Chinese LED Lights

[ReeferSteve78]

Ok guys so am going to order the IT2080s next week when they get them in stock. Logan called me and said they will have them in next week. My question is I have 3 10k halide and I want the same in the layout for the IT2080 fixture. Can someone either help me with a layout or post it so I can tweak mine up. I want to have a mixed reef tank.

I actually think its more that the blues are a little lacking in strength compared to the whites. The whites measure close to a good quality bridgelux bin from measurements I've seen. The blues lack a bit compared to a Cree or Luxeon blue, therefore more blue is needed.

My original layout with Twilight Group was only 2:1 blue to white, yet it was nearly smurf blue. Their whites were lacking at the time, which I believe was fixed since. The "use this ratio for this color" doesn't really work across different companies or fixtures. There are too many variables involved. For these lights, the standard layout or 3:1 is a good starting point for 14-16k. Neutral and warm whites need even more blue.

My original layout way back in the thread is very 10k at 100%. If you stick with Reefbreeders default or the last one I posted, Whites at 100% and blues at 70% should be very 10k as well. As Travis said, the whites are really, really bright and quickly overpower the blue. Travis, would you say that is 10k on yours?

For these lights 2:1 will get you a 14-16k look ... that's what I went with looking for a 20k look and its not even close but like I said thankfully you can tweak these how u want them ...

I'd say with these units at least a good rule of thumb is

2:1 ratio=14-16k

3:1 ratio=18-20k

But both will not be exact it will be ball park and tweaking will be needed regardless

Will 1 d120 or IT2040 be enough to cover 40g breader n support sps? How high would i need to hang it to get good coverage?

So Travis for the IT2080s you think I should go with the 2:1 ratio on both the fixtures from reefbreeders so I can get the 14-16k look or keep the oringally layout from them.

For a 90g 48" tank, would I be better off with 2 IT2060 to get wider coverage across the tank, or 2 IT2040 so there is more powerful light in the middle part of the tank?

I run a mixed reef and want the ability to have nice color throughout.

Travis - with the 3:1 blue to white ratio, how do the reds fit in. Do you find they add a lot to the look, would you prefer more or less etc?

This may be a dumb question but I am still trying to get my mind around the optics on the IT2040. If I order them with 90 degree optics but decide to remove them do I have the exact same setup as if I ordered with 120 degree optics? I guess I am trying to understand if you specifically order 120 is there some sort of secondary lens that is 120. If it is exactly the same once you remove the 90's I will go that route but I am a little concerned about spread as I will be upgrading to a larger cube in the next 6 months.

@bhaz I'm not too sure I'm not very familiar with a 10k look but I would definitely say it's no more than a 14kand that if I'm running both channels at 100 percent

@reefer Steve I went with a 2 to 1 ratio and that's including my moon lights I'm at 29 total Blues in 14 whites and like I just said it's not exactly a 16 K it's pretty whitebut don't be afraid no matter what ratio you go with you will be able 2 dim the channels to where you like the look but for me I wish I went bluer because if I wanted 2 run my lights full power but still have a 20k look I'd have to run my blues at 100 percent but keep my whites at most 60 percent and realistically that's shooting high being at 50 percent 40 percent on the white would be more where I needed to be... and my units only have 14 whites total ..

Thing is I'm running mine at 60% blue and 30-20 percent white and its plenty bright so you can dim your channels to get to your goal no matter which option you choose ... for a 2080 with the look u want I'd still go 2.5 blues to white ratio

57 blues
23 whites (15 75k 4 35k 4 12k)
8 violets
4 red
4 green
3 moons

I think with that ratio still be no bluer then a 16k and you will have plenty of room for tweaking channels at most you'd run it 80%blues and 60% white.. .

I really feel unless your dealing with a super deep tank there is no reason for these lights to be ran full power to me it's just too bright an intense looking lol

 

[Travis1787]

I have 2 reds and 2 greens In each of my units and to be honest I dont really know if they make a diff or not but I'm not as wise in my led knowledge as bhazard is ...

I do notice some SLIGHT spotting with the red and green more so the green so I'd be very careful with how many you used ESPECIALLY if your using 90 degree optics like I did

Thanks a lot Travis am going to do that exactly. I will be calling Logan and giving him this layout and am ordering my IT2080s so when I get them I'll post up pics for you guys too see. One more thing Travis so I get this right what is a 2.5 ratio?

Just ask Logan for a 10k look. They can also come up with a layout.

 

[Travis1787]

Well see for my light I went close to a 2 blues to one white ratio 29 blues with moons included and 14 white if you divide 29 by 14 you get 2.1 so I'm almost right at a 2 blue to one white ratio ... I wish I went 30 blues and 10 whites which would be an exact 3 blues to one white ratio ... so a 2.5 would be every 5 blues 2 whites so say you were using 50 blues well then 20 whites would make a 2.5 ratio ( 20 goes into 50 2.5 times)

So the ratio I suggested for you at 57 blues and 23 whites is just under 2.5 ratio its at 2.47 but with the moons your at 60 blues and 23 whites which is a 2.6 ratio which is fine ... I think this will be good for you but its not gonna be perfect you will still have to tweak it some to where you like it

double post again... Sorry for all the double posts my phone is driving me crazy

 

[Dbondaruk]

I have a it 2040 from reefbreeders. I don't know what light output would be best. I'm running blue 65 and white 50 at peak hours.
All I have for corals is a frogspawn/dunkin/blasto/birds nest sps/ tiny little acopora frag just to try it out.... Any recommendations on what percent difference would be great for my corals health??? Thank you

 

[Travis1787]

Logan also gave me my layout when I was looking for a 20k look and no offense to Logan cause he was great to me and I will deff buy from him again but his ratio he gave me was not even close to 20k

This is more of a trial and error method to be able to figure out what leds you need to be where you want to be

I really like this layout and how many red green and violets would you go for?

I've experimented with two categories of Chinese 660nm reds... the ultra-cheap bay ones, which had very weak output and visually changed lumens as you looked at them (had to throw them away), and the more standard ones direct from Chinese sites which had high output and were constant and reliable. Not a single failure yet with these.
