I have one other use for moonlight mode I haven't seen mentioned: I use it to spot the reflective eyes of animals at night. This lights up animals even better than higher modes, because moonlight doesn't cause their pupils to constrict. Thus, you get wide eyes which reflect back a lot of light. You won't see anything else of them... just their eyes, but they will be bright!
To do this, hold the flashlight up to your forehead or between your eyes, and shine it toward the woods or wherever you are looking. You need to hold the flashlight as close to your eyes as possible, because the light will reflect directly back from the animal's eyes. You'll see it best when that light is reflected directly back at your own eyes.
You can see glowing eyes a long way away.
