Too tedious and too numerous to mention.
When you have a tool you use it, when you're without you do without.
I use high setting for seconds at a time on any given day to get a better look at something, I use moonlight and low several times a night to find something in the shadows quickly, I use a long running medium mode occasionally to help me take care of an involved problem of unknown duration.
I switch and charge batteries every few weeks or so whether I need to or not.
