chinese led lights

Bhazzard. Would your mod work on an a6? I assume so. I like your comment on dimming by pot. Turning the knob on a pot might be easier.

I wouldn't think so. You'd need a different driver since each is now running 36 LEDs, not 24.

Get the driver sorted out, then yeah it should?

I see they now have red and green http://www.aliexpress.com/store/prod...586828063.html I like the middle of the page tells you how many fixtures you need for certain size tanks. 4 a6s for a 72 inch tank seems like alot considering you only need 1 for a 36 inch tank. I have 2 on a 4ft 120gal, can't imagine 4 on a 6 ft tank unless it is 30 inches wide

Just noticed it too. Seems like a good ratio. They also have the fixtures with optics right next to it.

Yeah think I am going to order 3 with optics, I have lots of red and green zoas and think the lights will help them show up even better

I'm in NY.

The combo with red/green seems to be the nicest so far. It would look just like the fixture I have over my tank now.

Once I finish retrofitting the Nova with Crees and Luxeons, I'll probably sell the temp d120 I have over my tank.

Here is a list of DIY combos I have found:


Shenzhen Sanxinbao Semiconductor Lighting Co:

4) 24 blue + 4 uv and 27 white

5) 26 blue + 4 violet and 21 white + 4 uv (with 90 degree optical lens)

6) 28 blue and 14 white + 9 blue + 2 uv + 2 violet

7) 24 blue + 4 violet and 27 white

Everyone has a different preference. Did you ever use MH or T5? What bulbs were your favorite? This would help in choosing the led ratio.

I like the added color pop of 2 red/green/cyan, but it isn't needed. Multiple colors of white (like cool white, warm white, neutral white) are a much better option.

Sounds good. I will definitely add some red/green and vary the whites. Thx for the help!

Has any of you experienced brown algae on the sand with chinese led lights?

[Chicago]

bhazzard.. im puling the trigger on one unit.. the a6. to see how it works out.. what to do you think about this config.

24 white.. cool?
3 green
3 red
3 violet or do uv?

36 royal blue

optics 90 degree.

you mentioned spotting.. think i can do the red greens in 120 optics.. or would that be expecting to much from sam to do two different optics?


thanks

My tank is new, so it has a little bit of it anyway. I can't tell just yet.

Violet 420nm. Nova has to use optics by design, it cant do 120 (no optics). Seems like a good ratio to me.

I need some advise on what kind and how many LED fixtures I need for my tank. My tank is 72"l x 30"w x 22"h. Many SPS with some LPS. Currently using a Photon with 4 x 250w MH and 12 x 36" T5.

I am looking at the Nova A6 and the 55 x 3w square fixtures (http://www.alibaba.com/product-gs/58...ium_Light.html).

Which of these fixtures would you recommend and how many do you think I will need?

3 of either would work. The Novas would be more powerful, the d120s would be cheaper. You can also link the 3 Novas together so that they only use 2 wall plugs instead of 6, which is a nice touch.

[Dobbs1101]

So, do you think this light would be close to 20k 250w MH radion bulbs? do you think there are too many red & green? http://www.aliexpress.com/store/prod...586828063.html I'm trying to get a 20k look but not all blue but with some bright white. I don't want it too dark.

[Chicago]

i have sam doing a link with the above d120 with the red green and violet.. he is adding the optics of 90 degrees to it.. will post when i get the link

Thanks bhazard451. From what I have read on this thread, the d120's lack optics which require them to be placed close to the water surface, but I like the addition of violet, red and green. I was thinking of 4 of them arranged width-wise across the tank. I see that someone is looking at get optics for these units and would be interested in that.

The Nova 6's look nice, but I don't see a mix of violet, green and red. Can one get these added and what configuration would you suggest? Ideally I'd like each pod of LED's to have a consistent mix of colors that I could dim to achieve an overall color I was happy with. Three Nova 6's arranged length-wise look similar in price to 4 d120's arranged width-wise.

Also, I'd like to be able to ram up the lighting. Right now I turn on my actinic T5's, then duo and fuji T5's and finally my MH's all controlled by my Aquacontroller 3.

Your input is much appreciated. I am very happy with my coral growth and am approaching the switch to LED's with a lot of trepidation. I don't want to damage my SPS and undo years of pain-staking efforts.

You can get optics for the d120s. They cost a little bit more, but are worth it. You can also request red/green for the Novas too if you want them. I love the customization ability for these.

What you can't do is use your Aquacontroller to dim the lights. These lights are not made to do it. It requires extensive modification and different led drivers.

tell us a little more about spread for green red and violet.. is there a way to make those more diffuse.. i think some one mentioned they tend to spot?

[ghrorick]

I am looking at the same lights. I am half tempted to see if they will leave the optics off of the red and greens which might help a little with the spotlighting.

[Chicago]

thats a thought.. i can ask sam to leave off on the red and greens.. and on the violets?

Can you post Sam's reply? I'd be interested in the same, ie. leaving the optics off of the reds and greens. What optics are you looking at?

[Chicago]

looking at 90 degrees.
