No white light

[NS Mike D]

it is a blue LED covered with a phosphorous layer. This Picture show a typical spectra for a low Kelvin White LED

My max settings is 80 % of amber, cyan and 100 % of the other in this matrix

i have cheap fluval marine and sea on my 29 gal standard. this thread had me thinking that while it has blue and red leds, it's dominated by white leds and if i am going to continue to add sps and other light deamnding corals into my mixed reef, perhaps i should rethink my lighting.
i have two sets of light with significant overlapping with each pumping out the following PAR according to fluval

376 @ depth of 3″ (76 mm)
222 @ depth of 6″ (15 cm)
90 @ depth of 12″ (30.5 cm)
47 @ depth of 18″ (46 cm)


here is their blended wavelength

even though it's white led dominated, to me, the blended wavelength appears to have mitigated the imbalance of typical white LEDs, but i wold be very interested in opinions of more experienced people - would you consider these sufficient for more demanding corals? Assuming good water chemistry, would these encourage good growth and color?

edit note: the coral and fish are not mine, they are part fluval's posted picture of the wavelength so they made the trip to this post.

I tried running 5 flood lamps at 30k. Took out the whites and the large devils hand and star polyps did not open well. I added a little white and everything just opened up?

So many of my best looking corals might as well be thrown in a dumpster for all blue lighting. I mean, yea... if you want to stock a tank purely around royal blue fluorescence go for it. Some of the best stuff (at leas with acros) is only appreciated with some white light.

What’s the percentage of each color to achieve that?

FYI - Since nearly a year ago - I have change to mitras LED bar 2 and hav white phosphorus LED in my setup Mostly 8000 K but also some 6500 and 4500. Mitras LED Bar 2 also have true RGB LEDs - so I can create a white hue even when I do not run the phosphorous coated white LEDs. The RGB give me good good reflecting colours too - my pyjamas still look very good.

Did your corals survived/flourish under just the RGB lighting?. I can control my individuals colors but to be able to come up with a “whitish hue” the mixture is 100%royal blue, 100%blue(cyan), 100%UV 50%green and 25%red. The cool white and warm white are completely off. I’m using the dynamic Focustronic Focus 1 lighting
It’s mounted 10 inches above the water surface and tank is 24” deep.

Yes they was going good below my Pacific Sun fixture. I love that light. But it was bought used and it was singing its last song. I love the light but not the interface and the quality of the fixture. A fan was stopped and a module was broken. I decided to go the fan less path with the next fixture - but I want the RGB option. The only one that meet my whises was Mitras LED bar 2 and I run Profilux before - hence the choise was easy.

With my current RGB setting, it more or less gives a “22k” look to it. Hopefully it will also help with algae control with this setting.

This is what I'm running with the hydra 26 HDs.
Same percentages as my LFS who has incredible growth on sps and lps.

Curious as to why You run UV so low? Any benefits doing so

Hi all
I was just wondering if anyone runs their lights with no white, just blues, uv, red and green?

I do and have the best results in 20 years
