Reefbreeders/(Evergrow OEM) Fixtures D120/IT20** series

Dimmer for whites...

Dimmer for whites...

Hey guys,

Been reading and learning as much as i can in the last few weeks - just set up a new 90 gallon reef to be. It's been a great place to learn so far, so thanks to all you experts for sharing the knowledge.

Anyway, purchased an IT2080 from OR and had a question. When I hear sunset and sunrise lighting cycles I was thinking this would allow the fixture to go from off to very little light and ramp up to "full sun". On the fixture I received today, the white channel (2) is pretty bright even at level 1. The blues, which granted, is only 3 leds on the lowest setting, seems like they're much dimmer. The scale on the white seems like it goes from 100% to about 50% in reality rather than 100%-1%. The scale is obviously somewhat subjective, but I wanted to get someone else's experience - Do i maybe have a bad controller or is this normal?

Thanks!!

I have two photon32's (stock layout with 90 degree optics) over my 210gal and was wondering if someone could ballpark me some par numbers?

oh, and has anyone found their fish to be flightly/spooky under these led's when cranked up higher? It seems as I have raised my power levels my fish are quit skittish...

David, I have two EverGrow IT2080's over a 180g, so similar but not the same as yours. I run mine for an hour at 80% blue and 50% white and I get 200 PAR at 20" down. At 100% on both I get 225-240 PAR at 20". My lights hang about 6" off the water.

I have set my lights on 'sunny' (100% both channels) for short periods of time and my fish seem perfectly OK with it.

Sounds right to me. The white leds do look 'brighter' to our eyes when the power is equal (blues below 10% don't count as they are different). With the lenses that many leds have, the light is more intense. I have 2 of the OR-IT2080's over my 180g and I do an 8 hour sunrise, a 1 hour midday (80% blue and 50% white) and then an 8 hour sunset. The power percentages change by about 10% per hour and the first few hours of sunrise and the last 4 hours of sunset are blue channel only.

Most fixtures these days are 1:1 or 2:1 blue to white ratio and if you understand the way light works and what your corals need, you run the blues close to as high as you want without doing any damage and then run as little white as you can and still get the white look you want in the water. Adding more white above that point is only marginally helpful to the coral and does nothing for you if you were already as white as you wanted. I predict in the not too distant future, fixtures will be sold at the 2:1 and 3:1 ratio rather than the 1:1 and 2:1 ratios they are now.

I'm going to do a re-build of a dimmer fixture with 55 leds and only 4 or 6 of them will be white. There will, however, be more red and some green leds in a clump. The hope is, the red, green and surrounding blue leds will mix and look white to our eyes and brains. Your TV uses RGB (Red-Green-Blue) leds and many stage lighting setups are RGB as well. But the coral, and more importantly, their zooxanthellae, don't have our eyes or brains and they still 'see' red, green and blue (better for the coral than white leds which also add in yello and orange which corals don't need... but nuisance algae and cyano bacteria both use.

Has anybody tried to dissamble the IT2080? I want to paint it white - I dont care about the Waranty

Does it look to be easy to pull apart?

It's not hard to take apart and put back together. And as an EverGrow warranty provider, it doesn't void your warranty.

Just remember, the black is not paint, it's powder coat which is stronger, harder and stands up to salt water and heat much better than paint. Seriously consider scuffing the surface with fine sandpaper and then cleaning it well with a good cleaner that evaporates quickly and doesn't leave a residue. Then use a primer and then paint.

Awesome thanks.

So another 6" deeper I'm probably still at 150 par or so at my settings?

Cool, thanks so much for the info!

One more question - maybe OceanRevive could answer, if I want to remove some of the led lenses to increase their spread and coverage on the ends, does this void my warranty?

No it does NOT void the warranty on either the EverGrow or OceanRevive fixtures. We are an authorized distributor for EverGrow and warranty service center (in the US) for EverGrow as well.

And thanks for asking the question.
 
ok I am looking at buying led lighting, I like the programmable style so the economy is out for me,

here are my tank specs:

185 gallon acrylic

60 x 24 x 30 top to bottom

what lights should I get and being 30" deep what optics as well
 
I currently have a it2040 Im looking to get rid of cause Im upgrading tanks so it wont fit. I swapped some led's and found personally that the warm whites made the tank look kind of dull. Added a couple violets and a couple 20,000k and it made a huge difference.
 
Not quite sure if this has been answered due to me being kinda tired tonight and not wanting to read all 52 pages of this thread, but whats the difference between the reefbreeder economy fixtures and the ebay fixtures besides being 40-50 bucks cheaper than reefbreeders?
