ATI Sirius X Lights

Do you think the fixture is cool enough to mount inside (or at least hidden by) a canopy?

I don't think I'd try my t5 powermodule inside anything...
 
I'm sure this is a great light and I'm sure we'll see other manufacturers bringing LED fixtures with a broader spread to the market.

I've accomplished the same thing for the last couple of years by simply combining a pair of the Kessils A350Ws with a Reefbrite XHO blue.

I have a nice shimmer from the Kessils with controllable color and intensity. The Reefbrite XHO blue fills in like a T5 actinic or Blue+ would and eliminates any shadowing. I also don't have to hang anything from the ceiling.

Your concoction is more expensive and no where near as efficient in reference to par and coverage. Why bother posting in this thread?

It's inferior on so many levels it's not even funny. I would suggest a separate thread for such comparisons.

Damn. Do I have to break it my corals ?

They've been growing wonderfully under my inferior lighting for a couple of years before ATI brought out the Sirius X.

They'll be sad. :eek2:

yes the steering is just about light. Here reflectors are used yes and no lenses. That is, the light is directed and not bundled.

Not sure I understood this. How are reflectors used inside the Sirius X (or with LED lights in general)? I though reflectors were not needed with LEDs?
 
It's becoming more evident that reflectors are useful for LEDs and that lenses were more of a marketing plow to distinguish itself differently from metal halide. ATI uses reflectors, the next maxspect fixture will be reflector based as well

Well, it is a a popular fallacy that no reflectors are needed. If you make PAR-measuremants below a pendant the truth is a complete different story.
For example:
If we would remove the Reflectors on our Sirius, we lose min. 30% in a wide area below the pendant. If you dont use reflectors you lose a part of the side scattered light. This is waste of energy. So, in our opinion (ATI) using LEDs for Aquaria in order to safe energy and not using Reflectors is contradiction in terms. This are the results from our lab. 30% loses in efficiency are not acceptable in our opinion....

The main funktion of a reflector is to direct the light to the area where the light is needed without producing so called "Hotspots". Our computer optimised Reflektor "catch" the side scattered light that comes from the LED and direct it into the aquaria. In this way we take advantage of the otherwise lost radiation (side scattered light). At best the reflector catch every Photon comming from the LED and direct this photon to our corals. The secret is to do this without generating "Hotspots" or smal areas with higher par readings. Here the sheeps are seperated from the goats. A Reflecors has to generate an even light distribution.

Otherwise you are always limited by the Hotspots and you have to reduce the complete light output of the LED-fixture in order not to risk or burn your corals.
This is the reason why an even light distribution is so incredible important. If you have "Hotspots" you cant use the full potential of the LED-Fixture.

So, there are technical reasons to use Reflectors (Lighting efficiency or coefficient of utilization) and we have biological reasons to generate an even light distribution to our corals.

These are the simple reasons why we work with Reflectors on LEDs from the first hour.

Thanks.

Oliver,

Does the latest software update include full moon phase simulation and if not does ATI have any plans to include moon phase control in the future? Do the newest Powermodules have the same LED reflector in their design? Is the Sirius available in the US now?

Thank you for creating such great cutting edge technology!
 
Hi Joe,

well, we are using the same optimised Reflectors in our Sirius and our LED-Powermodul or Hybrid. Once something is optimised it makes no sence to use something different in our Products. This is the reason why we use silver coated reflectors in all our T5-fixtures for example etc.

The Sirius is available in the US now. I guess ATI Northamerica has some in Stock.

You can simulate the moon by dimming the royalblue channel on 1% in the night for example. But we dont have a full moon simultaion right now. But maybe we will have something like this in the near future. To be honest: A full moon simulation had not our highest priority.

regards,
Oliver

I'm considering a X4 over my 100 x 90 x 50 cm mixed lps / sps reef. Tank is centrally scaped with 2 x islands, sps on the islands, lps on the edges of the islands, no corals outside approx 85 x 70 cm. What do you think?

Hi Mike,

one of our dealers in Germany made a new Showtank with our Sirius x4. This Tank is 130cm long and 60 cm wide. Here you can find some pictures of this tank:

He made a video, too: http://www.youtube.com/watch?v=nEA0beyzoh4

I hope this helps to give you a better Idea. As mentioned before the Reflectors in our Sirius are designed to generate an even and wide light distribution and I think that the Sirius x4 will do a good job on your tank with centrally scaped Islands.

Oliver

Alas it seems to be quite a bit of disco effect on the sandbed:

DSC_0084_016_zps320b8554.jpg


The pictures with less red light are not as bad, but you can still see it in the corners, except in the overexposed picture.

The video is also very overexposed.
 
Hello Christian,

normally you dont see a Disco ball effect. I guess that this dealer use way too much red. You only have a Effekt like this in Corners if you really use too much red.

Thousand of People at Interzoo could see that our Sirius dont not generate effects like this.

Also, using too much red is very dangerous. We recommand to use red at max. 25-30%. Otherwise we may see negative effects on corals. The red channel is only to make some little cosmetic effect if wanted. Corals dont really need red light. Please Keep this in mind....

Here is another Video from the owner of a german Forum showing the x8 in Demo mode...

Sorry for the bad quaitity. But all the Videos are made from other persons. We are designing a new webside and we will have profesional videos on our webside soon.

Does anyone actually own or have experience of the Sirius? Really tempted on the X4 for my 100 x 90 x 50 cm cube, but living in Norway l'm not going to get to see before l buy......
 
Ordered a Sirius X4 from Germany some days back, l´m English and l live in Norway. l specifically asked the outlet to ensure English instructions were included, they were to inform ATI of my request. l have since been told that the light is despatched but ATI have no manual in English for the light. You people in the USA with this light, how did you get on for a manual? Can English be selected on the control panel? Or do l have to pester my wife to think back 30 yrs to her 2 years of high school German?

Thanks in Advance

Mike

I'm not sure I have seen a person from the US state they have one. It is possible "yitman" is from the US. Our biggest importer ReefGeek has gone out of business to boot or I'd say contact them. I'm sure Oliver will chime in soon and help.
