Minor amounts of non useable light like moonlight won’t hurt a thing. A major source of light close enough that any real intensity is hitting the plants will stress them or even prevent or stop flower production.
tell him to go with only 8 hours of darkness and start a journal here.
Not sure what your point is with this post? Yes the moon REFLECTS some of the suns light and can be rather bright when its near full. However it doesn't provide useable light for photosynthesis from anything I've ever seen or read. Thus why plants still flower outdoors even with moon light, and why plants in parks still flower inspite of distant street lights. If you get those street lights too close though they will mess up your plants. Thankfully the moon doesn't stay full or move any closer so we don't have to worry about it.

Moonlight yes, if you've ever looked at a star through a telescope it's just a perfect circle
I would err on the side of caution with that one.....
