Very soon. I'll be getting one of the first production ones and testing it, just like I did with the Nova.

This is what mine looks like with the warm, neutral, and cool whites, blues, and violets. I think I nailed it, but I might try adding some reds and seeing if it makes it look even better. The warm whites should provide enough red in theory without needing to do so.

I would love to see a FTS of this light. I am thinking this would be perfect for my 40B but I too am thinking of adding 2 reds and 2 greens. What do you think.

I have been searching for that perfect crisp color without it looking too pink or purplish. My leds would be sitting approx 6" above waterline enclosed in a canopy so I won't be needing optics. I plan on keeping a mixed reef with option to keep anything if I find something I really like. Any thoughts? I have been following this thread for Weeks but only see peoples gfid ideas but not top many tank shots.

Mlott i think i have managed to attach the layout. This is the layout that Twilight suggested i should use. I supplied them with a breakdon on the number and colour of leds and which channel. Twilight layed yhem out and asked for confirmation before procedding. I have had nothing but excellent customer service, Lyn was my contact and it is unfortunate that it has not been the same for everyone!

The photo of the lights is not the clearest, f2.8 does that to you. Unlike looking at the light directly the photo shows you the different blues.

I am very happy with the colour, spread and power, my tank is 26" deep and without a par meter i would say i am getting plenty of penetration. I am going to reduce the white channel back to a max of 65%.

bhazards getting this light soon. He is great about reviewing stuff. Im sure he will post a FTS when he gets it.
 
I got the default sunrise/sunset program for the new fixtures, but I can't attach the excel sheet with it while I'm away.

It basically shows the brightness changing at every hour. If that means every hour can be custom, it would have 24 time periods to set over 6 or so that some fixtures use.

I was following this thread religiously every day for a while but haven't kept up lately, going to keep my halides and T5s for another year at least, so I'm not sure if this has been covered or not.

What would be the best layout on a D120 for a refugium/macro algae planted tank? I'm upgrading my fuge to a 40 breeder and wanted to try out some of the different macro aglae. I'm thinking lots of 3500k and 6500k and some reds. Was going to go with a 36" T5 and some GE 6500k bulbs but figure this could be a better option.

Has anyone done a layout specifically for a refugium yet?
 
Evergrow sells grow lights for plants too. I'm not sure if it would work for macro algae however, haven't looked into them.

The new fixture is now shipping. I'll post pics and impressions as soon as I get it. I'll post a full review once I let it run for a day or two.

I cant find any places to borrow a PAR meter from, so I'm going to buy my own to test these with too. I'll be able to take measurements soon enough.

I'll also compare it to my Cree/Luxeon DIY. Its too bad I dismantled my Twilight fixture for parts, or I would have compared them.

Anyone try the new lower color temp leds mixed in yet? Any thoughts yet or people still sticking with 6500k and 15000k leds?

Most of LED grow lights are for growing Medical Plants/Tomatos/Vegetable, less people use for algae, you might be the first one.:smokin:

Keep in mind it is a pre-production sample. There could be a change or two in the final shipped unit when they are available.

The labor day 10% sales luckily have coincided with my need to purchase a PAR meter.

This is the default custom sunrise/sunset setting. If you can think of a better one, say so and they will use it.

I have a Taotronics (Chinese) 140w LED fixture over my 60 gallon cube. Supposedly this fixture was designed with ease of maintenance and customization in mind and it is supposed to be very easy to replace LEDs in the fixture.

I am considering making some changes and converting it to a more full-spectrum-like fixture. I would like some input/feedback from those of you who have built or customized full spectrum fixtures. This is what I have in mind... The layout may not be exactly like this, but pretty close.

They're still working it out. Since Reef Central members have bought quite a few fixtures from them, they're going to offer a promotional discount for Reef Central members for the first round of lights, which is very cool of them.

If they can do it, it will be a competitive price. I'm hoping for $250-$300.. but if they can get it lower that would rock too.

You have to know how they are wired and what drivers they use. If the driver is around 90volts, then 24 leds are wired in series each driver. You can replace the leds if thats the case.

If the drivers are 48v or so, they are wired in parallel, and you might not be able to swap colors because the forward voltage of the different color leds are different.

If you really want to go nuts, you can gut the whole fixture and replace the whole thing with Crees, Luxeons, and SemiLeds like I did.
