O and bigcountry your tank is 6ft long mine would be 60" so 5ft ... I still doubt 2 would be enough for 60x18 tank size unless one unit will cover 30inches then it would be perfect lol

IMO, 2 would work, you would just have to raise them higher to get rid of the shadows, and put any high-light corals higher in the tank or centered under the fixture. 3 would allow you to put any coral, anywhere in the tank.

I have one of these fixtures over my 40 breeder and these are the sheeeezit. Everything but my rics are doing amazing! I would recommend these to anyone.

If these are quality LED lights 2 - 120 Watt units will be way more light than even a 400 watt MH bulb. With top of the line LED's your looking at 2 watts of MH's bing about equal to 1 watt of LED's. Now this is not true for all LED's but they would have to realy poorer quality than anything I have seen to be an equal match in comparison.

I looked at the tech specs.
The 20K unit uses 20,000K LED's and an equal number of Blue LED's.
With just the blues on alone you have a 20,00K effect and with the added Blues your probably getting extremly Blue. Makes me wonder if you would get enough green and red light, for the reflective colors to look good.
From experine I have some red birdsnest that under daylight (6,500K) LED's do not show there red only the blue white tips, But with Neutral White LED's there red pops. I would suspect the 20,000K LEDs would be worst on reflective reds than the 6,500K's.
The 14,000K units uses 14,000K LEDs and an equal number of Blues. When both the Blues and the 14,000K's are on you should get an effect close to 20,000K look. While I still do not like the 14,000K LED's I think you would be much happier with these compared to the 20,000K.
Bridglux does make a 4,500K and a 6,500K LED and I think either of these with a ratio of 1 white to 2 Blues would look much better.

The light fixture I have is a 14k and with both lights on, it's very close to that.
here is just the whites. As you can tell it's very yellow. So even though they are saying 14k whites they are off.
both lights on taken with my phone. A little bluer than actually because of the white balance on the phone.

No problems with the deference between red and orange either.
as you can see with the acans.
just a few more here.

Opinions on these lights?
Opinions on these lights?
i have a 180 gallon long and it has 2 center braces. i was think of using 3 of the aquariumled.com 14K units that have the 40 3W leds one in each of the three partitions on my tank
the tank is 72" x 24" x 24"
Should these be sufficient to grow sps or will i need additional lighting
I would like to spend about $500 in lighting and this will be just under that
Thanks

Yes they will support SPS. Since your at 24" deep though, you might want to get 4 lights, and hang them like this guy did, hang them 8" or so above the water and vertically facing instead of horizontal:
Acclimate slowly, start on the bottom and work your way up. Up top these lights are VERY strong.

X2 dropT is all over it. Avoid the 20k and go with the 14k on these boxes. Popping red is the bottleneck on these boxes, and the 20k will be too blue.

Four is what I really wanted but my tank is a marineland RR tank. There is two braces on the top which splits it into 3 even spaces. each opening is approx 21" wide I was just going to center one of each light in each opening
I guess i can order 3 and if it looks like i need more order another one later
Thanks

I just reviewed Bridgelux pages the actual manufacturer of the LED's. They do not make anything like a 14,000K or 20,000K LED. The highest K rated LED they list is a 6,500K Cool White, 5,000K Neutral White, 4,200K Neutral White, 2,600K Warm White. So the listing of the Fixture manucafturer is probably giving a combination number for both the whates and the blues. If they are using a ratio of 1 to 1 with 6,500K Whites it would total someplace around the 20,000K range. But I know that would not give you a lot of reflective reds or yellows. The florescent reds and yellows would pop but the reflective reds and yellow would turn to brownish tones.
With the 14,000K they are using a ratio of 1 to 1 again but I would bet they are using the 5,000K LED's. A 4,000K led alone will give you very natural looking reflective colors throughout the spectrum. Then with the addition of the Blues it will cause the florescent colors to pop.
I would definatly run with the 14,000K if I were using these lights. The price of roughly $150.00 for a 40 3 watt LED's is realy unbeatable. It would cost me over $200 to probably build something like this with Cree LED's, and close to $200 even with Bridgelux led's.
With the 5' tank I would initialy go with two of these units. Then evaluate the lighting yourself and determine if you want ot Brighter or Bluer. If you want it brighter add a third unit. if you want it Bluer you can add one or two 60" blue strips in the future, using 454 nm LED's to get closer into the near UV Range, than the 460 nm LED's provided.

how much do you think my tank would suffer if i got 2 now and put them on my 65 gallon tank in place of my 250 watt mh ? i think one would be enough but two might make the switchless hard on the corals maybe? its a 3ft long tank 2ft tall ...
Man I saw a black box without all the red tape....

Check it out... In plain English.... 40 Cree 3w bulbs running at 120w...

If the 120 W aquameds are the quality they claim they are then 1 of them sould be close to the equivelent to 1 250 Watt MH. However they are not publishing all the fine details on what is in them so it hard to judge exactly if this is true.
With either one or two you should be able to phase in the lights by initialy running just the Blue LED's dor a dawn to Dusk effect and then the full LED's at mid day. this should not cause a sudden light shock on your corals.
However running two of them if they are as effecient as a quality usin would be would be an extrem amount of light for a 65 Gallon tank. Basicly its like running 2 250 Watt Metal hides on that tank whioch could cause bleaching of most corals even after going through estrem aclumation process.
This is the hard part about these black boxes. If one of these usints are effecent you fould get 150 PAR at your substrate level, But if it not at full effeciency you may be lucky to get 100 PAR at the substrate from two of these units. and even if the PAR is high enough the question comes if the light spectrum is properly proportioned to give the corals the lifght they need, without puping excessive red, or insufficent red to cause the loss of reflective colors in the red and yellow spectrum.

I wanted to show the difference in one of my tanks after about 8 months with LEDs.
Before Leds:
About 8 months after installing LEDs:
There was a little rearranging, but not much. Over all the colors are so different. In the bottom left of the bottom picture, see the neon green yuma rock? It is there in the top picture too, just not neon.
Two days ago i installed some UV-B Led strips to see how it would affect the reds. The only changes so far is the blues. Tips of acros and monti rims are turning to a bright glowing aqua blue. At night after my lights go out anything neon green ( hammers, kryptonite candy canes, etc...) keep glowing. Yes, glow in the dark. Not super bright, but you can still see them flouresence.
Here is what my monti looks like now after about 10 months:
I have no doubt LEDS can grow coral. And make them beautiful. As stated before all my softies that were red and changed to orange, are still orange. Hoping the UV will help, we will see. Hard corals that were red seem to have no change, they are still red.
Man, that is some testimony there....Awesome. :thumbsup:
