Compared with sunlight, the wavelength of full moonlight is generally centered around 400 nm (580 nm for the sun) with a very low energy level (0.2 lx or 0.0024 μmol m− 2 s− 1). The red:far red (R:FR) ratio of sunlight during the day is more than 1.2, while that of moonlight is between 0.18 and 0.22

Intensity (in lumens) is also hugely different (0.09 vs 3,955). Over a 40,000:1 ratio!
