DIY LED Build questions

[racer_X_123]

I want to build my own LED setup but I dont really know what kind of LEDs I should get (what color?) and what not. I have the integration knowledge and the fabrication skills needed but I dont understand all the lingo when I search for what parts I need.

 

Is there a thread or list of threads that is like an end all on DIY LED build?

 

Thanks!
