Hello Boki,
How did you do that test?
Many people's eyes perceive "super red" as the most bright for a given
current. But that can be different, depending on your age (no, you don't
have to tell us...), degree of color blindness, contaminants such as
water vapor (fog) in the path and so on.
Well, how bright is bright? It might be interesting to set up a little
jig, with a red and a green (and maybe others) LED, where each one has
a pot, with a knob. You tell your victims^H^H^H^H^H^H^Htest subjects to
adjust them until they're "equally bright", then take a photometer of
some kind, and your trusty DVM, and log what the currents and PHM
readings are.
Write that up properly, and you could probably get federal funding. ;-)
Cheers!
Rich
