I finally got these wired:
Now I need a PAR meter to test them. They are 2x30 watt single LED emitters, one blue and one white.

They now have 50 watters. They are Chinese and their English and resonses to Emails are terrible.

I am going to use these and supplement them with these 36 watters:

Cool!
Is there a White and a Blue LED in each fixture? Is each bulb 30w so 60 total?
Can't wait to see par numbers.
I was thinking of running the 16 of the 50w they have on my tank, but I'm really hesitant due to the lack of experience anyone has had with them.

How high are you going to mount those above the tank? I'm interested in what kind of spread you will get. I was looking at the these from the same site:

The only problem I see with these is there are no optics on them so you are getting a huge light spread from them. I wonder if you could take the glass cover off and put optics on them to concentrate the beam.

Ever since getting PAR38's, I've been experimenting with the making of a wall mount light fixture that projects over the tank. I could buy a ready made fixture that looks nicer, but...
I work with a CNC cutter, so I cut out some 1/4" ABS to use as a base. I used ceramic sockets from HD at $6 each, 2 packs of lock washers/nuts @ $1.25 each, a roll of speaker wire @ $10, some nuts and bolts- $3, 2) pvc pipe brackets @ $3, 3/4" pvc conduit box @ $6, a 3/4" sweep @ $2, 3/4" pvc pipe $2, Decora switch and switch plate $6, lamp plug $2.
Version 1 was made for 3) PAR38 bulbs and was somewhat crude.
Version 2 is currently in use with 4) P38's and an Ecoxotic stunner strip.
Version 3 will be similar to V2, but with a side and top cover to hide the majority of the wiring and sockets. The black wire will also be inside the tube. It will also use 1" pvc because 3/4" bows under the weight. Notice the 'safety' fish line attached to the ceiling. V2 doesn't need the safety line, but I sleep easier at night knowing it's attached. It does keep the fixture closer to level though.
Here's a pic with all of the lights on- The stunner strip actually balances the colors better.

I plan on mounting them 5-6" above the water line. The light spread with the 2 together is about as wide as one of my 175 watt MHs.

Each pendant has a 30 watt emitter(60 between the 2). I got one white and one blue, using the blue to balance out the white one.

i don't want to sound overly critical...casue I think it's great that they brought the colors back...But why is there so much hair algae? I looks like it's attached to the frags in the pics...I was just wondering if this was due to the lights...or if there is another explanation? It seems weird that the lights are great for saving the coral colors, but also casue algae to grow in excess.
I just want to clarify that.

Nice set up...
How is the color and intensity of the par38 vs the stunner strip? Both are similar in price, just one has 3 watt bulbs while the other has 1 watt bulbs.

Par38's will absolutely not cause algae without excess nutrients. I've had mine running for a couple of months and my rocks are solid purple.
BTW, there is a huge difference in PAR between the 1w and 3w leds. The color is nice, but unnatural IMO. That's why I'm supplementing mine with t5's, to round out the color spectrum.

Supplementing LED's with T5's is like copying the info from the computer screen onto paper by hand instead of using the 'print' button.
If you know how to mix and match white and blue LED's your colors should be similar to your T5's. After all, the pigments in the T5's are a mix of blue and white too. When I added the 453nm Panorama, it really toned down the royal blue Crees and made the overall effect more pleasing to the eye.
