Above referring to pulsing the LEDs with square wave circuitry, to make
the appear brighter to the brain. This is obsolete by now, and may give
you RF interference. For panel indicators, you can get super brights
cheaply now that will put spots on the retina, requiring cutting back
the current or buying fewer millicandles. Diffused clear LEDs to me are
the most attention getting.
For area illumination as you described, the realities of viewing angle
(i.e., beam width) similarly means multiple very super brights, so
adding extra(s) makes up for not having the pulse enhancement.
