Chinese LED Lights

[rad1687]

Also, what have people been doing with the power cords when hanging the d120's?

[mattman]

Been following this thread for a while...I have some IT2060s coming in from reefbreeders. I'll post pics after I get them installed. It's a 36x36x25 cube

[madmike]

I'm using IT2040 for almost 2 months now and it seems that during a power loss/outage the custom settings made using 30mins interval is still there but the problem is when the unit turns on when the power comes back it will automatically select the 1 hour interval in which the case I leave it on its default settings, so I need to manually go to menu and reselect the 0.5h settings that I have save.

my lights do the same when I unplugged them... worried me for a second until i realized that just switching back to the 0.5h setting restored them... an annoyance but def not a deal breaker...

Question for those that own the D120 (value LED from reef builders).....Do you recommend the 60 or 90 degree optics or will the default be sufficient? I am planning on picking up 3 units for my 180g tank. I currently have 2 "48 marineland fixtures with blue LED strips and I still do not like the look plus my coral growth (if any) is really slow.

pics for reference of the marineland LED which looks yellow

I had a Marineland led, I won it at MACNA in 2010... it was worth just what I paid for it... nothing.

3 D120s should be just enough over a 180g tank. I have 90 degree lenses on the IT2080s over my 180g tank and they work great. Not much light spilling out of the tank and real good PAR values. I'm taking the lenses off any led that isn't blue or white so the color can spread a bit more over the entire footprint of the light.

Thanks Ron for your quick reply! I'm placing my order now

My lights arrived today, the shipping was super fast. I order them Christmas day, and they arrived in perfect condition 6 days later (China to Florida). I am now looking into hanging these lights. I need them 16 inches away from the wall to be centered over my 90. The lights aren't too heavy, would I be safe to use a wall bracket like this and drywall anchors? The studs in the wall won't work, so I will need to use some sort of anchor. Is 5"-6" above the water line what is recommended? Thanks!

There's an even better option at home depot that I used over my cube. Get rubber maid twin-track uprights and brackets. They also have an anchor kit for it.

It hangs just like a shelf bracket, but it allows you to raise or lower the bracket on the twin track. Very helpful with a non adjustable hanging kit like the d120 has. I made a how-to in the old chinese thread that was closed.

Do you have a link to this post? I tried to find it, but couldn't. I am looking for options other than the bent conduit route.

Question, I have 3 nova A4's on my tank. Standard build. Blue cool white. Well my corals look like they are mad at me. I recently bought some new corals that where under t5 at store and I put them on bottom of my tank 30 inch deep tank and lights about 6-8 inches off top of tank and they now won't open. All water params are fine. It was a hammer and Duncan I bought. Could it be lack of spectrum from the fixture?
I'm at a loss

Probably not lack of spectrum. Corals use blue and white more than anything else, which is why those colors are in your fixture.

How deep is your tank? I'm not familiar with the Nova A4's. I assume they are 3W leds? Do you know the PAR values in your tank?

I've used my PAR meter on other people's tanks who have leds and thought they had too much light and dialed their lights down. The PAR meter said they didn't have nearly enough. Two guys were sure they were bleaching their corals from too much light. One guy had PAR numbers that were in the 200 range just under the water surface and in the 20-30 range 18" down at the sand!

Also, even with perfect water parameters, corals take some time to settle in. It could even be your water is way better that the store and they just need some time. I got some uncommon species of green star polyps from a guy and they took a week to open up in my tank.

Good luck.

Just got done swapping the LEDs on my d120. Super easy about an hour and a half for 24 LEDs. took out the cool blues and added 10/7500k,4/3500k,2/660(left off the optics on these),4/450 blues and what I thought was violet 420 turned out to be green..(is that right 420 is green).. I think reefbreeders mis bagged them but all in all I really like the color at equal intensities it's really close to my Phoenix..

I had originally just RB/CW and 4 violets. I knew the violets were burned out so that's why I got those 4. They still lit up but the tops were brown/black and. Ery little light was coming out of them. I am gonna do a warranty claim for them as I took pics of them so hoping they will honor it and send me them out so I can add that back to the spectrum.

All in all super easy to do if you have ever soldered its a piece of cake. If not watch a few YouTube vids and you should get the hang of it quickly. I had to have my Weller 550 up 100% to get the melt FWIW.. I have a few pics of the optics and heat sink if anyone is interested in them. The optics just snap on and off. I'm really diggin the aesthetics of it now with the four greens in it. No spotlighting at all. Left the reds optics off for fear of it but I could have prob left them on. Light is about 4" off the water running back down to 50% both channels nist in case . I will slowly bring it back up to the max I had it 70% blues and not sure on the white channel with the new additions to it.

420 is violet. 520 is green.

Thanks pThat's what I thought.. Oh well wasn't planning on the green but it looks good to my eye. We will see how the coral responds. Gonna put in a claim to sunny anyways. They seemed like they were giving me the runaround before when I asked about getting them. I'll just push a little harder. Guessing it will just happen again though like the other violets burning out. Wonder why only the violets burn?

They started using newer, different violets, because a lot of people/companies were seeing the same issue.

And both the violet and UV always look very dim as they are very close to the limit your eye can even see. But the corals do use light in those spectrums.

I'd like to see a small light with just violet or UV (or even a mix) an put them over some corals at night to see if they light up enough for us to see the corals, and to see how much the make the corals glow (if at all). I'm running my moonlights at 1%-2% with the 450nm lights they use. I'm considering switching them out for violets to see what they do.

reefbreeders IT2080's have been shipped. I might get mine tomorrow

My violet were pretty bright FWIW. Not sure if it was the same as all but they def put off a purple light in the tank.

My two it2060s shipped today!!!! Can't wait!

[lbannie]

My it2080 will be here tomorrow!!!!!!!!!!

[blue98ls1]

I've been in extensive discussions with Ron Reefman (helluva guy, BTW) and am really looking forward to ordering some IT2080s in the near future.

Those of you that just bought some, how was the ordering and payment process?
