Chinese LED Lights

2:1 of cool whites to blue... maybe. Any addition of neutral or warm whites needs at least 3:1 or even 4:1 for 20k at 100%. The whites from EG are extremely bright. 17 out of 55 leds in my IT2040 are a mix of neutral and warm white, and at 100% it is a 10-12k look.

Bhazard451 sorry for spamming you. I didnt understand if you ment that the IT 2040 from evergrow had resistive dimming? Thank you.
 
Im running both my channels on the d120 on 100% and they are 2 inches above the surface of my RSM130d. Have it this way since one week back and my corals are doing great :)

+1, absolutely. the whites are REALLY bright. they wash out the blue easily so 2:1 CW:RB is not going to cut it for a 18-20k look. i have a little over 3:1 and it still doesn't do it. i'm ordering a few more through another GB to pick up the apex-dimmable units and am doing close to 4:1 for a 20k look and getting rid of the green, spacing out my reds (660nm) for more coverage and adding two "UV" (400nm).


you might be able to do that but my PAR would be too high with the blues at 100% and with the disparity in correct reading by the PAR meter, it gets even trickier.

i've only heard of one person with the d120s running one of his channels at 100%. they are well designed and put out a significant amount of light and PAR so at 100% you better have the depth and coral placement that requires them or the time with the light to gradually get your corals happy with that kind of intensity slowly shaping them to their new intense lighting.

Well, I'm basing my post on an old D120 that is 3:2 blue to white and I have no idea which whites or blues. It only runs at 100% and it looks very 14K.
 
I will try to post this in this thread.

I have my d120s mounted at 7.5" above the water. I am coming from 4-55watt t-5's and 2 vho's. The light is brighter, but seems to have less of it. The fixtures have 90 degree optics. All the light seems to be beaming straight down. The center brace on my tank is creating alot more of a shadow than before. Any input from anyone running this same set up. I can adjust the height fairly easy. Does it make that much difference to have the fixtures closer to the water? Should I remove some of the optics closer to the center to give a better light spread?

I have had them up for an hour now, and my corals do not seem to be responding to the light. Will they need time to adjust to the new light? I have them at about 45% now.

You say the light is 'brighter', but you have 'lessof it'. I guess I have a bit of a problem understanding those 2 statements. Do you mean less in that it doesn't spread enough?

The questions I have for you are, how many D120's do you have up and over a tank that is how big and how deep? If you are getting too little light spread, rather than taking lenses off the center leds, I say take them off the outside rows where you want the light to spread. At 7"-8" above the water, I wouldn't go any higher unless your tank is shallow.
 
Considering 120D, How much of each channel should be run for a red sea max 130d?

Your tank is just over 31" deep, so if you have 90 degree lenses, I'd say you may end up at or near 100% if you are doing sps. If you have 60 degree lenses, and given the lenght and width of your tank they may well work for you, it would probably be low (maybe 70-90%). The best thing to do is find somebody with a PAR meter and get some reading at various power settings at both the top of your rocks and the bottom of the tank

Thank you! I was worried my soft corals probably don't like full output

Red Sea Max 130D is only 24" deep, maybe less. I just upgraded from it to a 125 gallon. 90 degree optics work best on it.

As far as resistance dimming, it means no controller PWM or 0-10v Analog will dim those drivers other than the one included with the IT2040.

The light is brighter, but the spread is less. Is the coverage significant in spread by removing the optics? My tank is 4' wide and 21" deep. I keep lps, a few polys, a few rics, and 1 anemone. I eventually want some sps. I have one birdsnest frag as a test sps fir my tank. I can lower the fixture easily. I dialed the lights back to 35%. I am monitoring closely for bleaching my corals. How far off the water surface would you recommend to put the lights. I have 2 over the tank
 
Grayhead I just set my lights up Tuesday. Same layout as monkiboy. 2 D120's with 90 degree optics on a standard 90 gal 4'x18"x24". I have mine 13" above the water too get the spread I wanted. I have the blues at 30% and whites a little less than that for now. My lps near the SB were not liking them dialed up any higher. Ill dial them up gradually. Try raising them a little and see how the look. BTW these lights are great. I'm glad I stumbled onto this thread and the old thread as well. A lot of helpful knowledge.
 
I copied the same layout. Seems like a good mix in colors. I made my support to be able to adjust the height. I have a shelf above my tank that was originally built to hold a quarantine and refugium. My tank is an in wall. I can go up maybe 2 more inches. I would then worry about the fans being restricted by the shelf. I did a temporary setup to hold my lights. I used 4 eye bolyz like would go to a door latch. I then used pull chain from the ceiling fan section in lowes to hang the lights on. Very simple to adjust.

I like the lights so far. As the night went on, the corals seemed to respond well to the lights. I just dont like the shadow going thru the middle of my tank. Hopefully someone will come up with a mod to this light to make it dimmable by a controller.

bhazard, I was wrong about the depth on the tank. I was reading the cabinet specs. My bad. Here are the dimentions:
"¢Total system volume: 130 liter/34 gallons (29 gallons aquarium volume, 5 gallon filter volume)
"¢Length 24" X Width 19.7" X Height 19.7"
 
Kurt,

When I started the process of buying leds for my 6' long 180g mixed reef, I was going to get 4 D120's. But after seeing the IT2080 I changed my mind. The 2 primary things that sold me (and there were way more than 2) were going from 8 power cords to only 2 power cords. And having the auto on/off timmer dimmer. At our group prices, 4 of the D120's would have cost $560 delivered, and 2 of the IT2080 cost $660 delivered. For a hundred bucks more it seemed like a great deal. BTW 4 of the IT2040's would have cost $960, at that price I'd have gone without the controllers. 2 of them at $100 is OK, 4 controlers at $400 over the D120 cost is out of line in my opinion.

how tall is your 180? My concern is that my tank is 30" tall I want to make sure two IT2080's is enough for a sps dominant 30" tall tank?
 
OK I am going to try here as I had no luck with a reply in the main equipment section so I will try here. I cannot believe no one has and heard or has experience with this company and its products.

OK, I admit I haven't read all LED Light threads on RC, but I did try a search for this company's name with no results. Tried to use quote marks around the name and all I got was references to "reef". I apologize in advance if this company/ light was been discussed as I cannot imagine it has not.

O. C. Reef of Dana Point, California [Orange County] has a website that shows several models of lights. They are apparently a LFS that imports sub assemblies from China. They claim their lights are assembled in the US. Their Tesla line has some good features [CREE LEDs, programable, full spectrum]
and prices/ warranties seem decent. The website seems to be a little disorganized but their products seem to have potential.
This is a link to the light I am interested in.

Anybody have any experience with this product or company?

bhaz, when you took your par measurements what percentage were you on and at what height above your tank did you have the fixture? also how deep is your tank
