chinese led lights

[Mr Neon]

Is there any point in getting UV leds installed into these units as well? I thought I read somewhere that UV light is not good and will promote algae growth like MH and T-5 give off.

I am planing once again to order another fixture but like the controlling one and Twilight seems to have more options as well as led's available so I want to be sure and get the most for my tank.

BTW, I am selling my D120 once the other unit comes in.

UV/Violet 420nm is good for coral growth. What don't you like about the d120? My two should be arriving tomorrow.

I need the 60* optics for the depth of my tank

Great looking taank seti by the way what is your ratio of led in your DIY

Great thread you guys. I built a DIY fixture a little over a year agao and am very happy with it. However, the D120 fixtures intrigue me because of their clean look. I have a ~145gal 3'x3' cube that is rimless and open on the top. My current diy fixture is ~14K and is growign coral real well. I have no doubt that these chinese LEDs are capable of growign corals with great colors. Im tempted to get 4xd120 lights for a cleaner look than what I currently have. I have read how a lot of ppl on this thread are liking their fixtures and that is very encouriging. Here is a current pic of my tank under the DIY fixture. Im using 3watt chinese built LEDs I got from Steve's LEDs. Would like the fixture about 18-20" above the water level so I think 60 Degree optics would be the way to go. I would probably need 4 D120 fixtures or would that be an over kill? Has anyone ordered these with 60 Optics? How high are you hanging these.

Nice tank you have there. The fixture I am getting has the 60 degree optics, the whole reason I got them is because I have a SPS and zoa tank. Will post some pics once it arrives.

Those pictures file are not too big...not sure what happened. Anyway, I did resized them. Hopefully, they work this time. The third pix is 100% blue, fourth is 100% white, and last pix is both on at 100%.

newe70, Are you happy with the 120 degree optics on your lights? I am ordering the same light you have and planning on hanging my lights 6"-8" off the water as well on my tank. I was wondering weather i should go with 90 degree optics or stick with 120. What do you think?

I have a 90 degree led angle. I did not order the optic lens, since my tank is only 17" high. Both light fixtures have a 90 degree angles spreaded very nicely over my 48" tank. I just adjusted to 7 1/2" high from the water surface. The optics lens will provide better penetrations if your tank is 24" or over.

I am very pleased with the royal blues color and my ratio. I was worried that it is going to be very blue, but they did not looked so blue at all, IMO. All of the residents in the tank looked happy, especially, the frogspawn showed a very nice purple tips, both of my Ricordeas were really popped out. My zoas and gsp also showed a very nice green. I did not noticed much on my sps yet...too early to tell. Today is the first day that I am ruining on these fixtures. I am watching closely to ensure that I do not bleach my sps. And will gradually adjust the dimmer higher.

I got my 2 D120s up and running. Pretty happy with everything. Seems built well enough, fans work well,... ordered with 30b, 22w, 3violet with 90 deg optics. Crappy pic with everything dimmed equally ~15-25%.

I like you hanging diy fixture...can you post a close up pix?

Looks good!

Since, my two new d120 did not equip with the moon-light. So I added a strip of the low voltage led to create a moon-light.

Yea, I will try to get some tomorrow. Need to clean up the wires a little. Was going to paint it black, but the metal matches the aq trim and shelves and I was getting burnt out quick so it did not get painted.

The moonlights are a good idea. I run the small clip on light on the side (refugium) at night. A small angled beam makes it into the main tank for a little moonlight.

Anyone use this one yet?

So I have been planning on ordering two of these lamps for our 75g. Which manufacturer is putting out the best product? I don't mind paying a little more to make it last ect. At first I was thinking get the d120's but then I heard the a4s had better finned heat-sinks.

Who's currently making the best light?

 

[terancevan88]

K my tank is 20" tall with a 3" sand bed so 17" from top with 5-6 inch tall canopy with hanging it will be about 3 inches from water unless I cut the top to plug the lights in.. My question is the optics which should I use...please help I have no idea

Ok so I'm pulling the trigger on these lights this week and every time I think I know what I want I read a little more.
Can someone tell me difference between d120 and a4 as I'm leaning more towards the a4 now. I like the twilight controller built in idea but I'm worried if the LCD controller goes bad the whole u it does.
