the dimming functions of the Moonlight but not at the expense of spread.
 
The reflectors in the Moonlight are indeed bigger than the Infiniti, however they're not quite as big as what the Spectra reflectors are. If you're wanting to stay with double ended lamps and need the maximum amount of light spread then the Moonlight would be the way to go. The downside to the Moonlight is that it's all internally ballasted though, which makes it very heavy and keeps a lot of heat above the water surface.

Personally, I'd go with the Spectra as it's going to give you even more spread, plus give you more bulb choices since it's a single ended fixture.

Thanks for the quick reply !
 
Just pick up a used Giesemann Infiniti 1 x 250 W 4 x 24 W T5 24", in excelllent condition.

This fixture will be used above a older Lamar 36x20x20 mainly lps , a few sticks.

Could not pass on this, came with bulbs, hanging kit & icecap m/h ballast at a great price.

May add some sup leds.

Are there any issues that i should be concerned with?

To replace bulbs , do i remove end cap with allen head screws?

Yes. I stripped mine and have since replaced with similar stainless phillips ones. You will also have to slide the grates and glass plates out.

So I am still one ballast short :mad2:

Chris, any updates on getting one? :idea:

Thanks,

PJ

For those of you who own the infinity 2x150Watt version who want to upgrade to 2 x 250 watt. I upgraded mine after an accident and it was pretty easy. just buy 2 x 250 watt clips, replace them, no mods to the reflector or fixture needed. Then replace the ballast! That's it!

I am trying to do the above conversion, can someone tell me what clips have to be changed per the above comment?

I am attempting to convert my Infiniti 150w to a 250w

Thanks,

John

Why is that? Otherwise it seems there's a lot of space between the separate color LEDs the Futura, which makes me wonder about possible disco effect. At the same time the Furura panels don't seem that large, which makes me wonder about light spread and possible coral self shadowing. Compare this with e.g. the GHL Mitras, where LEDs are arranged in tight clusters to prevent disco effect, while at the same time each cluster is separated from the other ones to prevent self shadowing.

(The above is just theoretical speculation, I haven't been able to actually see any of these fixtures in real life.)

I do think the Futura has the nicest looking enclosure design of the current LED fixtures, followed by the Powermodule.

Hi Christian.

I actually work with Giesemann on the development of the lighting systems but I'm based in the UK,

The Futura uses opticless format without secondary lenses, so each individual LED is emitting in a full 120deg range of spread. with each individual LED on each board overlapping its output within a very short distance of the board face, Each board then overlaps its neighbouring board to build up overall intensity without the need to focus light into shafts as it were. This also helps build a more uniform accumulation of light at depth without large fluctuations in intensity over short distances laterally, ( a common issue with lights using tight beam patterns) and helps reduce shading as more light is traveling at a wide range of angles including light bounced back from the internal faces of the tank.

We recently supplied several Futura units to a leading coral research facility who ran tests using some scarily clever and sensitive equipment and they were incredibly impressed by the units ability to blend output from multiple different frequency LED's within such a short distance (they actually tested down to within just 3" of the board face before experiencing any significant spotting)..at the recommended mounting height of 14cm to cover a 2ft front to back width applicable to their application all light was fully blended prior to entering the water surface.

Kind regards

That's interesting. Why release the Aurora then ?
