I was planning on using some Kessil A360X's for my new build, but I think I'm going to order the Reefi Uno's instead. It looks really promising and at a really affordable price point.

I will after I get some chores done.I just bought 3 Uno's to run over a 48" tank and am considering purchasing a 4th and running 1 on each side of the tank with 1 light behind each. Essentially like a Duo puck setup.
My only concern is the color these put out without having to dial back a bunch of the channels thus lowering PAR. This light has 48 or 67% of its Leds in the Violet spectrum. I love the crisp blue look of the Radion Blue g5's at all channels driven @100%.
Would the Uno be very "Violet" leaning rather than "Blue". On this version they have even lowered the amount of Royal & 470nm Blue leds vs the Duo further concerning me. Royal blue IMO being the most eye appealing spectrum (should be a substantial part of the spectrum)
I cant stand the old VHO fluorescent tanks that have that Violet/Pepto tint...I want crisp/pooping blue. I can obviously turn down the Violets to tone it down but theres not enough royal blues for PAR at that point.
Can anyone comment?
Well light was designed for heavy violet.I just bought 3 Uno's to run over a 48" tank and am considering purchasing a 4th and running 1 on each side of the tank with 1 light behind each. Essentially like a Duo puck setup.

Thanks Dana, I hope this means your life/house is starting to get a little more back to normal now (whatever "normal" means this year Can you comment on the look of the light @ 100% power all channels or is that too subjective (I would ask Daniel but I think he's in R2R jail)?When running the Uno at 100% power on all channels:
UV-A = 6.3%
Violet = 27.6%
Blue = 40%
Green-Blue = 2.4%
Blue-Green = 2.8%
The 400nm LEDs (4 of them) at 100% = 71% in the UV-A range, 20% Violet, 2.3% Blue.
Four 420nm LEDs at 100% = 3.1% UV-A, 80.1% Violet, 12.2% Blue.
Four Violet LEDs = 1.2% UV-A, 60.7 Violet, 33.1% Blue.
Ten Royal Blues = 0.9 UV-A, 4.9 Violet, 88.3% Blue,
Six Blues = 0.6% UV-A, 0.7 Violet, 73.8% Blue, 12.8% Green-Blue.
Thank you or much. To say the last month has been a stressful trial would be an understatement. The roof is still covered with a tarp while I wait for the insurance company to make their move. Fortunately, it hasn't rained much, but the weather report says that is about to change. Well, enough for that. On to the important things in life - reef lighting. LOL.Thanks Dana, I hope this means your life/house is starting to get a little more back to normal now (whatever "normal" means this year Can you comment on the look of the light @ 100% power all channels or is that too subjective (I would ask Daniel but I think he's in R2R jail)?
I just attached a photo.Me too... Would appreciate your thoughts of the light look @ 100%.
Well. Photos can be a bit deceiving.. Is it a violet toned 14000k or blue toned 14000k ish?I just attached a photo.
Spectroscopy shows bluish with violet (40.9% v. 27.6%, respectively.) I've got a chart that I'll publish later that shows the Uno covers a 2' x 2' surface area very well, with little spillover (<100 microMol/m2/sec/)Well. Photos can be a bit deceiving.. Is it a violet toned 14000k or blue toned 14000k ish?
Photo def iooks bluish but with a violet rim.
Almost better to judge by spill on a white wall.

You've heard it from me. Testing is tedious and time-consuming (taking weeks to gather data, analyze it, graph it, insert it into a written report) and life can interrupt my best laid plans.Where have I heard that before.
The relative sensitivities peak at around 600, 550, and 450 nm. We see these wavelengths not as red, green and blue but as violet, yellowish green, and reddish orange. The nominally blue peak is well separated, but the nominal red and green peaks are relatively close. The color we see as green is not at the peak of the green curve but at the minimum of the red curve at 500 nm. Observed red deepens as we move from the nominal red peak at 600 nm toward 700 nm. Color depends more on the ratios of excitation of the 3 types of color sensors than on the absolute values.
The red receptors have a second, smaller peak in the blue range, so blue light excites the red receptors even when no red light is present. The color we see as blue lies not at the nominal blue peak around 450 nm but at the maximum ratio of blue and red sensitivity at closer to 475 nm. By 450 nm blue has shaded off into violet, which carries a hint of redness quite different from that of magenta.
Thank you. That photo clears up all of my concern. That spectrum looks perfect.I just attached a photo.
