oh ok. yeah i have been asking sam and wondering why the nova A6 are split up 48/24. he has yet to respond yet.

dimmer 1 controls 48
dimmer 2 controls 24

i dont understand why they cant wire them to both control the same amount of leds. because of this i have had a hard time figuring out what mix i would want.

i think i might rather have the A4, at least those have an equal dimmer control.

The drivers might actually be. We don't know if they are yet.

They are probably lookin at the 24 LED's as a Dawn to Dusk circuit and the 48 LED's as a mid day circuit. Some manufacturers do the same with T-5's 2 bulbs for dawn to to Dusk and 4 or 6 more for Mid Day.

With that thinking you put mainly the blues on the 24 circuit with only enough whites to break that all blue windex look. Then put the rest of the blues and whites on the 48 LED circuit.

Travis1787 · 05/21/2012, 11:03 AM

Just like I thought sam is gonna make sure youits how I wanted it exactly. Sam is the man of course lol

When will we know? That's what I'm waiting.. I want to 3xA8s and dimmable control via apex.

bhazard451 · 05/21/2012, 11:06 AM

what do you think is a better option? sam sent me these as options.

Option ONE:
Dimming 1: 36 blue + 10 white + 2 UV;
Dimming 2: 20 white + 4 UV

Option Two:
Dimming 1: 24 blue
Dimming 2: 30 white + 12 blue + 6 UV

or is there something else that you might go with? thanks.

Since you are dealing directly with one of the factories that makes them, you have more options available. Shipping is incredibly quick too. My unit shipped friday and is on delivery to me today. That is just silly quick from Hong Kong. I don't even get most US deliveries that quick.

Wait, so I can get this custom made with cree leds?

Yes. You would have to email them, and it would cost more.

rad1687 · 05/21/2012, 06:44 PM

Someone please open up a 120w! I am so curious about the possibility of adding a controller!

Right, what I'm saying that the manufacturer should have that option to add. I'm sure that many people wouldn't mind to pay a little extra for that.

I already asked but they do not offer it. They might in the future, but don't expect it anytime soon.

sent an email for getting 3 fixtures (lighting a 92 corner, complete pain in the butt) waiting on pricing information back. If the price is right... hello new lighting!!!

Amoore311 · 05/22/2012, 06:47 AM

If these end up being Apex Controllable I'm ordering 2 right away lol.

If those were my only options I would go with option #2

However if could customize any way I wanted with those LED's I'd go

Circuit 1 dawn to Dusk
4 UV, 4 Whites, 16 Blues. (this would be predominantly blue with just enough white to break the windex look)

Circuit 2 Mid Day
2 UV's, 20 Blues, 26 Whites (this would increase the intensity for mid day and brighten thing up considerbly)

jefftse · 05/22/2012, 09:43 AM

i like option 2

AcroBluz · 05/22/2012, 09:47 AM

I have been looking at these lights and I would like someone to look at the links and let me know if I should customize these more or not. This will be my first LED fixture so I am not sure what ratios I should be getting.

First I was thinking of getting 5 of these ( 2 for my frag tank and 3 for my 150g display)
http://www.aliexpress.com/store/3178...-25-white.html

Then I was thinking I would get 2 of the 120w and 3 a4's for my display

http://www.aliexpress.com/store/3178...ight-3pcs.html

Which is a better option and should I do a different ratio then the 1:1?

a majority of the foreign manufacturers do use Bridgelux or other Chineese LED's. I would be skeptical when they do not list the manufacturer as there are some real poor ones there.

Cree is the highest rated for LED's. However Bridgelux and Philips Rebels fall a fairly close second. Then when you to some of the other LED manufacturers the quality starts varing all over the place. Some make a fantastic 10,00K LED but there blues are poor others are the other way around.

The reason Crees are used a lot is price. While a 60 LED Cree unit running at 150 Watts put out as much light as a 80 LED Bridglux running at 160 Watts the cost of the LED's themnselves is roughly 50% or more for the Cree LEDs.

Your fist link basicly sounds good however in reading the small print they claim they are using 10,00K to 20,000K Cree LED's. The highest Color temp of Cree LED's is 8,300K. I do like there neutral White LED's though when in a 3 blue to 1 white ratio.

The second link has me questioning what kind of LED's they are using. But they do have the option of being completly customizable.

My basic instinct would be to get fixtures for your frag tank then see hopw you like the color before getting the three for your display tank.

Since the second fixture list 12,000K Whites I would look at getting those in the fixture. for your whites rather than the 18,000K. For 48 LED's I would go with

4 380 nm
14 Royal Blues (aprox 455 nm)
14 Blues (aprox 470 nm)
16 12,000K Whites

Remember color selection is something very personal. My DIY's are roughly 7 Royal Blues 7 Blues and 4 Neutral 4,300K Whites. I have been told by different people it is too blue and by other it is is too white. As you go with a higher color temp of White you need more whites as they become bluer.

SaltyJim · 05/22/2012, 10:29 AM

I just got my A4 unit yesterday, will post pics later if no one else has.

There *is* a heatsink, and the weight of the unit was surprisingly heavy. Heavy enough I have to change my hanging system from what I had for my Geissman 250 fixture.

My one complaint, the fans are on all the time when the dimmers are turned off. Not really a problem if using timers, but could be an issue for trying to use a controller. For anyone that has not yet ordered from Sam, ask him if they could put the fans on a separate power switch.

AcroBluz · 05/22/2012, 11:58 AM

Thanks for the input. I will email them to clarify but I will probably order the 2 for my frag tank and see how they look as you suggest.

Shells4 · 05/22/2012, 02:01 PM

I've been tagging along on this thread for awhile now. Just ordered 3, dimable 55 LED 1:1 unit. Will post before and after pictures when they arrive. I actually had bought a unit that looked identical to this from my LFS. Very long story....they only had one so he ordered a second one for me. Took over a month and then they got the wrong light in and gave me a run around with the price (alot more) and would have to wait at least 30 more days for the replacement. I ended up returning them and ordering them myself. I really liked the one light I had purchased from the LFS, only played with them for a little bit but I was impressed. One of the LFS units was $250, on "sale" and I got 3 of the same lights for $480ish.

A ballast on my T5 went out a few weeks ago, so I have only been running one t5 light bulb for my softies and low light corals. How do I go about acclimating them to the new lights? I was assuming I should dial them down to the lowest setting, start with the white lights on an hour or so a day and bump them up an hour a week. How long do you wait to bump up the intensity? Is it okay to run the blues on low for several hours a day? I don't want to fry the corals I have!
