The visibility of flicker on moon isn’t very objectionable. My testing shows it occurring at ~2kHz so it will probably not bother most people. Especially if you don’t stare at the light from distance or the light doesn’t have a chance of reflecting from shiny objects. It will not be visible if you just aim it at the ground no matter how rapidly you move your eyes. The snob index of 11% means that it’ll probably be fine unless you’re, well, a snob. The fact that it only happens on the lowest of modes, makes it even less visible. The HCRI model has more severe shortcomings than the slight flicker though.
