JBJ 12Gallons nano LED upgrade question?

Some question for you guys ... I have an extra JBJ 12Gallons DX nano tank that I like to setup. It have 2 PC light right now and I would like to do LED upgrade. Now I have 65Gallons tank that have 36LED from RapidLED DIY kit. (Very happy with it BTW)

Wondering how much/many LED do I need and what size of heat sink for this 12G tank? like to try some SPS in this one. Also like to have it dim able.

Any thread on 12Gallons build link would appreciated!
Thanks

 

I came across this today and it looks to be an easy install. I know nothing about it other than the website and very brief email's back and forth with Steve. I'd very much like to try it but I'm waiting for some $$.

i think JBJ is similar to biocube, maybe you can try something like this. This is one of my client's mod with the nano LED from Zetlight.
Not saying you have to get the same light, just an example wat u can do. Yo also can try to DYI all the LED with heat sink onto the hood, the only thing is for me I can't find a proper way to mount it inside the hood as I am not that handy.

and here is how his tank looks like
