You are misunderstanding - only 5 LEDs at a time will be on. That's why the discussion of cycling thru the 5 groups, and the 5 layers.5 x 20mA = 100mA max.
I've read of people lightly sanding them to diffuse them, dipping white paint, putting a white ping pong ball over them ...
i bought 10,000mcd LEDs because i figure i can always make them dimmer with code or resistors, but if i get like 1,500mcd LEDs i cannot make them brighter. CrossRoads also recommended high brightness LEDs. unfortunately they did not come diffused, so i plan on putting them in a drill and using that to sand them down. i know it will be a lot of work, but oh well. i wanted the higher brightness LEDs to be safe and not risk having a super dim cube.
