And, there are "low current" LEDs that gives aprox the same
amount of light @ 1mA as a "standard" LED @ 10mA. But note
that the *max* current in these are sometimes as low as 2 mA with
7mA as a more common value.

Cost a little more, of corse, if they didn't there would not be any
"standard" LEDs probably :-) :-)

Still, powering a LED based clock (even using low current LEDs)
with the LEDs constanly "on", is probably not a clever idea...
