" From: velociraptor <velociraptor at gmail.com>
" Also, from what I have read, the eyes respond to brightness along a
" logarithmic scale.  So, at a certain point, increasing *perceived*
" brightness takes so much power and/or LEDs to increase the eyes
" perception that it becomes economically unfeasible given present LED
" technology (but it's certainly a moving target given rapid LED
" advances).

you could also play perceptual tricks.  if the leds were pulsed at say
1KHz with say a 1% duty cycle, they could take a -lot- of current
which would result in greatly increased apparent brightness, and
flicker would be a non-issue.
