chinese led lights

[cmantis]

Why green? Everything I have read says it doesn't add anything. Red is mostly for pop on certain colors but can overshadow other colors and is included in white spectrum.

[jroescher]

Does anyone know if there is a minimum or maximum number of LED's that can be controlled by a dimmer? Or switch?

[Chicago]

Cmantis. It will depend on the white. Neutral. Cool. Warm.

Ok now I need some help deciding what combo to get...

How does this look? I used the following criteria:
- 2:1 b/w
--- 2:1 rb/b
--- 2:1 cw/nw
- ~10% violet/uv
- ~10% cyan/red

2 uv
2 violet
2 turquoise
2 red
2 cyan
10 cw
5 nw
20 rb
10 b

Turquoise and Cyan are the same color/led. Otherwise, that's a pretty nice ratio. We need more pics of people's different ratios, as its hard to know what it will look like before seeing it.

Sup Rc,

I was wondering if this is a good idea or not. I have a 120 gals RR with 2x120w 14k Evolution led lights. I think i need a little more light for the back and the front. I was going to add a set of t5 retro for the front and the back, using wave point bulbs "reef wave" or should i get another 120w 14k led instead?

Here is how my led is hung inside the canopy.

[newe70]

After reading and debating on this fixture from this very forum for the 4 plus weeks. I finally pulled a trigger this afternoon for two D120 units with customized ratios with Sam from Evergrow. Now, I will have to make a hanging fixtures and try to figure what to do with my 48" Aquaticlife T5 fixtures.

I want to thanks Travis, Ihigh, bhazard451, and others for providing a great informations and feedbacks for these affordable fixtures. Just hope that my coral will be happier and this led fixture will last a couple years

I will post pictures when I receive them or after I set them up

[Chicago]

hey .. can you post the link sam gave you

Please look a little more into who your buying from.
"LED angle: 90degree
Optical LEN: NO"

Seems Odd that they dont know the product.

[ghrorick]

Hey Chicago, did you ask sam about leaving the optics off the reds and greens? I talked to Hendy about it and sounds like it won't be a problem. I just am not sure how much it will help

I requested for the 90 degrees LED Angle and no Optical Lens.

Can you elaborate more "Seem odd that they dont know the product"?

I am looking for something for my 125gal. What do you suggest? How many would I need for a 6ft tank?

[bskiba]

6 ft tank would be better with 3. and since it isn't super wide i would recomend 90 degree optics.

A bit more detail on your concern would be helpful instead of a vague statement like that. They've been very helpful for just about everyone so far.

English also isn't their first language, so you gotta give them some leeway. It's definitely better than my Chinese.

Ive got 3 of the 120s on a 220, good coverage, and its 7 foot so three would work on a 125

[ghrorick]

Bhazard what do you think about leaving the optics off of the reds and greens? would that help with spotting? Or would I be better off with optics on all the leds?

[hockey00]

I purchased two nova a4 for a 4 foot long 75 gallon. I have 90 degree optics. I like the lights but I wish the coverage was better. Is there anyway to take optics out so they are 120 degree? I have them 8 inches off the water. I could modify my canopy to raise them up a few more inches. Any help thanks

[OrrG]

So would be correct in saying that the D120 or a Nova A6 will be twice as bright as an Aqua Illuminations fixture? These fixtures seem almost too good to be true.

I have a 200 DD 48" x 36" x 27". I'm looking to replace my 2 metal halides - 250 W radiums, in lumanmax elites on a galaxy select a watt. I'm still going to run my 48" T5's, 2 ATI blue plus on an icecap 430 which are 3 inches off the front and back of the tank. These alone are great for dawn/dusk, light up the whole tank. I love the look of my tank with the radiums and blue pluses but figure I can recreate this look with the right leds and controling the blues and whites.

I thought about going the Vega route but I keep thinking, is 20 leds per fixture really going to be enough to light my tank? I mean the D120 has 55 and the A6 has 72! Seems like it will blow away a vega and day. I was really drawn to all the customization of the aqua illumination but I'm probably not even going to notice the dimming and ramping up due to the T5s I will be running which are on from 1200 to 2230.

So what are the main differences between the D120 and A6 and which will provide the best coverage/spread? I'm not keeping sps but do have 7 large rbta and a few clams on the sand, the rest are softies,lps, zoas.

[Chicago]

Here is link. What o you think. Red green and couple of blues on one dimmer


http://www.aliexpress.com/store/prod...587678783.html

90 degree or 60 degree optics if 20 inches above 31 deep tank

[Chicago]

By the way. Sam said not good idea o leave optics off and on others.

[daninfamous]

I got a taotronics (basically a d120) over my tank, my corals seem to be loving it, I think the colors are great, Mine is basic 30Blue 25White, color is a lot nicer than my 2 10k 2 atinic t5 combo.

If you open up the light, the optics are being held in place by a plastic shield with 5 screws in it. Unscrew the shield and all the optics will come right off. They aren't glued, but are being held in place by the shield. Smart design, as you can change/remove optics at will.

[Chicago]

Danifamous. Can you post pics. What percent are you running the whites at. .

It takes about 2 asian bridgelux leds to equal 1 Cree in output. They won't be twice as bright as an AI... but a little bit brighter, yes. The A6 would definitely be brighter.

The AI Vegas are going to have a ton of features and color customization ability, but you have to spend a fortune to light up a bigger tank with them.

Optics penetrate deeper and provide stronger light in a more focused area. No optics is spread out more, but not as strong. If the lights are in a canopy, you don't really need optics as much.

Either light would work well. You just have to decide which one you like better. I personally prefer the Nova with optics compared to the d120 with no optics over my tank. It just looks so much brighter, and more focused. If a d120 with optics looks like how the Nova does, its a killer deal for the price. Not having to buy 2 250w bulbs a year almost pays for 1 d120 itself... nevermind the electricity bill, and not having as much heat in the tank from the halides.

You could basically buy 2-3 d120's with optics for the cost of 1 AI Vega, and cover your tank completely. You just lose all the bells and whistles the Vega has. Are 3-4 Vega's and their extra features worth the extra $1,000 to you? If not, these perform similar at 1/4 of the price... which is why I love these lights. Using T5's with them would be an even better combo.

The other great part... no one has reported getting a bad light yet (knock on wood). They're made surprisingly well. I know because I've torn mine completely apart a few times now and took pictures Some of us have even soldered in different bridgelux leds, which isn't too difficult. I even added in 0-10v VDM light dimming for my Apex, which worked pretty well with the right drivers. Best LED value in the market outside of a DIY fixture by far right now.
