Gone is the ability to flip a fresnel lens over the beam to diffuse it optically. Instead, a default lens provides a high beam center with a wide spillover. You can select a reactive setting where the intensity of light reflected back is sensed and the output adjusted on the fly to approximate a constant level of illumination. Thus, if you’re in tight quarters aimed at a white wall, the light will dim, down to 7 lumens if you’re close and the white wall is actually a mirror. When you point away, where the closest surface is yards away, or a darker surface, the light intensity will increase, depending on the mode it is in, up to 120 lumens. It’s cool bit of technology but frankly my brain makes those adaptions faster and if I need more or less light I’d rather make the switch manually. YMMV.
