    Very nice! Where would you get those LED's I am not that great with electronics so how would i determine what power these need and the resistors needed.

    Thanks!

    Where can we find this LED calculator? Also, how do we make daylight (5000K + brightness) led lights?

    I havent done the thing but im sure the paste is Epoxy glue, or A B glue, you must mix the two then use as normal glue, super hard.
    I also use glue gun to glue my LED, no problem so far friend!
