Mars Aqua Chinese LED review (Ebay)

Starting up a new tank 48x24x16 with sps dominant, would 2x165w Mars Aqua be sufficient?

i would say long term, probably not. eventually the SPS coral will start to loose tissue underneath cause of shadowing. so either double up to try and avoid that happening or add a pair of T5s to help with shadowing....

to start off a SPS tank. 2 would be fine to get going....
 
Hi, this evening I fit 2x165w Roleadro (european seller of the same light) in a Aqua medic aquasunlight (my old hqi) for use the 4x54w t5 mounted in it. I think this is a good work :)

Another question or 2?

1. can I daisy chain a 300 watt to a 165, and that 165 to another?

2. I'm making my 300w and 2 165w Apex 0-10v capable. Can I daisy chain the blue channel of all 3 lights to one variable speed port (#3 on my Apex) and all 3 of the white channels to variable speed port (#4) of my Apex? Or do I need to get an extra VDM port?

Yes, just tie all 3 wires together and onto one wire of the apex cable, and so on. I did this for 2 300W units. All blues one channel, and all the others on another. Worked for me anyways.
 
Question that I know has multiple answers but I guess I am looking to draw conclusion on happy medium..so here we go... 40 gallon breeder tank mixed reef .. mars aqua 32" 300w .. about 10" above the water surface... can any you guys post what % do you guys have your full spectrum(white) and what % you guys have tour blues on as well as for how many hours each do you keep on thru out the day... I don't have PAR meter so I am trying to figure things out with out causing to much pain to the eco system and my tiny reef ...

Thank you

Hello All,
I wanted to provided the 165W LED layout that i made in case anyone was looking for it. Just like "rgulrich" 300W layout mine was put together using pictures and any information gathered online I'm also including how I'm planning to mod mine this coming weekend (providing the LED's finally get here from china). I hate how yellow the daylights are so Im replacing all (6) Warm White 3500K, and (4) Neutral White 7500K LED's with (4) 20000K, (4) 490nm, and (2) 395nm LED's as shown below:

if you all have any comments, questions, or concerns please let me know

I plan to mimic this setup, already ordered some leds on Ebay.
still good or would you adjust something?
I like blueish look so tank doesnt look washed out.
 
I have heard from multiple people now that a 300w can cover a 40breeder without shadows on the sides.

Can anyone confirm before I buy one, preferably if you have a picture?

the 300w damn near is the length of the tank lol...300w for a 40B is what i recommended every time

My Frag tank needed a upgrade for lights and I decided to give the Chinese Led lights on Ebay a shot. Im very impressed right now with them and for the money i don't think they can be beat. (I have no affiliation with these lights, im a hobbiest like everyone else.)

Black painted casing.

The LED Spectrum ratio can be changed for big order (more than 2pcs).





Ordered on Monday evening. Arrived Friday afternoon.





Packing was very good





Out of the box

















Mounted on my Frag tank. They did not give off a huge area of light, the frag tank is only 12" tall so i mounted them where they can hit everything in the tank. They are still a little high, Ill lower them later to let corals adjust.







All blue, and all White so you can see them side by side.





Randoms of the frag tank. These colors are VERY true to the real life colors. Im very happy with that.



















Overall im happy with these lights and would recommend them for a cheap alternative. I dont think they can be connected to any controller, so they are just a basic on and off with a dimmer.

I have had same lights for 7 months very happy with them
I purchased a bluefish controller and wired them up so have full control from app on phone even thunderstorms plus real time location weather simulation

This video caused a long debate on *********, basically, the take home message is that the $100 light can grow coral. Actually I have seen plenty of beautiful reef tanks including SPS dominated under various brands of black box led.
If you want a piece of nice furniture and controllability, and you have the spare change for it, go get the $800 light.

Well, I will take back the last sentence, if you want a nice piece of furniture and controllably, you can go with something like Reefbreeders, SB reef light, Led zeal, lumini Aqua, Everygrow (the same models as photon v2), Zetlight etc, plenty of choice out there.

Reefbreeders photon v2 or anything similar to photon V2, Zetlight and others lack spectrum blending. In fact a lot of those lights space diodes out too far creating huge disco light effects and spectral separation. If anyone has put any faith in BRS's spectral analysis, you'll understand that spectrum blending should be a concern. I looked at a lot of Zetlight fixtures and found them to be missing the 390-420nm range and doesn't quite hit all chlorophyll needs. I think this something that is better achieved with black box designs and shouldn't be entirely frowned upon.
 
Have you ever use a Radeon and a photon v2 side by side? If you have not, please try them in person and not just rely on what other people said.
I have both, I can tell you there is no visible disco ball effect on both.

I can also tell you that for almost two years of using both of them, the reefbreeders photon v2 has no difference in coral growth vs Radeon G3. Also, there are much less shading for SPS colonies from photon v2

I used to quite concern about spectrum blending and believed the cluster types of led such as AI hydra and Ecotech are the only way to blend spectrum. But in years of research and using various types of led in my coral lab, I found these results may help answer some questions:
1. If coral are position 5 to 6 inches below water surface, the water above the coral actually help blend the spectrum well.
2. White led are the full spectrum led, they contains the blue, red and green spectrum as the other color led chips. Other color is more like enhancements such as the blue and violet, as well as the so called "UV", which are at 400 to 420 nM.
3. If the almost useless green and red channels are reduced to low level or turn off, there is no visible disco ball effect.

4. Coral utilize a wide range light spectrum and their photosynthesis action curves are wider than plants on the land.
Also there is one thing coral do that plants can not, is to manipulate light spectrum and convert them to be useful for photosynthesis via their proteins.
So as long as white led is used, there should not be a concern of lack of some spectrum.

4. Coral growth in long term actually not much different among various led despite their design. But shading for SPS colonies, small or big, is very different between cluster types and grid type lay out.

Oh cool, copy and paste.

If the almost useless green and red channels

Let's at least research what we copy and paste.

Copy and paste? I type all these on my phone, lol
Copy from what?
