I decided to try go above and beyond with these lights and try produce something professional. 
It all started here, with this first version:

This is where I first started playing with 3D design.  I went and got it all 3d printed and we ended up with V1:

The colours were good, the light was bright and everything remained nice and cool. This light is over my tank today and has grown plants really nicely. 
However, I discovered a few issues:
a) Not great ventilation. The small air ducts annoyingly creates a wooshing noise from the fan which is otherwise silent. 
B) I printed in PLA - This is fine if the fan never fails, however I accidentally unplugged it once. The enclosure basically melted. 
c) The mounting system isn't great - I didn't think about how I was going to mount it when I designed the enclosure and so I had to improvise. The way I ended up mounting it works, but isn't that great.
d) The internal wiring is a mess. 2 channels have recently failed probably partially due to this. 
So keeping these issues in mind I have redesigned the entire light - This time using my own aluminium MCPCB's with custom made drivers and even a wifi card add on if I want that (in future), an open heatsink and a tank mounting design. It is way more compact due to the PCB and a thinner heatsink I can use due to the better ventilation.
Here are some Fusion screengrabs:

I'm sending the PCB's off to be made and assembled pretty soon, as soon as the manufacturers get back to me. Once I recieve those I'll be sending off the 3d files for the enclosure and mounting parts to be printed, likely in ABS this time.
More updates then ;)

10x of my PCB’s arrived today and will hopefully be getting one built within the next month.
<90CRI, 100 watts, 4 channels of white, red, green and blue to control using an inbuilt wifi controller. Sits perfectly on the fan cooler.
