Turns out that these little emitter doo-dads (LEDs) really are tiny. See the bottom of page 1 at: cree.com 200x200 microns, which means you can get ~40 on the edge of a square centimeter (rounding to 250 microns for cutting waste, that's 4 in a millimeter X 10mm per cm). A square cm being square, that's 40x40 or 1600. Then a 2" diameter wafer has a radius of 1", or ~2.54cm, and so pi * radius squared gives us ~20 cm square. 20 * 1600 = 32,000 and with some waste due to the roundness of the wafers, we round off to the previously stated "30k per wafer".
