Say no to Disco!
One of the problems with LED fixtures is the farther the LEDs are from each other, the more Disco effect you will see. This is the effect of the different LEDs not mixing their color properly. With this 3-up CREE star you can say NO to Disco because the LEDs are so close together.
- No more trying to figure out the pattern
- No more disco
- No more guessing how many of each LED you need
Its all done for you
These stars also come with two solder pads per LED so you can put each LED on a different driver if you want or solderblob them together.
Just spread these stars evenly across your heatsink for the perfect color blending
- 2x XTE Royal 1x XTE Neutral
- The best combination of CREE colors to get the correct blend needed to give you a nice 14K look on your reef. This 3-up star combines 1 XT-G Neutral White with 2 XT-E Royal Blue 455nm.
For wiring of the 3UPs please check picture 7 and 8 (press the > arrow) on this product page
Custom optics are available in 40 degrees that easily slide into the holes on the star.

Dense LED configurations :-)
by Wes T – 22nd May 2013
There is a whole new movement in the DIY community for this LED Cannon style LED setup. That is a high capacity, high density led cluster instead of the even and spread out LED configurations of the past. Interesting concepts, that are hard to manage with 1 LED per Star configurations.
I am only using 4 of these LED stars now on my 12 gallon, and it is MORE than enough for my softies. It is running now around 70% and thats about all i'm going to push it. I am using all "makers" hardware and controllers, and everything is cool to the touch.
My expectations weren't met as far as brightness, but i soon found out it was enough for my needs. These are not XMLs, so be sure to set your expectations correctly on how bright these will be.
However, the "shimmer" from these LEDs are amazing, and my tank has come alive. Even my fish seem to have more pep in their step.
Also, remember you can "bridge" the pads for the blues with a glob of solder, and you don't have to individually wire them. You probably could "blob" them all together for one controller if you were so inclined... but i wouldn't recommend it. Be sure to use a "fine" tipped soldering iron, as mentioned before these pads are small!

Ok for specific applactaions
by Joel Espinoza – 23rd Apr 2012
These have some upsides and downsides vs individual LEDs:
Upsides:
No disco effect
VERY little spotlighting (even with 40 degree optics I run these these 5" over my waterline)
Easier to attach to heatsink
Easier to plan LED pattern
Downsides:
Much more difficult to solder (6 tiny pads to solder instead of 2 large ones)
More heat per surface area (3 LEDs on the same size star as 1 LED)
They can not be driven as hard (heat compacity limited, even with a good heatsink)
Limited optics (currently 40 degree only)
So in the end just be sure what you are getting into, in some applications these can be great, in others single stars are better.
If you are not really comfortable soldering, do not order these.
