An ultrabright LED can be run off much less than 1mA with decent light

Certainly so, got a bit of kit with a blindingly bright blue LED on
the front. It lit the room up at night! Hacked into the wiring to add
a series resistor, the thing would glow with the leakage through my
dry fingers from the 3v supply. IIRC it now taking 60uA and is still
too bright...
