Hmmm, that is probably why Kessil, AI, Radion and others have bunched 3W LED's together in Pucks.

Yeah that's one row of LEDs !! Mine is 5 rows of 22 LEDs !!!

The Hamilton fixture over this tank, a straight line of 3W LED's, each about 1" apart, produces this shimmer. http://www.hamiltontechnology.com/item/3-Watt-Kona-Sun-Extreme-Bright-LED-Lights-2239

Yes, keeping them closer together will produce more shimmer than if they are spread out then each one produces a different shadow. Those shadows cast in a different locations and cause a larger shadow area which cancels out the skimmer. Single source light (I.E. hallides) produce the most shimmer as every ripple on the water surface produces a matching shadow that moves on the sand without any other shadow interfering with it.

Ok thanks guys !! I'm also thinkin of another project,, it would be more for shimmer,, I getting upset my led fixtures doesn't shimmer like the radions (cuz they aren't radions I know I know) however I'm wondering if I layout my LEDs like the radion pucks are laid out maybe I'll get more shimmer ,, instead of being in straight lines 11 across by 5 tall,, ya no ?? Anyone have any knowledge of this ? ]]> Mon, 21 Mar 2016 15:42:30 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=79508&PID=609945&title=diy-led-refugium-light#609945 <![CDATA[Diy led refugium light : Looks like a fun project.

Looks like a fun project. If I had that stuff laying around I too would choose it over the economical "Home Depot Special" I usually use for the Refugium light.

Have fun and Aloha,

Run 6 in series on one string and 7 in series on another. Connect the two sting in parallel. That divides the current (amps) (I) in 2. I'd put a standard (not slow blow) fuse in the circuit in case one string goes out, that way it won't fry all of them.]]> Mon, 21 Mar 2016 00:30:04 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=79508&PID=609907&title=diy-led-refugium-light#609907 <![CDATA[Diy led refugium light : Wait another question guys !

Wait another question guys ! So the forward voltage of these LEDs are 350mA,, so in order to use a HDD driver of 700mA I would need to do two strings of LEDs so one of six and one of 7 ,, on that same driver ?? Or am I missing some thing ? ]]> Sun, 20 Mar 2016 21:26:00 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=79508&PID=609902&title=diy-led-refugium-light#609902 <![CDATA[Diy led refugium light : Thanks you guys so much !!

What fatman said but it's getting really hard to find non switching ones anymore. I don't think it's even $2 more for switching. More like .50
