Not that I'm aware of - and definitely not a fixed mode light with a mechanical clicky. A real momentary allows you flash the same mode repeatedly with half presses, or as long as it is depressed. A multi-mode changes modes with half presses. There is no way I am aware of that a light tell the difference. That said, one could argue that a Peak QTC light with momentary switch can do both - it is momentary and the further the button is depressed, the more light you get.
