Which unit is most suitable in comparing needed light intensity for night reading on the Moon, vs on Earth? Which unit is best to use, and why, when determining how many times easier it is to read a newspaper (or any other printed text) on the moons surface at night under a full earth, compared with reading it outdoors on  earth during a cloudless full moon night: Albedo, Bond Albedo, Apparent Brightness, Apparent Magnitude, Geometric Albedo, Lux, or something else?
Readability requires taking into account the sensitivity of the human eye to various wavelength. This is called Illuminance.
Physics knows Lumen (flux weighed by human perceptibility) and Lux (flux per unit area weighed by human perceptibility).
Quoting that, different light sources have roughly these values:
Source             Lux
Full daylight   10,000
Overcast day     1,000
Very dark day      100
Twilight            10
Deep twilight        1
Full moon            0.1
Quarter moon         0.01
Starlight            0.001
