That was just one that I came up without red or green just for the hell of it. I made another one with reds included I can post later if you want to see. Like was said earlier this is all still trial and error. They are going to make some of my designs to see how they look. The ones with the controller will probably be out in a month or so.

So I have both of the D120 fixtures from Evergrow running for about 4 weeks now. Everything pop in colors and getting quite good growth on the SPS. For those who is skeptical about these LED light fixtures...these lights can growth SPS with no doubts...check out the results. The first pix when I used the Aquaticlife T5 4-lamps 48" with ATI bulbs. Other pictures are the LED fixtures.

here are my lights
http://www.aliexpress.com/store/pro...-and-15W-4Green-4Red-4B/317880_586828063.html
but with optics
I would say that there is a good chance of having anything get a little messed up when you change anything in your tank, lights or otherwise. Very delicate eco system contained in a small space. If I can give one RAVE review about my fixture and algae though (and this might or might not be because of the optics). The light is fairly directional and I centered it pretty well so unlike the old MH the glass gets zero direct light ie my glass gets next to zero algae growth. One less boring piece of maintenance
One week now and so far no visible algae what so ever, used to have to clean them twice a week.

Nice. Keep the pics and growth results coming.

CM, what post # were you referring to...3542?
Hey everyone,
Just wanted to thank everyone for all the info and work. I've tried to read as much of this thread as possible but it is just way too long!
Anyway I am posting because I am seriously considering purchasing 2 d120s from evergrow. I have come up with a few layouts for my fixture but I am still unsure of how i should handle the white leds. From all the reading i've done, it seems that people are making a shift to neutral whites from cool whites. I would like to incorporate both whites into my led unit but as many have pointed out, evergrow does not offer 4500k bulbs (nw). What mix does everyone recommend since they dont have them. I am concerned about the appearance of the tank, don't want it to be too blue, and the health of my corals. would a mix of ww and cw work?
the first design is what I would ideally like (at least i think I would!) and the second is with cw and ww. Any thoughts and/or critiques? thanks.

I'm getting some with neutral white and Sunny hasn't said anything about not having them. She just confirmed. Are you sure?

Their neutral whites are 6500k, and the warm whites are 3500k. Basic 14k look requires 2:1 or 3:2 royal blue to neutral white. Mixing cool/neutral/warm becomes a bit more complicated, but Maxspect uses a 2:1:1 royal blue to Cool white to warm white mix for their new 16000k r420r fixture.

Their standard cool white is around 10-12k.
Which one do you think would be equivalent to neutral white?
This is what they have listed as white LEDs:
Warm White, Pure White, Cool White(6500-7000K), Cool White(10000k-14000k)

Hello All,
A fascinating thread for sure. I was sure I was going to wait for the maxspect razor but the positive feedback and pricing is compelling for the D120 for sure. Found this specification interesting
http://www.aliexpress.com/store/pro...W-4UV-with-Optical-Lens/317880_590696994.html
Questions - Do you recommend any changes here for mixed reef about 30% sps
What type of whites are being used here CW, NW, WW? I did not see it in the spec.
Are the UV LED's something that is becoming more desirable ?
Thanks for the help, I am no expert in lighting and all the changes and developments are making it more confusing then ever.
Thanks Mark

CW 10-14k is being used unless specified otherwise.
UV Leds (under 420nm) are not desireable. Actinic leds (420nm) are.
You would be better off changing the uvs to 2 more violets, and 2 more royal blues.
The Maxspect R420r is no slouch for the money either. I am very interested in it when it starts getting reviewed. The d120s are the best value option by far though.

What is evergrow's standard blue led spectrum?

Their Royal Blue is around ~455nm.

Is royal blue their standard blue offered if not specified to them when a light is ordered?
I have to say after reading all these different color combo's and getting very confused, in the end The Evergrow 30b/25w I have currently have hanging/running on my 30g tank looks great. I can dial in any color combo i want. The 14k Phoenix was running is close to the same color I'm running now but the LEDS are much brighter. I have the blue at 50% and white at 40% and the growth and color is awesome. I don't know if I'll ever need to run the light at full power, but this is for a 17'' shallow tank.
What I'm saying is all the color combo's, red this, green that, etc... is almost irrelevant because you can dial in almost any color you want with the controller or knobs unless you plan on running at full power. JMO - but if UV, red and green do nothing for growth, for me, it's not worth sacrificing the extra bulbs.
I have been looking and reading for months now and the only thing I would do different is 34b / 17w / 4violet. The white on the Evergrow is really bright but 2:1 might be too blue. I added the violet for that reason and extra pop.
I think I'm going to get the following for the next 2 lights I purchase for my 120g http://www.aliexpress.com/store/pro...iolet-with-Optical-Lens/317880_593824789.html Still not 100% sure though.
I have given up on Twilight with controller, thanks to Bhazard. Controller would be nice but on my 120g I presently run 2- T5 actinic bulbs and 2- 250w MH and they are controlled with my Apex. no slow ramp up and all the SPS corals I have in my 120g look great and I get crazy growth. (2-T5 actinics on then 45min later MH1 comes on, 30min later mh2 comes on and the just opposite at night)
I may be wrong or way off base. please let me know, I'm learning just like the rest of us.
Just my 2Cents

I have a slight issue with your response in that you have never tried the red or green to see what benefit you will get from it. I don't believe I have seen anyone claim to have improved growth from adding just red or green, but rather improved color spectrum. And really, if you are only running your lights at 50%, what would it hurt to replace a few blues or whites with red / green / cyan / violet and maybe drive them at 55% power instead? You would gain a fuller spectrum and likely your reds would pop more, your green would pop more, and all your corals would florescence more with the addition of the violet. Just my 2 cents. No one is trying to confuse things, rather just provide our corals with the fullest most realistic spectrum possible. I aim to replace my t5's in which I run 5 different color bulbs myself and love my coloration and will be providing every color LED I can.
