I received a couple of sets of pixels from Ray the other day. Each pixel is 5V, has a single 8mm LED and uses a 6803 IC. The colour order is RGB and they are really the same contents as a standard 6803 pixel, but in a flat based package with the input and output wires at opposite sides. The sealing around the wires seems better than a lot of the "single ended" pixels, but I haven't tried them for water resistance. I have added the wiring colours to the wiki.
