David; The yellow-white LEDs we use are 3.3V 20mA (see specs here: http://ngineering.com/micro_yw_led_specs.htm). We also bought a LED tester that clips onto a 9V battery (http://ngineering.com/other_cool_tools.htm, #2 from the top) for testing the LEDs before installing them. When everything is in place, it will be powered by an 18V supply through a distribution board (http://ngineering.com/dist_board_layout.htm).
I'm a total novice when it comes to working with LEDs, but I'm reading and learning as we go
