Solar light on Pluto

Folks

Reading through various articles about the upcoming launch of the New
Horizon probe I did not manage to locate any solid information about
the amount of energy & light available from the Sun on Pluto.

I remember having read something like "about the size and brightness
of Venus as seen from earth".

If it's true I find it really remarkable that an earth based
telescope would manage to "see" Pluto...
