I am trying to determine the lunar surface near or far side daytime illumination levels in Lux or foot-candles but there seems to be no directly measured values available. I did find this information on the levels as measured from earth, so it should be possible to work backwards to arrive at those values I presume. My math is very rusty indeed though, so thought I'd put the question to some experts. How bright is moonlight? https://academic.oup.com/astrogeo/article/58/1/1.31/2938119
Illumination of the moon's surface at night in full earth is 15-17lx

The camera was equipped with an automatic sensitivity adjustment system, which ensured the transmission of high-quality images in the illumination range from 80 to 150,000 lux.
