I've had the 120w 14k Evolution LED for just over three months now and I have enjoyed it. There are a few things I would love to be different, but in my opinion for the price of this unit you can't go wrong.

The fixture itself is attractive. 119 1 watt LEDs (60 blue, 59 white) are arranged well so that there is nice even coverage across your tank. No "stripes" or "spotlights" of different color lighting. Although early reviews suggested that the fans were very loud, this issue seems to have been resolved before my model was produced. The fans keep the unit cool and are nearly silent. The outside of the fixture is powder coated black and looks modern and attractive hanging above the tank.

The coverage on the sellers website suggests that this fixture can cover a 36 inch wide area, and while I agree that at 18 inches or deeper you will get that wide of coverage do understand that the fixture itself is not very wide. At the edges of that coverage light will only be coming from the direction of the fixture, which will cause corals to prefer to grow in that direction and possibly have different coloring on the side furthest from the light. I would suggest you consider the coverage on this fixture no wider than 30 inches. With two fixtures I believe you would easily be able to cover a 60 inch (5 foot) tank. Three fixtures could cover as wide as an 8 foot tank. All of those numbers are based upon my choice to hang the fixture 5 inches above my water line where I am currently growing SPS 8 inches below the water surface. If you're not interested in SPS, you can hang this fixture much higher and get more coverage. NOTE: I'm sure you could easily grow SPS at the top of a tank with these fixtures hung 8 inches off the water. I chose 5 because of my smaller area, and to get more PAR down to my corals.

Pic Note: This image is from before I added SPS to my tank. You'll see SPS pics later. This image does a good job of displaying the coverage of the light, which is why it was chosen.

The PAR from this fixture is great. It has grown corals in my tank well, and I'll display some growth shots below. I do not have access to a PAR meter, but even if I did I doubt I would do a large write up on it because one has already been done very well for this unit.

Growth shots: Make sure you pay attention to dates. All of them were not added at the same time and pictures were taken on different days. My stocking was just completed within the last week, so from this point forward I'll be able to take exact growth shots with exact start and end dates of all my corals together. While I was stocking, this was impossible. :-)

I ordered my Evolution LED unit from www.thecoralshop.com. I've also ordered many corals from there and they do a great job. Free shipping on the lights also. :-)
