My actual preference is M-L-H, but it was not listed, so I chose the one closest to my needs/usage.
If it is a fixed changeable setup I prefer it start on low like my automobile where I can add more if needed. How low? Well generally enough to be useable in most situations. Say 10-20 lumens.
I grew up with light bulb'd flashlights that were generally putting less than 20 lumens. So I find around 20 to be adequate pretty often.
I can definitely see the virtues of a rotary system and have some rotary lights like lanterns and headlamps. Yet they are set to come on at about the same output as a 2 cell bulbed light.
My 2200 lumen Streamlight starts at 60 lumens and rarely goes to the medium 600 or 2200 high. But boy is it nice to be able to sometimes.
