DIY Led - Linear Design

INTRODUCTION

For months now, I have been wanting, reading, planning to phase out my current T5 setup to LED. Right now I have 4x39 watt and 2x54 watt.
I believe, I have reach a point that Im going to make one for my 75 gallon tank. 48(W)x18(D)x18(H). I am not going to replace all my T5 all at once, but will be replacing them one strip at a time, thus going for this "linear" approach instead of the traditional square/rectangular heatsinks.
I will try to make it as simple as possible and as clear as possible so that people who also want to make one for their tanks can follow.
Disclaimer: This is my first LED build so I am in no way an expert. Everything I know are all based on previous builds I found on the internet.

Here are some of the references. If you are new and does not know anything about LED build but wanted to make one for yourself, then may I suggest to start reading....

CURRENT SETUP (November 2010)
This will serve as a baseline for our future comparison with LED.
75 gallon all glass - mixed reef tank, mostly softy and LPS and some SPS
4x39 watt Giesemann T5 (3 Blue+, 1 Fiji) mounted 6" above water line.
I came from 1x400 watt + VHO's, down to 2x250's and then to T5's, all because of wanting to save on some electricity.
