Moonlight is the light that reaches Earth from the Moon, consisting mostly of sunlight, with some starlight and earthlight reflected from those portions of its surface which the Sun's light strikes. The intensity of moonlight varies greatly depending on the lunar cycle but even the full moon typically provides only about 0.2 lux illumination. When the moon is viewed at high altitude at tropical latitudes, the illuminance can reach 1 lux. The full moon is about 500,000 times fainter than the Sun. Source
