You repeated what I said in 10x as many words with an agressive tone... and then decided certain aspects of minutiae are whats important to show that it's not a twinstar knockoff? So the rgb vivid has a "controller" does that mean it's not a solar rgb knockoff now? What are you even talking about.

(Model. 1200SP)

LED Source : RGB-W
Color Temperature : 6700K
Lumens : 6900lm
Power : 94watts

chihiros wrgb is 6800lm 95W...
I wasn't saying they have like an exact color temp / tone match... but they're trying more for that than matching the just whites of all the non solar rgb ada models. Obviously these aren't par numbers but I would bet they're not that dissimilar.

(I also said you would probably need 2 originally... same as with the twinstar imo hard to do highlight on 48x24x24 with just 1 bar led.)


The reason I called the twinstars ada knockoffs is they originally came out copying the acrylic / fixed width rimless tank physical appearance that ada did and added the adjustable metal legs stuff later, though obviously their diode choices were wildly different from ada...

Agressive tone(?), it wasn't even close to intended that way.

twinstar knockoff
Larger companies that sell 100X more, don't typically knock off smaller little niche companies like Twinstar.

RGBW is already 3rd generation, older than Vivid and the new X series.

Check your specs on Chihiros.cn site, don't rely on sellers as the specs from them are all over the place.

The Canadian Distributor for Chihiros is a friend of mine, I got my information from him, he suggested for a 4ft or 6ft two RGB Vivids, with enough power for just about any tank and a built in controller(no need for the commander).

I'm done in this thread, not sure what your motivation is but I have no interest in arguing with you, you seem so invested in your opinion I'll let you take it from here.

The AI Prime will never color a tank like a Twinstar 1200SP. Buy the Twinstar and be happy.

Their site shows 135W still 6800lm, but I think you're overestimating the sales #s of ada led fixtures... I think even the original rgb is more of a knockoff of twinstars than ada fixtures, though those ones are dimmer.

so you can possibly answer a semi-nagging question:
Vivids advertised as RGBW but the Whites look to be just RGB combo diodes..
No "white" as most would understand it..

Any idea if they measured CRI on this? not real important, just curious..

RGB VIVID series LED light - RGB VIVID LED light system - Shanghai Ogino Biotechnology Co.,Ltd

I see no mention of white? I don't think I've ever seen "official" cri for any chihiros light just maybe one of your spectra things...

apparently doesn't allow linking to chihiros.cn images.

opens when you "quote" btw..

and yea I've "SPECTRA'd a few RGB.


Chihiros Vivid 10000k, 76 CRI , magenta tone R9(sat red) 68

UNSTitan 10000k 88CRI aqua tone R9 (sat red) 42


compared to NuniQ (Korean) RGBW Led:
9350K (listed 7000-9000K), 80CRI, slight blue tone, R9 69


difference is a more balanced CRI across the test swatches and low color toning but high-ish red

grassycore (japanese)
5990K, 96CRI, very slight pink tone, R9 87
not really fair..

"My" spectrum I found and "analyzed" doesn't really look like this .. need to check on that..
http://www.aquariumlightings.com/upl...sycore-2-2.png


Sooo just did the grassycore "wing"..
6580K, 92CRI, slight green tone R9 87

I kind of want to try their cetus 2 puck...
http://www.aquariumlightings.com/upl...Cetus2_2-2.png
but from their listed leds I don't understand where that red spike is from...
and I can only find the cetus 2 reef version which is 219.99 or 209$ can't find anywhere to buy a grassycore or their wing bar led or the fw cetus 2

Think you get the Grassy Core direct from them.

Quote:
Eight colors of LED inside the Cetus 2 include cyan, blue, royal blue, purple and UV, plus a little white, warm white and red to balance out the spectrum.
Guess that's the sw version though..
Hmmm...

Anyways checked their chart "as is"..

Hrm well I would probably use the cetus 2 freshwater over an ai prime or radion but their "distributor" page is basically blank and I have the impression that they come to tradeshows looking for distributors more than they're looking to do individual sales but I guess I'll shoot them a question anyhow. I'm not really trying to start a light reselling business
