Default Continued...

So, once the mounting portion is complete, it is time to start wiring things up. There are videos on youtube explaining how to use artic silver for the LEDS, and also tips for soldering LEDS. I highly recommend watching these! For those paying attention, I did wire up the two moonlights incorrectly here. I was in a soldering trance and just kept connecting things together! I did remove one of the wires when only one LED came on... In the last two pics, you can see the 2.2K resistor wired in series with the 10K pot. Since I had an extra 12V power supply lying around, I used a simple voltage divider to get my 10V. Unfortunately, my cheapie PS is non regulated and I get 10.5V when the pot is at 10K... This is remedied by turning down the pot a quarter turn from full on.

Here you can see the wires being routed inside the arm, with the top cover taken off. I also had to cut an opening for the wires to escape out of the arm at the bottom, which you can see in the last pic.

After hooking up the lights and testing, I decided there was too much shadow in the front corners, and that I had mounted the light too high in the neck of the aquarium. So, off to Lowes, and I found some ErecterSet looking pieces in the hardware isle. Two holes were enough to get the light down into the neck and not above it, so I cut it down with the dremel.

Before... Notice how high up it is? Above the rim.

After lowering it with the hole-y piece. Notice it's IN the neck now, eliminating most of the shadowy corners.
