Chinese LED Lights

[Travis1787]

Yea I have 120 degree leds no optics ... its in a canopy and its covers my 36" tank but I'm soon gonna upgrade to a 60" tank and need 2 lights to cover that tank .... I know 2 of the style light I have now would cover it fi e but I wanna use 90 degree this time with optics and worry if they will cover the tank

For my frag tank( half of it) i am now running a mixed color LED and will post results in the future

Those VHOs fill in the missing spectrum that cool white/royal blue fixtures cannot provide. Without them, your coral would lose color within a few months, and may not grow as quickly. I've have seen it firsthand, as my first fixture was blue/white only, and it explains why so many AI Sol blue owners switched back to halides.

That does make sense, IME i never ran my halides without the VHO's either...i would never run anything without them..

I am currently running just a blue/white fixture and will see how that goes in the next couple of months on a portion of my frag tank..

The Reefbreeders layout is good, although I prefer mixing in neutral and warm whites in along with cool whites.

do you feel that the nova unit is worth the $100 dollar price increase? i could afford either, but im trying to see if it is worth it?

also, which unit did you find easier to work on? thanks again.

bhazard,???? thanks.

The easiest way to tell, is to look at acans that are normally red, or SPS' with a lot of color. They will change from red to orange, dull, or brown out over time.

so i was thinking about the T2040 does anyone have them? is it any good? I currently run 3 400 watts mh 20k over my 84" x 24" x 24" mixed reef would these be good enough? and do you think 4 units would be enough? thanks your in put would be most helpful!

[tomgndallas]

anyone experiencing quality issues from Twilight lately?

[jfeva0049]

Bhazard, how does this ratio sound for the nova A6

Dimmer 1= 24 led's
12 White 6500k
4 White 12k
4 White 16k

Dimmer 2= 48 led's

24 Royal Blue
9 Blue
6 Violet
3 Red
3 Orange
3 Green

what do you think???

I am running two of their units over my tank now and have had no issues.

I have 4 of the It2040 lights. My clocks have to be reset every day. Is there a fix for this?

Just spoke to Brian at Gehl and they are now filling orders for the LCD controllable/dimmable lights that are the same as the IT2040's, less one fan and the moonlights. They said they have a model coming out with the moonlights, which I couldn't imagine there being much of a price difference.

Has anyone used the 300w fixture with just white and blue leds. Would it work with just two on a 220g 72x24x30? Are they to much lighting in one spot? Any thoughts would be great thanks.

I would either try and switch out some leds to put in other colors or do t5's or other fixture to get full spectrum.

Just finished modifying my Nova A4. I got itr with 20 royal blue and 4 violet on dimmer 1, and 16 white, 4 UV and 4 Royal blue on dimmer2. This was just too blue for my taste. I like a very crisp color. I dont like whites to look blue. I also do not like to use the dimmers for color adjustments, so I wanted to get the color as close to where I liked it at 100% both channels. I have been slowly adding and taking away certain colors and I have finally hit exactly how i like it. The final LED layout is 20 royal blue and 4 violet on dimmer 1. 12 Neutral white, 4 warm white, 4 UV, 2 red, 2 green on channel 2. Here are some pics. The colors in the pic are just slightly more white than real life. I am very happy with how they turned out.

That looks awesome cec!

The fixtures are good but the experience I just had from them wasn't good. I had to wait about a month to get mine and they just shipped them out today when they told me it was shipped this past Saturday.

No fix as far as I know. They would need to fix it. They told us when we were ordering those fixtures that the clocks aren't working properly and usually run 5-10 mins ahead at the end of the day so they had to order new lcd screens and fix them. They fixed ours before shipping it out so hopefully we won't have that problem. Try contacting them about it, they should fix it.

Is there a reason that anyone has not added in any of the yellow 600nm in their fixtures?

cec09 - that picture and lighting combo looks awesome! Do you care to share what exact bulbs you used "The final LED layout is 20 royal blue and 4 violet on dimmer 1. 12 Neutral white, 4 warm white, 4 UV, 2 red, 2 green on channel 2"

Since evergrow has so many bulbs to choose from I'd love to know which ones you ordered or what you put on your sheet to order. I ask because this is the bulb selection that was provided to us for our club buy and they don't really match what they send out on the excel sheets to order:
400nm
420nm
440nm
450nm
460nm
520nm
600nm
630nm
660nm
730nm

2700—3500K
4500—5000K
5000—5500K
5500—6000k
6000—7000k
6000—8000K
8000—10000K
10000—14000K

590-600nm yellow is so close to a warm white that it may not be needed if you use some warm whites. I'll be testing it in my next diy fixture, which is going to be one amazing light for my 120 gallon. The tank gets converted from fresh to salt this weekend.

What is the max K Whites that YOU personally use in your fixtures. There is such a wide K range in the Bridgelux LEDS that EG is using in these D120's is hard to choose.

As far as the 590-600nm (yellow)- I like the way the new Radion's look using them surrounded by other colors with just the Cool Whites.

I just ordered from them, so we will see, and I just received an email r/t info on the rated lumens per watt on there white LEDs and she (tracy) sent a form with the output ratings of the different leds that they use. With the white leds at 110lms/w, which seems to me normal. Although they can really claim whatever, but I should be seeing it over my tank in a couple days.

It has taken a while. 8 bus. Days for production, then 6 days for shipping. Seems like a month.

But will check quality.

Hi guys !

First let me introduce myself : my name is Julien, i'm and I'm from France.


I want to upgrade the light of my tank, it's a 24 gallon cubic reef.

I'm very interested by this chinese D120 LED light with custom layout.

I'm searching for a 14k-16k spectrum, with red to pop corals color.

What do you think about this layout :


Thanks guys !

120 watts , 90 watts, 300 watts, wouldnt really matter in terms of coverage, that woul d just be in intensity..with 72" width you can get away with three minimum but i prefer 5..three looks good but 5 looks ALOT better( less shading, brighter etc.)

The neutrals I used were bridgelux 8000-10000k. The warm whites were bridgelux 2700-3500k, royal blues were 440nm, violets 420nm, UV 400-405nm. The reds and greens were bought off of ebay and are also bridgelux. I did not use any yellows because i used the warm whites. They are very yellow. When I ordered my light there werent all these different options available. There was no sheet. I just told him how many blues, whites and violet and UV I wanted. He was not even using the reds and greens yet. I had the option between 8000-10000k or 10000-14000k for my whites. I chose the warmer because I like the tank more white with just enough blue to make the colors pop but not turn the water to windex.
