chinese led lights

Oh hey I really like that first one and the bottom one. I think the bottom one has 2 less whites but still 3 more than the stock. That lower one looks ideal.

I too was wondering about how they have the reds staggered. I also think more than 4 violets would be too much purple from what I've read.

If you don't mind I'll just use that lower one.

That was the easy part, now you need to pick out which whites and blues you want. I wish I could take a picture of mine to show you but I don't have a clear sided tank and can't get a good picture from the top (reflection). I don't even know what they really look like yet.

My nitrates are still a bit high, but I've noticed that I've been growing algae quicker with reds and greens along with my NW/WW Crees. I may cover up or remove the reds and greens if it keeps up.

what what??? DOH!

 

[cmantis]

I don't think 3 reds and 2 green will really grow algae may be the warm whites. I haven't had my on long enough to determine yet.

What blues? I'm getting the one that's not moonlight. Isn't it royal blue? How many different blues are there?

As for whites I'm just going to split them evenly between cw/nw/ww. 6 each evenly distributed. My plan anyway.

Now I'm wondering if I should say no to green and just get a couple more blue or violet.

I've been using RB with 10K CW for 8 months and am not missing any colors. My color looks like a MH bulb a nice crisp blue/white. All the other setups I see with NW/WW just looks too orange to me. I say stick with RB/CW to me those other colors don't add much.

Question: Can we get the same effect as Cree LEDS if we use multiple Bridgelux LEDs?

Bridgelux same as Cree leds just less light intensity. But give off about the same amount t of par.

Maybe something like this:

oops I forgot purple=420nm

I was wondering if that was going to happen. How high are your nitrates and are they much higher than before you changed out the fixture? Do you have a sufficient cleaning crew? Im just wondering if there could be any other changes besides the reds and greens, but I have heard and seen very similar results when adding reds.

It could be because I'm using WW and NW now, that the reds and greens themselves are no longer needed, and spiking the spectrum used by algae for photosynthesis.

I ran rb:cw for a few months as well. I am currently running a DIY with nw:ww, violets, and other colors like cool blue and cyan added, and there is a huge difference in color... especially in warmer red/orange tones, purples, blues, and greens. They practically glow with color now. Same couldn't be said for cw:rb.

I was curous if anyone else had experienced this. I dont know if its the red/green or just the huge jump in lighting power. I had recently switched from PC bulbs to LEDs with the green/red and have been experiencing significant GHA growth. My nitrates and phospahtes read zero but I know that cant be true.

I still love the light and can dim or turn off the red/green if I decide to. I am increasing my inadequate CUC and hoping the excess nutrients will get 'burned off'.

I don't get much GHA at all. Its some cyano and diatoms on the sand, and probably related to my elevated nitrates. Phosphate levels are good, but there are still probably plenty being absorbed.

Pick up a cleaning crew. You might have unbeaten food, or something is decaying in your tank. Maybe under in rockwork or in a water current dead spot.

Reefcleaners has some good deals or you can shop around local. Atleast get couple crabs and hermits.

What whites do the evergrow fixtures use? I am very interested in two of these units:

Who has ordered a full spectrum D120?

 

[Rjiowa]

I'm interested in those also, but I'm worried they might be too blue. Other posters have said a 2:1 blue:white ratio was to blue and they had to have one dimmer turned down which seems like a waste to me.

By the way, thanks to all that contributed to this thread. It's a long read but very informative.

Cmantis, have you been experiencing an uptick in any algae growth, i.e.- cyno or GHA? I know you have a few red, green, violet and WW in your fixture I believe? Maybe too early to tell yet?

Good discussion here with the new LEDs available and seeing how the color variance/distribution (reds, greens, violets, WW) helps with coral and fish color, coral growth, or the adverse effects of algae growth.

OR- might it be due to other factors such as water parameters relating to ammonia, phosphates, nitrates, etc. Is there a sufficient CUC, all of which are very relevant aspects to consider? I am guessing many of you are simply just replacing MH or CFs, in which case you could easily tell how the only the addition of your new LED fixture, given your prior routine didn't change, has effected your corals?

Thanks guys, and keep it coming for our fellow reefers.

I have 50+ snails and a few hermits in a 34 gallon. I also have a Vortech MP10 and have an RO/DI unit. Cleanup and flow are not the issue.

They use whatever whites you want. By default, they will use Cool Whites 10-12k.

If you stay with cool whites, you'll need the reds and greens for a spectrum boost. If you choose neutral and warm whites, you may not need the extra reds and greens. The violets are very useful though in all builds.

Way too many variables to pin down, but my new tank is less than 6 months old and I added a lot in a short time frame. Originally before I rebuilt it, it ran MH/T5 for 3 years. Nitrates are higher than I'd like from the bioload I transferred back into it.

I cant pinpoint specifically if extra colored leds are a cause yet because of the nitrates. My DIY Cree Nova is also running at almost twice the power too (180w). I'm going to try running without red/green for a bit since I also use neutral and warm whites, which have more red and green in them over cool white.
