Chinese LED Lights

[bobamike]

here is the led setup on the 32'' fixture I am going to get from reefbreeders,in total what kelvin will this arrangment be? 7500k-20000k.
channel 1; 16 7500k cool whites, 8 3500k Warm Whites, 4 480nm blues, 4 520nm greens, 4 630nm red, 4 660nm reds, and 8 410-420nm violets. Channel 2; 48 450nm royal blue, Channel 3; 3 480nm blue moonlights, for a total of 99 3 watt LEDs.
and is there any recomendations from you guys before I place this order? I like the 14k look in the pic above and I to plan to have alot of zoas in my tank and I want them to pop but still have a daylight effect with the ripples on the sand bed and all.

Apologies to you and Sam (the man), just rechecked my Email, and it was Sunny that I was thinking about!

Bhazard,

Would you still recommend the D120 for an sps dominated tank? I was thinking of 3 over a 180g. What lenses would you recommend for this size tank with 3 units? I see they are only 2 watts each... but it looks like there is enough par for sps's even 12" below the surface. Just looking for clarification I am reading everything correctly.

Thanks in advance.

YMMV with an SPS tank. If you have for instance $10,000+ worth of SPS, I would be hesitant to switch to leds in general if you've been using MH or T5 for years. I haven't killed any from the lights, but I have very few right now to go by.

If you don't have many and are willing to try it, 90 degree optics and a 120w chinese box can work.

My first idea was 4 of the D120 over my sps/lps 180g tank. I needed 4 because I have a wide thick glass brace, so I'd do 2 on each side. But then they came out with the IT2080 and 2 of them will fit my tank just fine. I'm doing the standard 90 degree lenses and bougth some 60 degree lenses just in case I have something that needs the light and is down by the sand.

Good luck. EverGrow treated me pretty good. I just hope they ship as estimated, Jan 20th!:bounce3:

when looking at your light when its turned on, can you actually see the difference in color between a 450/440/460nm led? I ordered a mix but they all look like RB. They could just be too close to tell the difference though

Hi guys,

My lights came in and I got this suspension hanger today as well. I'm impressed with the color and shimmer. I love these new LEDs.

You won't be able to tell the difference visually

Looks great. Can you please provide info on your hanger system (where'd ya get it, cost, DIY?, etc.)? Thanks.

Thanks man, I burned my retina today trying to see the difference but couldnt see more than a couple random leds were a bit more dim than the rest.

Also I have 2 reds and a heavy blue to white ratio in my fixture but it has a purple tint to it. when I cover the 2 reds and a couple of the whites I get just about the 20K look I want. Any idea how I can keep at least one of the reds but not have that purple tint?

 

[Ron Reefman]

What lenses do you have on your lights and how deep is the tank?
Do you see the purple as an 'over all' purple or is it a bit more of a 'spot light' of purple in a bigger field of blue/white?
My thought being if you have 90 degree lenses, you might pull them off the red leds. That would spread the red out more and make it less purple.
It's funny because I have a friend who wats the purple rather than the blue look when just his blue channel is on. He has 4 red leds in an IT2080 fixture (waiting for delivery) and he wouldn't put any of the red in the blue channel. I tried to convience him, but he wouldn't do it. So maybe now he can swap a few leds around when he gets it and have 1 or 2 reds on the blue channel.
Thanks for posting up your results.

Thanks Bhazard and ron

I currently have 24 crees at 700ma over a 55. Just cw/rb. I actually have had good success over the last two years with this set up. Im upgrading to a 180. I will look into the it2080. I was just wanting to confirm these fixtures are sufficient for sps's

 

[latinyoungn]

i actually prefer a purple look to blue lol. I am hoping mine comes out like that :lmao:

My experience with leds is very limited, buy I sure have learned alot in the last 2 months by reading here and on the internet and by putting together a good size group buy with EG.

But one of the members of our group buy has old blue and white only, not dimmable (and lower PAR than my old D120 or my ETRadion) over a 220g DT and his sps and lps are doing just fine and showing good growth. He just upgraded because the IT2080 offers so much more control and he gets the color layout he wants. And then he'll be selling his old leds at close to what he is paying for his new ones!

ron reefman, did anyone in your group buy put some whites with their blue channel to break the windex look?

i purchased a D120 a few months ago to test on my tank. one side is still MH 14k Phoenix bulb and the other is the D120 with 24B + 4V and 17W + 10B (royal blue, cool whites). i am unable to match the phoenix bulb look with this fixture even when i dial up the white channel and decrease the blue channel. the led fixture looks 15-20k and the sand has a slight blue to it versus white sand from my phoenix bulb. 2:1 ratio RB:CW is not 14k in my opinion. i actually like the 17CW + 10RB all by itself.

i do think that the D120 leds are fine for SPS. for this reason, i am considering another D120, but i'm not sure what set up to go with.

can you type up what D120s you ordered, their layouts, and reasoning? i want to match the phoenix 14k fired by ice cap pendants and ballasts. thanks

 

[James77]

I just placed an order for the D120's from ReefBreeders for 199 each with the 90 degree optics. Could have saved a few bucks elsewhere, but he is in the next state and I prefer the support possibility. I saw these lights over a persons house i bought an anemone from. Not bad at all color wise, and he had multiple gorwing RBTA that looked beautiful under it. Slapping them on my 75g...

Nobody put any whites in their blue channel. And I've probably said on here that I think (remember, very little first hand experience) that a 2:1 blue to white would be about a 20K color. I would have hoped that by dialing down the blues some you could get back to a 14K look, but then you do have a 1:2 blue to white even on the white channel. My personal experience is with an old D120 that has a 3:2 blue to white and no dimmers. So at full power I have a 14K look. You might look into changing out a few of the blue leds in your white channel... maybe 5 or more?

Good luck and let us know what you do and how it turns out.

thanks ron, im not sure how many whites to put on the blue channel so that there is not a windex look with just the blues on. also trying to avoid a few white spot lights if i have the wrong mix.

i have 4 t5s that i would like to decommission with the MH set up. with the t5s running and just the blue on, it looks fine. but blues alone looks like windex.
