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!

The leds are 1w each and i have buy from ebay,1w leds work on 3.3v and pull about 300mah current,on google there is led calculator for single and serial schematic.

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!
