P.S. Just read through some of the links you provided via the other thread. There is some great stuff in there and I didn't know about those ESL suppliers.
You are welcome.
If you look at the threads I've started you'll find many highlight what's new in lighting options.

Almost all of the cutting edge lighting technology info I come across I find on the site called Reef Builders. For example: http://reefbuilders.com/2012/07/09/1...on/#more-60222

If you chose the Cree 3 W, they offer decent spread and you can space them out evenly over the foot print, the spot light type things do not do that and tend to add too much light, the tannins will go away, too much light will be a thorn in your side for a long long time to come.

Better to go less, rather than more, with light intensity. Especially a lot of light on a larger tank. Great way to grow algae though.

Hoppy I think you need to step back and start thinking from the start. You apparently can afford $1000 or more for lighting, but you are using the cheapest substrate material you could get. As a result of the substrate decision, you have a big tannins issue, making lighting the tank more difficult than it needs to be.

Why not switch to a commercial aquarium substrate, that doesn't release that much tannins, using some of the money you plan to spend on lights? You can buy a lot of ADA Aquasoil for that much money, and have a proven great substrate, that doesn't give you the tannin problem. Your tank is probably something like 96" x 30" x 30", which can easily be lighted with T5HO, or LEDs. You could use 4 of these 48" lights, http://www.catalinaaquarium.com/stor...oducts_id=1842 in two rows, separated by about a foot, and get about 50 micromols of PAR at the substrate, more than enough to grow any plants.

Then, start planning a CO2 system, which will be essential, and is by far the hardest thing to get right on a big tank like that.

I got it for ya! The prices are below along with a low quality picture of the modules and their design. I will of course be removing the U-Bar in the back as I plant to place it face down onto the top of the acrylic tank and only have 4 inches of clearance from under hood. The unit gets up to only 50 deg C (122F) so it will be a bit hot to touch but nothing the acrylic can't handle.

So its an investment and LEDs last minimally ten years and don't lose much brightness or get very hot as compared to fluorescents and HIDs, respectively.
Well by all means if you need it then go for it. that price just shocked me.

Actually no. The provider I am using is an LED wholesaler for outdoor, warehouse, and Stadium lighting. They don't list their prices on a website so I have contacted a rep directly. She provided me with the following chart and I hope to have the prices for each soon. They seem to be the best, compact, LED floods I can find.

lpsouth1978 I had used 2 100 watt multichip LED's over my 90 gallon reef with great results. That is an even cheaper solution. I did not use flood lenses, but 90 degree optics. It was a super easy build. I think the floods would not be focused enough to penetrate to the bottom of the tank.

Actually not really. The opposite is true. LEDs have about double the output as metal Halides for a given wattage. And I don't want the heat/fire risk of a hot metal halide in my house nor the UV light they give off as its rumored to yellow some acrylics.

lpsouth1978 You might be surprised at the penetration you can get from LED's. plus a metal halide uses more power produces less PAR, and creates A LOT more heat.

lpsouth1978 The problem with $100 lights on a tank that size is penetration. A cfl or even a T5 is not going to penetrate all the way to the substrate. You need something more powerful or at least more focused (like LED's with optics). A 375 gallon tank is a whole different beast.
