Let me officially say that I love the following combo for beautiful good looks.

1 warm white, 1 cool white, 1 neutral white, 1 royal blue.


I've used this for 4-5 months now and it is extremely colorful.

Here is a fairly low quality pic. It reminds me a LOT of the colors we can get from T5's. But, with the awesome shimmer.




I will be converting this tank to a reef soon, though. I'll just add a few more blues and use a cheap DealExtreme driver.

As for our eyes, I prefer the higher K temp look. Right now I'm using a reef-recycled 1:1 cool white/royal blue over my 11g rimless and even at equal power to both colors, it's not too bad. Too blue, but not terrible.

I prefer to dim the blues down to about 24% of the whites, but I suspect running them all at equal currents in a 1:1:1 (cool white, warm white, royal blue) will look very, very nice. We'll find out in a couple months when I change my LED setup.
No, I just look and am interested in LED's and the various drivers and types. I also dim the blues.....the bridge lux are surprisingly good.

I'll be redoing the various tanks I have with different arrays, 6000K Cree's and the 8000K mostly, maybe some 10K with the 6000's.

I personally like a tank with Cree CW and Neutral White plus some 12,000K BridgeLux combo.

Additional colors are a splash of red and green.

I will add blue only if the tank is for cichlid

Yeah I would probably dim the blues a touch (maybe 30% lower) if I could with that 11g tank, but they are all on the same driver so I just live with it since it looks great anyhow.


If you are using 10K combined with anything, I recommend you try warm whites (3,000K). A warm white LED is much more "amber" than it is "ugly yellow" to the eye...... at least the Cree, Rebel, and Bridgelux are.

A 10K LED and 6000K LED are going to be remarkably similar in blue output, but the red/yellow/amber portion will be quite low, which means the tank will have an overall anemic look, if my predictions are right.


A 10K and warm white combo I imagine would look much more pleasing and be just as photosynthetically useful.

Anyone else have any particular LED combos they've used based on this spectral study?
