DIF-100 with 120 degree optics over a 4'x4' tank. I'd like to see a Sol or Radion do that.
At the same price point? 2 AIs could easily do it with likely higher PAR #s and more even coverage. That's a wicked hot spot in the center. Any PAR numbers for any of the tanks you posted?

As far as I can tell the only difference with the XP line is the addition of various colored LED's for a fuller spectrum. Wattage and coverage is still the same. In a 24" tall tank your looking at 12" AWL PLUS the 24" tank depth. That's 36". You state in the above quote that 120 degree optics at 24" will still put out more than enough light to grow SPS on your sand if you wanted to. So your talking of a 12" tank with the light 12" above the water line. Unless you meant a 24" tall tank.
In that first picture you posted that's a 6' x 3' Tank if I'm correct. It has 3 100's above it and yet the corners are substantially darker and it c an be seen on the sidewalls where the cutoff is. If they truly do light the area you say than 2 should have been more than enough and not had the darkened corners.
As I said I am contemplating moving to LED's so before spending the money I want to make sure I have concrete facts and figures. I currently run 2 250W 20K radiums in Lumenbrite Reflectors 14" AWL and I average 300 PAR on a 24" tall tank. At 500W you could understand me looking into LED's but I have a hard time believing a single 100 will cover my 48"x24x24 and give me comparable par values. I'm only spending this kind of money once Lol.

The light pattern is going to depend on the optics be used. We normally use 60 degrees for our applications since we normally do much larger aquariums and need to punch down beyond 3' of water. PAR is also not an absolute rating when it comes to lighting, there are other aspects.
Here is a link to a WWM review of the DIF-50XP unit. The number of chips in the 100 is doubled so you can expect to see double the amount of PAR at the listed points at the bottom.

The other thing to consider is that photographs aren't necessarily true to life when looking at the volume of light emitted. Most pics are going to be retouched to reduce glare to some degree otherwise they would look very washed out. Anyone who has taken pictures of an aquarium will tell you that playing with the settings on the camera or after the fact is the only way to get a good pic. We use these lights ourselves because they are powerful enough to do what we need and they can be adjusted with optics for the smaller applications. As of yet Orphek is the only company to produce viable LED technology for the larger installations including a several million gallon aquarium slated to begin construction in 2014. Orphek is currently working on designs for a 1,000w halide replacement or bigger for the project. Name one other company that has researched and designed their own diode technology as opposed to slapping in the same Cree/Bridgelux components as everyone else.

120 degree optics will give a larger spread the units pictured are using 60 degree optics which will give you a 2'x2' usable footprint which is why in a 6' tank you would use 3 if you were building an SPS tank like that. For a small 75gal rimless a single unit with 120 degree optics would be more than enough. I was just throwing out the idea as a possible economic option. You could just as easily mount 2 of the 50w units with 60 degree optics but the cost isn't much different per unit.

That would be dope on a moving track like its the sun lol

And dont call my 75 small lolll just got rid of the nano lol.....as for the single canister type lights how do u experts feel about the blue moon aquatics p30?

So I'm still researching lights on all different lights and it looks like to me that most people make a good point that the ecotech radions have more of a light spectrum and there easier to program different settings through the Internet and that a lot of people settle for the ai sols cuz there a Lil cheaper....at the same time I see a lot of people have the ai sols and love them....I really want what's going to be best for a Sps only tank.....and again I'm trying to be patient with the vegas lights...but there aren't even specs out on them yet.....I'm starting to get itchy waiting for them

everyone has an opinion on lights you should go with results see who has what and see there growth and color

You just want me to get your lights no im jk lolll I agree...I'm trying to get feedback and it's kind of evening out
better to see it yourself. depends on your eye satisfaction. but for me LED is still good. :yo:

I would just go with radions, AI are good but only give you a 12x12 spread , Radion will give you a 24x24 spread and the right color spectrume ,Thats why the reds and greens are there to fill in for the lost color spectrume that the AI and other leds couldnt fill, Thats why AI has the new fixture with the reds and greens know, And echotech is releaseing soon a phone app to controll the radion thru your phone and not your PC.
