The intensity of moonlight
varies greatly depending on the lunar cycle but even the full moon typically
provides only about 0.1 lux illumination.
When the moon is viewed at high altitude at
tropical latitudes, the illuminance can reach 0.26 lux. The
full moon is about 1,000,000 times fainter than the Sun. The color of moonlight,
particularly near full moon, appears bluish to the human eye compared to most
artificial light sources. Source
