I like the moonlight mode on my Quarks. I use it when I don't want to destroy night vision, and when I don't want to be dazzled with dark adapted eyes.
When I want to read at close distance it's great. Also when I don't want to draw attention.
Actually - believe it or not - sometimes I had wished an even lower low mode than 0,2lumens. When I was on a starparty some month ago I tried to see in the darkness among amateur astronomers with their telescopes. But the moonmode felt actually too bright in that case to not disturb.
0,2 lumens may be a low brightness, but makes it possible to see and locate at least 10 meters distance in total darkness. That does mean 0,02lumens would be more than adequate to read a note in the hand.
When I in this moment hold my Quark and shine against my eye at ca 20cm distance it's actually a bit dazzling. And now it's daylight.
It's all about purpose and distance.
