Chinese LED Lights

[Saratj1]

anyone experiencing quality issues from Twilight lately?

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 !

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.

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.)

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
14000"”16000K
16000"”18000K
18000"”20000K

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.

Any way to mathematically calculate the "look" of a D120 bulb setup?

Any way to mathematically calculate the "look" of a D120 bulb setup?

Going for a 12k - 14k look. Any way to calculate the mix of nm and xxx k bulbs?

 

[jfeva0049]

whats a better layout of led's; inline like the d120 or cluster like the nova????

 

[mlott132]

You will not get good color mixing with the inline setup. I would recommend a grid style dimmer layout.

 

[skyrne_isk]

90 degree optics for sure. I have a few giganteas and SPS. I will link a pic when I get home of what I have. Most SPS are in the upper half of the tank for sure.

I am thinking about ordering one and seeing how it goes....since shipping both at once only saves around $20.

Not sure if the timers can be turned off, does anyone feel the sunrise/sunset dimming is anything to be excited about? I am not sure it does anything for the coral. Though to be fair, I still plan running my VHO actinics - sorry just not hip enough to give up the glow.

I ended up buying a different layout to cover my 60G 32 x 32 x 20. I went with a 40 x 3W unit, ran me around $400 with shipping around $100 of it from houyi lighting. Has a remote and LCD and has an integrated dimming module built in (which I find useless). I believe I am the first to go with these folks, will post my findings about the light as it gets along. I am putting it over the tank this weekend to replace a single 250W Phoenix 14K.

Here are the pics:

Well packed:

Canopy build:

Canopy finished:

In case anyone is curious, I am using a swing arm TV wall mount (rated at 60lbs) to secure the canopy to the wall - and allow me access to the tank when needed:

And for fun - anyone ever seen an Annularis smaller than a razor blade?

so is the d120 a grid style?

if so i was more curious between the d120 style and the nova style ??? is more better than the other? seems as if the d120 is the most popular style.

 

[Travis1787]

OK so I'm going for a? 20k look...... in the d120 now I have 30 rbs and 21 whites (10-12k) its not as much of a 20k look as I'd like I think it needs to be more of a 2:1 blue to white ratio ... on my next 2 I get for my 120 upgrade I'm gonna do that and add some reds and green and violets I think I'm gonna throw is a few WW ... here is the ratio I'm thinking about

32 rbs
11 NW (10-12k)
4 WW
4 violets
2 red
2 green

I'm a little over a 2:1 blue to white ratio but I think using 4 ww in place of 4 NW should even in out to what I'm looking for.... anyways here is the layout i made ... let me know if you think this will get me to a 20k look I want ... and also let me know if my layout looks evenly spread out enough .....

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.

Thank you for answering my question

Yikes....
Just got my new light from Reefbreeders...
Anyone know how I can mitigate this psychedellic multi-colorded disco ball effect?
Doesn't look natural...

with this pattern?...what degree optics?...was just thinking to order this unit! Is it that bad?

 

[TheReefKeeper]

Tagging along!

 

[psusocr]

I got a standard layout 120 from reefbreeders, the one for $199( $179 on sale now) and it looks really good on my frag tank, ill be monitoring color and growth over the next few months, but so far im happy with the colors..

i noticed no one is using cool whites a lot in the mix.. so is it better to simply use warm and neutral whites.. ?

Neutral and warm are closer to light the sun produces, and provide a wider spectrum than cool whites. I happen to think they look better visually too when combined with the right amount of blue.

while searching for the difference of the 3500, 6500, 12000k white leds I've ended up on this site www.americanaquariumproducts.com/aquarium_lighting.html and their information is updated (October 2012) so I think it's worth sharing this information to my fellow reefers.

 

[jfeva0049]

so is the d120 a grid style?

if so i was more curious between the d120 style (rows & column) and the nova style (cluster) ??? is one better than the other? seems as if the d120 is the most popular style.

anyone????
