So why 3 cooling fans when every brand name led only requires for the most part only heatsinks.

TaoTronics, SkyLED LED Light Reviews | My Aquarium Opinions

My point being they run hot and loud for LED's and also use more energy with less useful energy output.
This article was nothing more than opinion. They never checked PAR or PUR with a meter. They simply state that they aren't as good with no data to back the claim up. I wonder what the motivation for writing this article was, without operating one prior to doing so.
I'm telling you that they work fine. I have proof. My sps looks great. I've been growing coral for a while now and I can guarantee that these fixtures are more efficient than t5 or metal halide and use less energy. The PAR is more than enough to grow colorful sps on the sand bed, 30" away. You can't do that with a 250 watt halide.
As far as purple on the sps...take that fixture you have off of the tank and replace it with a 10k halide. You won't see any purple! It's not the potency of the fixture you are seeing, it's the color temperature.
The clear plastic cover that is over the LEDs is barely warm to the touch.

I'm going to purchase one of the units with reds and greens in them and I'll report my findings.

I'm going to order some as well. My son builds his own lights and he throws in a few red and cyan LEDs. I think his light "looks" better.

The picture is with 14k whites only no actinics
but if you take any coral and place it under10k its not gonna look as good under 14k or even 20k that goes without saying would you and greg show a pic of your best acro under whites only at any kelvin to back up your theory thatd be nice id like to see your results of the lights your swearing by

Grown from a 1" frag in 120 days. Blue LEDs are turned way down for the photo.

Fisheye photo is from a iPhone under my normal reef LED lighting.

Capricornus at 24" below the "cheap" Chinese panel.

Look at my thread where I describe my moving focused LED that generates over 1200 PAR on my frag tank. You can do a lot without spending huge amounts of money.

I just took some photos. I don't know if my tank or corals are the best examples, due to the fact that I am working through a excessive nutrient problem. I'm going to post a few in my tank thread. Meanwhile, the name of this thread is "Lighting your reef, the best bang for your buck", and not, "the best lighting on the market, no matter the cost".
For under 200 dollars, it most certainly is one of these units.
