Lighting Update
Well - I have the poll going and hopefully I will get some more responses. In the meantime I am going to post what I have found thus far. Grab some popcorn!
First, as everyone knows - corals, as well as most all the inhabitants in our reefs need light to survive. They also need light to photosynthesize - make their food. Many of the corals that we house also use this light for coloration. They absorb a specific range of the spectrum and in return produce magnificant colors. Here is an article by Eric Borneman that might be of intrest.

Most of you shoul be able to understand it
Now on to the nitty gritty. After looking at the magnificant eye candy the japanese are doing - I wanted to find out what they were using for light. The rich colors of blues, greens, reds, oranges and yellows are just superb. What do they know that we dont? Let alone, how are they doing it?
In all reality, its very simple. Look at the picture below. It was posted as a link previously -
As you can see there is not just 1 or 3 lights being used in this setup. There are several, 18 to be exact. Each of those lights has its own purpose and all the lights work together as a whole.
To break it down further, here is another picture that sheds some light on the matter.
My conclusions are not based on these pictures alone. However, it appears the japanese have taken reefing to a whole new level. Instead of running just a couple of lights that give 10/6.5k of spectrum, they appear to have broken down the spectrum in several catagories -
1 - Red,Yellow,Orange
2 - Green
3 - Blue
4 - Violet
There also appears to be a couple of other catagories that I can not make out at this moment. 1 appears to be similar to what we use - 10k metal halides - which fills in any gaps that are not covered in the breakdown catagories. I also want to point out that most of these lamps are low wattage. 23-50w per bulb. Their output is phenominal, which I beleive is due in part with the type of reflectors they use. Anyone familiar with the medium size heatlamps that hang from the ceiling? How well that light is pinpointed down? Basically thats what these housings appear to be. Just smaller and more refined.
Since the japanese have done this, they have an advanatge. They are able to give their corals exactly what they need in terms of light. They can move the lights to any desired location and have as many as they want without any heat problems due to this setup. As seen in the pictures, the results speak for themselves. Not only does it give the corals what they need, they are also creating truer, deeper colors with these lights. In the end, the coral is richer and more vibrant because of this. Now, I don't know everything on these lights, this is just what I have discovered thus far and made my most educated analysis.
Some of these tanks have been up for 2 years, some have been up 8 months. Now, not knowing all the infromation from the japanese side, I can tell you that in order for our tanks to even compare to their tanks, would take at least 1 year. Then again, its not even close. Yes, some of the tanks are for restraunt use, but the majority of tanks that I am talking about and have seen are other reefers like us.
Another additive with the setup of lights they have, there should be mininmal algae growth. The reason, since they have broken down the spectrum, they are able to remove that part of it or at least, take it down a notch. I think this would also explain why there is little to no algae in the tanks and maybe perhaps very little to no corraline. Again, this section is speculation. They could also be dedicated cleaners!
Now, when you look at an american tank what do you see? Blue/White light.. some yellow. As with most all tanks in the US there is that basic lighting setup. Metal Halide and or VHO. The problem I see is, we are not providing the most effective lighting that we can. Where as the japanese are. What were doing is taking our corals and putting them under a 6.5/10/12/20/50k spectrum and calling to done. Some of us suppliment that with more blue or white with the use of vho. There are quite a few tanks that have SPS and other corals where coloration is beautiful, but is it as deep and rich as our japanese friends? IMO - no, its not. Why, I beleive its lighting.
You can't put a group of corals under an umbrella of light that gives a little bit of each part of the spectrum and have amazing results. I also think to achieve somewhat deep color, the amount of light has to be increased to allow more of each part of the spectrum to get to the corals. In doing this, your creating alot of waste. Your producing excess light, using more energy than is needed and having a moderate impact on the requirements of those corals. Whereas again, if you break down the spectrum into different catagories - bulbs - you have the ability to provide your inhabitants with exactly what they need at a much higher percentage without the added addition of heat and power.
The by product of this arrangement is - a more robust coral - color saturation is much deeper and richer, along with the aesthetics of the tank itself. The colors are MUCH MORE profound.
Thats why I introduced the MR-16 bulbs. A way to introduce color and depth to our tanks, as a cheap alternative. It has no affect on the inhabitants. However, the japanese are doing the same thing, but their goal is to make their corals happy by providing the correct spectral light and it not only helps with the lighting, it gives the corals exactly what they need!
Please remember this is just my observation from the information that I have in front of me. It may be totally off the wall, or it may be very true. I believe it to be true. I am still trying to get more insight into this - so if anyone has anything they wish to add, lets hear it. I am also going to try and find out how I can get ahold of some of those bulbs, specifically, who makes then and if they are exported. Hopefully I will get some leads.
Well, thats most of it. Enjoy!
