There is some benefit to having 2 fixtures like you mentioned. You could space them a little bit. However, I don't think it is "worth" it in the end. 1 48" fixture will look clean and have fewer T5s to replace each year.

My spectra has 3 cords on it. I think it was modded by the user before me. It has 1 for the MH and 1 for each bank of T5s. I don't run each T5 bank separately but certainly can if I want to.

I wonder if BRS can't get one in white for you? Not sure if you have asked them. Mine is the silver but I have seriously contemplated taking it all apart and making it black with some silver accents. It would take close to a full weekend I bet and I don't have an extra light or a full weekend.

@ReefCowboy I've seen another modification that puts an AI Hydra 26 in-between the halides. I'll be giving this a shot for my 48" Spectra soon.

Yes, Ive seen them. I ran MHs with Kessil A160's just for blues and it made the overall look really nice IMO. I think I would probably retrofit three A160's, one in each mesh section. Like stated in my past post, I just wonder how much these lights would suffer being inside the spectra fixture, close to MH's reflectors?
Last thing you want is a fire!

I hear Reefbrite will manufacture xho bkue led bars to fit replacing the T5's which is a nice project, but those leds dont really oack that much punch.
The kessils put out much nicer blue for dusk/dawn, but that is just my opinion.

I think the american market only gets black, period.
The black seems to be really nice also, but the glossy white is at another level to my taste!

[ReefCowboy]

Does anyone know if we will see shortages of Radium 250 w MH bulbs anytime in the near future? Ive read somewhere that the industry is pushing for the end of these bulbs, mainly ones used for lighting of factories and so forth. Not sure if we are at risk to lose them at the hobby level?

[mallard]

Mine has been modified with ATI T5 dimmable ballasts, so dusk/Dawn is handled by the T5's. For my setup, the LEDs are for a bit of pop and moonlights. Could be another option to consider.

If you really love the white, I'd go that route and import if you can.

I'm not sure how long they will be around but I bet by the time they are completely phased out, LEDs or something else will have really surpassed them. Heck the new Ecotech diffuser could be a game changer for all LEDs. I know they aren't the first but if a big name makes diffusing a popular option, others will follow.

Agree. If were to get the Spectra, would pack some bulbs up maybe for a good 3 years worth. To me the Radium is a must if I go MH.

In regards to the Radion diffusers, I know someone who saw them in person recently and he said the overall look of the corals and tank are very close to a MH

For those looking at the Genesis, it will be a lower cost replacement for the Aurora. They are passively cooled, so leds are dialed down to only 50% of the vervve.

Like ive posted previously, ive seen it in person and to be honest found it underpowered. Take note deep tank owners

Since its been over a year since these were originally announced, I wonder if there will be any changes? Time will tell.

These will be perfect for my 300g FO tank...please dimmable T5s!!!

I want:

1. beautiful slow sunrise/sunset;
2. multiple channels for great color combinations that LEDs provide;
3. Excellent light distribution from T5 & LED combo;
4. Passive cooling...fans can become noisy;
5. Two 3 footers is fine for my 8 foot long peninsula tank;
6. Low wattage LEDs since I have excellent ambient light, I only want supplemental low watt colorful light;
7. dimmable T5s!


CAN'T WAIT

[ReefCowboy]

Dont get me wrong I LOVE giesemann fixtures. The one thing that worries me about the genesis is the same as with the spectra. Their T5's are passively cooled. As heat climbs throughout the hours of use, the efficiency of the T5 bulbs will drop. Giesemann packs their T5's even tighter to allow for a sleeker design making that contribute even further to poor heat management. The Matrixx(not related to the conversation)is a heatbox, by far nicer looking than the ATI, but puts out way less par due to heat issues.

With the Spectra, those two MH reflectors are doing all the heavy lifting. T5's are just for taste of blues, so I could care less about that issue. Corals are covered.

Someone using the Genesis(not you since you will run a FOWLR) keeping corals counting on the T5 par can be misled, if the tank is deep. For fish only tanks, that unit is a slam dunk though for sure.

I could be wrong once we see par ratings of that unit(BRS testing hopefully), maybe the 50% capacity on the leds are still plenty.

Nonetheless, I love hybrid units, and think we all get advantages having them as options in the market

FWIW, I turn my T5s off when the halide is on. The Radium had amazing color without any supplement so I let the T5s cool off for those hours and then only run them before and after

That is why Radiums are it.
Beautiful light

[Jimbo327]

Anyone run their Geisemann Matrixx II T5 only fixture without the splash shield? BRS had a youtube video that said that worked really well in their testing. Not exactly sure what that means or how many % improvement. If some other PAR testing was done, please point me to it. Thanks!

Im using a 72" giesemann infinity light fixture 3- phoenix 250w 14k bulbs and 4 60" 80 watt t5's.. 2 of the t5's are ATI blue + and the other 2 are actinic+ bulbs

I'm currently running this light fixture above a 220 gallon reeftank 72" x 24" x 30" I just recently put in some sps frags and they are having a very hard time adjusting to this light. They lost most of their color withing 2 weeks and I'm thinking this light might be too much for them. Currently my light fixture is 10" off the water surface and the time schedule is:
actinic on at 10am
Mh on at noon
Mh off at 6pm
Actinic off at 8pm
Does anyone have any ideas what i can possibly do? Hate to reduce light schedule even more but will if i have to.

6 hrs of halide from the get go is a lot of punch. Plus blue + puts out lots of par.
You are def bleaching your corals.
Lower MH to 3 hrs and lower t5's to 6 hrs. Raise the fixture above the tank for a few weeks until you notice colors coming back.

[ReefCowboy]

Bit the bullet and bought the Spectra for my next build! Ive always wanted to run this unit, IMO the holy grail of reef lighting. Having ran T5's Leds, Leds again, Hybrids...Halides have given me by far the best sps results.

The tank is still a few months out from water but its nice to know lighting is covered.

[rtparty]

Awesome ReefCowboy! You are going to love it. MH/T5 is by far my favorite lighting I've ever used and I've used almost everything. MH only, power compact, T5s, LEDs and T5/LED hybrid. T5 only is also great IMO. It just lacks shimmer but colors are amazing.

Adding some LEDs to my current setup would make it a little better since blue LEDs create an amazing pop

[moondoggy4]

Great light Cowboy, congrats.

[ReefCowboy]

Moondoggy, Rtparty,

Thank you! I know I will like this unit, while running Sunpowers, Orphek, Radion G4's, I had kept an eye on this forum waiting for the right build to end up with the Spectra!

Im on the look out now for some blue led supplementation. Really wonder if the new Euroquatics E5X T5/led bulbs would work well enough with it?

RtParty,

What are your plans with supplementation?

The LED T5 bulbs are on my radar but I am afraid of the heat and killing the LEDs.

If I can find a Reefbrite locally that I can borrow I'll attach it and see if it totally ruins the look.

I've also thought about the Kessil A80 attached to the "mesh" grill. It shouldn't stick down too bad or I can cut holes in the mesh and hide them in the fixture. Again, heat would be my concern here. The RB strip would at least be away from the halide so while might diminish the look, I know the LEDs will be safe.

The kessil are in my mind also(A160's)I thought of running them around the halides only, meaning they ramp up and shut off right after the halides go on. Then turn on right before the halides turn off and ramp down by themselves. I guess that way at least the leds are running with less heat inside the fixture? Maybe I should do A160's on the sides and an A360 in the middle...What are your thoughts?

The reefbrites do ok job IMO, not bright enough for a nice pop such as the kessils. If you get silver reefbrites, should be able to blend them nicely with the spectra.

Yeah the a160s will work as well and it has been shown it can be done with a lot of work and modding of the fixture. Not sure if I want to go that far when a Reefbrite just bolts right on with very little work. I am not worried how they look with the halide on since I will only run the LEDs during dusk/dawn and to see that blue pop.

I am not sure if the heat only kills LEDs if they are running or if they are "safe" if turned off.

The LED T5 bulbs would probably be the easiest and cheapest route for both of us. I know the new version has been made stronger and brighter so that would help. I'd replace my Blue Plus bulbs and leave my Actinic. Hmm, maybe I need to find one and at least try it out

If you try the led t5 bulbs pls give us a reciew. I need more pop in my setup as well and wondering what combo of blue+ and actinic+ and led t5 would be required to pop those colors
