DIY LED Using 10 Watt Arrays

[chewie]

Very informative read. I am in the process of trying to figure out how to do a build myself, following along this thread to see how it is done.

Here is a list of parts I am thinking of using:

Dimmer. ( may have a few to run different led temps, blue, daylight 12000k etc...)

Daylight 12000k

Blue light

OR

Power supply ( once again a few to run different lights on timer. Not sure if this will work or if I need an actually LED driver supply. )

or if I need a proper led driver

any suggestions?
