Evergrow Lights?

[CBART]

Just wondering if anyone has had experience with these lights, and what you think of them?

Are these Led for Reef Tank?

I may order one to my Detroit address let me know if your getting one

I was just wondering if there was some personal experience on the forum. Wondering if the colour and growth is comparable to T5's. If they work for softies to SPS or just softies and LPS. Are they just a display light with nice colours or also good for grow out? I understand there is write ups on the internet, but it's nice to hear peoples personal experiences that don't have an agenda.

Evergrow D120 is cheapish, works well. I think its fine for growing lps zoas at recommended #. May need to add more lights for sps.

It doesnt give the best color rendition for corals. I think that goes for every type of light bulb types. Cheapest T5 bulbs and MH bulbs dont have good color rendition either.

They are a great light for Fresh Water planted tanks but I wouldn't waste your money putting them on a reef tank.

I thought Brandon ran these exact lights over his lps bow front with good luck?

Hey you know you get what you pay for, I guess they're cheap enough, could give them a try

First off, there are several types of evergrow LEDs. My comment was for D120 only - I have that one. Other Evergrow LEDs have better colours.

D120 is what made evergrow lights popular. They are incredibly reliable - thousands upon thousands have been sold and used and I haven't heard of too many complaints. In some ways, this is the model T of LED lights. They made LED reef lights accessible to everyone, made cheaply and reliably.
The design has been copied by other chinese LED makers successfully. They are very bright at 100% for both channels. They will cover 24"x16" well I'd say. If your tank is more than 24" I'd get 2. there are par measures on other forums. Flourescent colours in corals are induced by the blue spectrum as my understanding is.

For best flourescent colours you do want a greater range of blue LEDs - that cover from 400 to 470nm. Near 400nm they are often called "UV" but it isn't true UV and it won't cause you any harm at 400nm. Another one is called "Royal Blue" which is in the 450nm area. Then there is the plain "Blue" which is in the 470nm area. The plain "blue" led chips are the cheapest, and D120 has a lot of those in there, and only 7 royal blue, and 4 UV. So it gives very good flourescent colour, but not the best colour. So you have to look at what each LED fixture has in terms of types of LEDs.

If you look at Evergrow's programmable fixtures, like IT2040, etc. those have considerably more of the "royal blue" in them then the plain "blue". Those I believe would put out better colour rendition. For a bit more money you can better colours AND programmability to boot.

That said, I did see a LOT of folks at the Fragfest using the D120 and their clones to light their displays, including Reef Hero and their corals including SPS looked AWESOME. So the D120 will surprise you with what it can do.

And final plug for Evergrow. From what I can see evergrow is a ton more reliable than some of the more expensive upmarket brands which have had incidents of parts or boards burning on them just outside the warranty period.

ReefSupplies has all the variants of Evergrow as do a few local stores. There are reliable D120 clones on ebay that are cheaper and just as well made. Mars is a brand that comes to my mind immediately. I hope that helps?

Running the IT2060's from reef supplies.ca since November. Free shipping, warranty honoured in Canada.
Very happy so far replaced metal halide.
Great colour, growth rates not the same but the svaings on hydro has been HUUUGE!
and run cooler. Im happy so far.

yeah lots of advantages. I think you can get better growth rates by increasing the number of units you have on them. If you have a 4 foot long tank (conventional 75, 90 or 100 gallons) instead of two I'd get three. That would increase par values, match those from MH, and would result in better growth IMO. the third one doesn't even have to be an IT20XX which are $300+. I think a simple D120 clone which costs $100 can be used with a cheap Canadian Tire timer to augment the other two would give the results you're looking for. And that's the cost of a good MH bulb isn't it. Can't beat that!

My 90 gal under 2x 165w Chinese leds (ocean revive) don't let anyone tell you they don't work, are junk, can't grow coral... Believe the proof is in the picture..

very nice tank. I have the d120 on my fowlr tank, I do have a few pieces in there and they are doing great, wonderful colour and awesome growth..I think they are great lights too..

 

[Jewel]

Fowlr That's great, But there no way in hell you'll get the same results as MH, Take a picture of your tank today and in 3 months and if it's comparable I'll eat my words.

 

[Bfofre]

That's 18 mnths..start eating

 

[Bfofre]

Oh.. And furthermore.. I don't dose, monthly water changes.. And very little fuss with my tank.. My first saltwater tank 18yrs ago.. I'm a believer.. You don't have to be

 

[Bayinaung]

That's a nice looking tank you got thereBfofre. And the corals look fantastic.

Thanh, you are using ALL LEDs for your SPS tank aren't you?
