Dialog to this thread is a continuation from another thread that went off topic which can be found here. http://www.atlantareefclub.org/forums/showthread.php?p=700302#post700302">http://www.atlantareefclub.org/forums/showthread.php?p=700302#post700302</a>
Dave, (Acroholic) my comment directed to you in the above thread was meant in playful banter. Nothing more. In person it would have been accompanied by a chuckle and a couple elbow pumps to your ribs. Sorry you took it the wrong way.

I missed this on their website. I could have missed it. But, they claim each of their units is equivalent to 270 watts of MH. If that's the case you and/or they are suggesting 1070 watts of MH for a 120g tank. Wow.
My entire issue or "beef" (as you would put it) with AI is with the fact their claims are FALSE! Be it their posted charts or verbal/written recommendations. Looking at their chart alone, common sense will illustrate that. Chart I'm referring to being here: ([IMG]http://www.aquaillumination.com/sol/performance.html">http://www.aquaillumination.com/sol/performance.html</a>) Off Aqua Illuminations website.

So,how does a rectangular shaped module produce a balanced spherical foot print of light? I'm no geometry wiz but I would call that a misrepresentation. (The only possible explanation I can think of is: The only pucks generating relevant light for PAR are the inner four with the 40* optics and the four outer 70* pucks are just there to help wash out the intense columns of light the 40's produce.)
But, I measured my PAR directly beneath the fixture with all 70* optics today and got 300 uMol in the sand bed (22" down with three units) at 100% power. The 40* optic theory is debunked.
You bring up the fact I've got two units on a 120g tank 47x24x25. (Had to do a custom tank to fit my space) BUT, you don't mention the fact I've got a coast to coast overflow that's 6" wide thus reducing my usable area for corals to 18". (Another mistake! That overflow! Wish I would have done it differently) I had the AI units running lengthwise on the tank for majority of the time I had two units. Per the claims of the graph attached from the AI website, I would need 2 units and you would need 6 to achieve 160 PAR or better at the sand bed for 99% of my tank and 95% of yours.
I could go on and on but I think it would be beating a dead horse. My bottom line can be summed up in a simple analogy.
If I went to a car dealership and said, "I have a boat weighing 8000 pounds that needs towing and I'm looking for a truck to tow it."
Then, the dealership sells me a truck and they say, "This truck can tow it no problem." They even show me nice documents saying how much it can tow and its massive engine power. I bring the truck home and I can't even get the boat out of the driveway. I go back to the dealership to complain and they tell me, "If you buy another truck and daisy chain them together you could then tow the boat for sure."
People need to know when a manufacturer is not living up to its claims. I take every opportunity to do so. I have no doubt if you throw enough of these units on any given tank you can grow any coral. I never claimed to be starting a referendum on the viability of LED's to grow things. I've said that you <u>can't using AI's claims of performance.</u>
You can prove me wrong by running six units on your tank (72"x36"x27") and get good growth and color. This would put their performance claims to the test. Anything else is you buying multiple trucks to tow your boat then tell people how great the truck is.
You can blame individuals tank parameters or white to blue ratios all you want. It's irrelevant if the product can't perform like advertised.
Since I was tricked and now invested, I added a third unit two weeks ago in a last ditch effort to have great growth and color without the drawbacks of MH. I really want these to work for me. After being into my lights for $1,500 myself, I want nothing but a good outcome.
Oh, and Dave, as for pictures of my tank to illustrate a lack of growth. To use another analogy, if I claimed my wife looked just like Cameron Diaz people would want pics for proof. Not so much the case if I claimed my wife looked like Roseanne Barr. Just saying.
