8:1 multiplex requires 8 times the peak current to get the same average
power. Years ago I saw some claims that with multiplexing you can use
lower average power for the same perceptual brightness, due to retinal
persistence. However, I've seen other people claim that this is not
true. It would be entertaining to set up a double-blind test and find out.
