LED for planted ADA 60-P. Help !!
 

So finally I've decided what tank I want. It's a 60-P. 24x12x14 (lxbxh).
Now I want to make a LED with makersLED heatsink.
Here's what I've got after reading as much as I could-

1 Heatsink- I want to use MakersLED heatsink but dont know what length to order !!
2 LEDs- XM-L or XP-G I can use any of these. But how many to use!! And do I need to mix some other color LED also ?? I'd be keeping a lot of red plants in my tank.
3 Dimmer- For dimming purpose I've chosen this- LED GB Dimmer. Comment please...
4 What driver to use !! I could have calculated the total wattage and the current but I dont know how many LEDs to use.
5 I've seen fans on every makersLED kit. What fans are they ?
6 Any link on making such project would be really helpful.

Sumer.

I tried Hoppy's LED calculator but couldn't find the value of tan^2 10. I should have studied math in my school days.. sob sob.

Thank you O2surplus.
I should've looked into sticky first. My bad.

Here's my journal, I did it for a 60h. Same footprint
