I would not worry about it too much, I didn’t see any difference when I installed a radion over my tank (water is pretty clean). Red leds won’t hurt your corals as long as  you have much more blue over it as it is the ratio who is relevant. The problem I see with that light is that it must be too much pink. They could have put a green led to balance the white for the eye.

Dear lord…

The red LEDs aren’t going to cause an issue. I have been RGB over my tank for at least 6 weeks now and using some magenta LEDs. Algae has not increased and my corals are doing just fine.

Think of the Fiji Purple type T5s. They have more red than a couple LEDs and cause no problems for people. Good water quality is much more important than lighting when it comes to algal growth.

I agree with this. I would have run 8 blue, 3 white and 1 red. The red would be right in the middle with no optic on it. This would allow the red to spread out better.

lulz all around

Do 3D glasses work on this video or ????

Is this a “what was I thinking” moment.

And this is reefbuilder news because…..

IMO, looks extremely tacky.

IMO only 1-2 red led’s 7 blue led’s and 3-4 white led’s would be nicer. The squirrelfish/soldierfish look great under the red led’s though.

That same article shows that the sun has a very high percentage of light within the red spectrum.  Obviously the sun can grow coral and doesn’t inhibit coral growth.  Yes, red can grow algae, but it can also help grow coral.  Chlorophyll A peaks right around 660.  Fiji Purple and purple plus bulbs have plenty of 660 nm red.  I wouldn’t use only 660 or even more than 1 per 10 LEDs or so (I think the ecoxotic light might have one 660 LED too many but that’s a matter of preference), but in a small quantity the deep red/hyper red LEDs can bring colors out in LED arrays that they’re otherwise lacking. 

In the ocean, corals come from depths where red light is highly filtered out so the majority of the red light from the sun does not reach the corals. In a 2′ deep glass box and putting specific 660nm red LEDs the red light will reach the corals, and can possibly lead to problems with corals. I agree in small quantities Red is very useful, but there is a fine line between useful and harmful when talking about the red spectrum and corals and for me it is not a line I wish to tip toe around. I use warm white LEDs which have plenty of red spectrum in it without blasting specfic 660nm light on my corals.

From the Article:
” Early research papers reported results of coral transplantation experiments, where corals were moved to deeper, or shallower, depths and survival rates were observed (Dustan, 1982). Dustan’s experiments demonstrated that coral colonies transplanted from 30 to 15 m suffered from reduced growth, algal bleaching and high mortality rates. Although spectral quality was considered in Dustan’s paper, no opinions were made about chromatic adaptation, and a conclusion states: “…deep algae are damaged by the high light intensities that occur in the shallows.” (Dustan does show data that demonstrates a general decrease of blue and red wavelengths with increasing depth. And, as a point of reference, Dustan observed high survival rates of corals transplanted from 10 to 30 m.) Two years after the publication of Dustan’s paper, Kinzie et al. (1984) reported results of zooxanthellae chromatic adaptation experiments. Replicate experiments by Kinzie and Hunter (1987) corrected some errors advanced in the earlier work of 1984. Interestingly, the 1987 paper advanced a theory that the amount of incident red light is the parameter that regulates zooxanthellae cell density and, hence, pigment content. This hypothesis (confirmed by results of their experiments) states that corals subjected to increasing amounts of red light will reduce the number of zooxanthellae cells until totally bleached. These scientists used natural sunlight and filters to transmit a broad red bandwidth (~600 to 800 nm). (Note: Coral bleaching has also been seen at a narrower red bandwidth produced by an artificial light source – a light-emitting diode (LED) – Riddle, in press). “

I think we’re really on the same side here.  I saw the part about water filtering out red, but a lot of corals grow in that first two meters of water too.  I was really trying to say that I wouldn’t worry about one or two Deed Red LEDs causing photoinhibition.  
Also, bring corals up from 100 ft to ~50 feet is a huge difference in light intensity.  You wouldn’t drop a deep water coral straight from the ocean into position 12″ from a 250 halide without risking bleaching and mortality.

This looks EXACTLY like the LEDwholsalers PAR38, except black, when is ecoxotic gonna stop stealing ideas from other places…

They look completely different to me. PAR38 just means the style of bulb, not what is inside the bulb. I see no reds in the LEDwholesalers bulb. You can also buy PAR38′s from HomeDepot, RapidLED, or many other places and they have completely different bulbs inside.
