Basically I pulled out all the wiring in the original top that I did not need. The only thing you need is the that powers the Night leds and the fans and one of the relays. The rest you can just get rid of.
After that I connected all the new LED drivers as stated by the manufacturer. Each driver can drive up to 20 LEDs. All the whites (10000 k and 6500 k) is on two drivers - all the blue are divided on 2 drivers and all the exotic (15) are on the last driver.
The drivers were all connected into one wire and connected to the relay - so it is powered by the original timer. JOB DONE! Now we have light!
The heatsinks was predrilled - so it was just a matter of drilling holes in the old t5 reflector and bolting it on.
The white wires is to the potentiometeres so you can control how much light you want on the string. I just clipped out one of the pins in the fans guards an put them trough there as you can see in the pictures
The heatsinks get very hot - so you need the fans!
It was actually build by me and a friend of mine. I did all the 230 v electric work and he did all the work of getting the LED position right and putting them on with wire
