My cree led build.(Updated LED pics 4/30/13 pg 8)

The dimmer box is just a radio shack plastic project box(they come in different sizes).
I'm using 16 gauge because that's what I had laying around from other hobbies..

 

Should be..I wrote to cree before the purchase explained what I had tank and live stock,and this what they sugested..I could always add more down the line..maybe some warm whites for little more punch/lower kelvin..

 

I guess I'll stick with 48 as well, then.

 

Congrats on the progress.

I'm guessing 80deg will suit you well. 60s will be fine if you're hanging them pretty higher over the tank, around 18-20".

14 is pretty big and probably way overkill. I used 18 on all my stuff; RapidLED sells 20 gauge on their site.

48 should be plenty for him. I'm using 60 on a 5' tank (~120 gallons).
72 is way overkill on a 75.

 

Will 48 be enough to support SPS?

 

Absolutely. Evolved is using 60 on his 120 gallon with tons of SPS. I have a 16 LED setup (8 White XP-G with 65* optics, 8 Blue XR-E with 80* optics) on my 29 gallon growing SPS. I recently added 8 more LEDs, but all in actinic supplementation for my personal color preference. 72 LEDs would be way to much! 3 watts doesn't sound like much, but these LEDs are BRIGHT!

 

@ evolved
Yea it will prob be around that 18" mark above the tank..but ill keep the 80* in mind.


Also what MA do you guys run your leds at..I purchased the ultra premium kit..right now they are set for whites 850 ma and blues at 700 ma...

 

I have no idea what specific current value I run mine at. The XR-E dimmer is set to max at 950mA, and the XP-G dimmer is set to max at 1.45A. I probably run the blues (XR-Es) at ~850, and the whites (XP-Gs) at ~1.25A, but those are guesstimates based on the positions of the dimmer knobs.

 

Nice looking build.

And man do I wish there were about 50 more threads like this one to read through

 

There are actually quite a few.
