chinese led lights

[latinyoungn]

excellent pics bhazard!

I was wondering if anyone can point me to a thread or webpage that shows what each color temperature looks like? (ex: 12k looks like this: etc)

I like the Neutral and Warm Whites used. The only changes I would possibly make, are removing the cool whites, adding 2-3 reds, and maybe changing from 6 470nm blues to 4. 18k would probably need a few more RB than what I have.

Well I went through a lot of this Thread......so tell me where I can purchase (3) Evergrow IT2040 lights for my 180?

ok, crazy amount of info..

I have a taotronics now over one of my frag tanks, but was wanting a new dimmable one for my other frag tank. I like the 250w 14k phoenix se halide look i have over my last frag tank.

What d120 should i get?????? I know there are a bunch of slightly different options, but would love the TOP 2 or 3 to narrow it down..

Either through chat or contact now. The light isn't listed on their website yet.

In your mind, are the new lights worth the additional $110? The dimming lights are purely for aesthetics, correct?

Thanks; I've contacted them....my MH's are in need of a bulb change and have approval from the wife to pull the trigger on LED's!

One question; does the fixture controller have timers on it for dawn, full sun, dusk and moon? Thank you for your review it was VERY helpful

It is more than just automatic dimming that was added. The aluminum heatsink and adjustable hanging kit are worth ~$50 alone. The ability to plug one light into another, and power both through one cord is also a rare feature. An automatic sunrise/sunset controller usually costs $50-80 on top of that, and you usually need to do the wiring on those, or you would need an Apex. Moonlights are also a nice feature that add ~$20 to the cost of a build. The remote control is icing on the cake. I can change the light from across the room.

If you don't need or want those features. The leds are the same that would be used in the D120.

The custom mode has a full sunrise/sunset schedule pre-programmed, and you can edit the brightness every half hour. By default, the light will start at dawn, reach 100% for a few hours mid day, lower for dusk, kick in moonlights at night, and shut everything off after 1am-2am ish.

The only thing it doesn't do as of now is ramp up or down. It only changes the brightness when it reaches every half hour/hour.

Thanks again; looks like a perfect fixture for the money. I hope they contact me soon as the money is burning a hole in my pocket!

So in what increments does it dim?

In manual mode, it dims every 1-2 increments from 1 to 100. The white and blue channels shut off at 10, and the moonlight takes over from 10 to 0.

I haven't tried editing the custom mode yet, but i would assume you could edit each 1% increment.

That would seem to be pretty smooth.

[jefftse]

Can we get some par number?

Manually, yes. Sometimes though in sunrise/sunset for example the light is programmed to change in brightness by up to 20 between an hour... say from 40 to 60%. It is an abrupt jump in brightness, as it does not ramp up to it slowly. You would have to edit the time points to make it a bit smoother, which I am going to try later tonight.

PAR meter is coming Thursday or Friday.

While examining everything yesterday over my tank, I noticed something interesting with my coral. My Duncans have started growing 3 new heads that I did not see previously, and my sole healthy SPS stick has grown a bit. Everything seems slightly bigger, although it is hard to tell without growth pics. Leds can definitely grow coral, although I am not sure if it grows quicker or slower than MH/T5. Growth itself is all I care about.

My water parameters have been much better, and algae has gone down greatly despite using red leds and warm whites in my Cree fixture. As long as your water is low in nitrate and phosphates, you don't have to worry about algae using a few reds/warm whites.

Just bought 5 of the new units from Evergrow.. very excited.

I modded bhazards layout a bit to suit my tastes. I like a slightly warmer
look and put in 2 reds.



Should have them in about 3 weeks. I'll post my thoughts when I get them.

I might become a US reseller for Evergrow if I like the quality.
Those concerned about dealing with China will have a place to buy them from
in the USA, someone to call in the US with questions or issues and I take
CC's directly. I run another web business so this is an easy extension.
Hopefully the quality will be great.

Which ones are the cool white?

Does anyone have a clue as to what this "pink effect" is? I'm thinking it may just be a tint to the lens? If so, will it effect the wavelength at all? The specs do state 420-435nm which is what I want. All I'm concerned about is adding the spectrum for coral pigment rather than the what color my tank will look.

Any insight is greatly appreciated, thanks!

So no one can chime in on this? This thread was about Chinese LEDs, so I figured this was the best place to ask rather than start another thread.

I don't think anyone here have tried the pink led colors in their tanks. I know I have nothing to say about it. I'm interested to know also...

They look like standard Epistar 3W violets, but at 420-430. If it actually peaks at those wavelengths, it would be good to try.

The "pink effect" thing is just a buzz word for a Fiji Purple type color I'm guessing.

I have been watching this thread for a while, I wanted to use one of these lights as a test subject over my seahorse tank, and then if they work well, over my reef tank. My question is this....

While I like what your setup is Bhazard, I prefer the 18-20k look. Can you explain your layout a little better so that I can understand it. I am not sure what the 35k/65k lights are in your setup. When the layout is sent to Sam, do we need to use those numbers are is listing lights as CW/WW/NW acceptable. Also I would like some light in the violet ranges, perhaps 4 in the fixture to help make those floruescent corals pop.

Thank you ahead of time for the help.

when is this model going to hit the store bhazard451?
