	500 UV LEDs are currently on a boat from China towards the space. This should be enough for at least 1 decent size box and a tanning bed.		500 UV LEDs are currently on a boat from China towards the space. This should be enough for at least 1 decent size box and a tanning bed.

			Update June 2013: Almost finished soldering the boards. Each 10x16 prototype board contains 12 x 18 = 216 LEDs, and the enclosure will house 2 boards with 432 LEDs in total in a 20 x 16 configuration. For each 3 LEDs (in series) there is a single 68Ohm resistor. Total amperage per board is around 1.4A (observed).
