Here are some pictures of my lighting setup with the replacement LEDs and the 10w power compact.
In the filter picture below, you can see how I zip tied the electrical cord to the lighting arm. You can also see that I've crammed a thermometer in one of the HOB filters as well as my Hydor heater. I am thinking about putting my CO2 line in a hole that is near the impeller as suggested on this forum. The less equipment inside this tank, the better.
Below is a profile picture of the lighting unit. The cord that I run the power compact has an on off switch...kind of helpful. You can see it towards the bottom left of the small photo,
