To do this there are three lighting modes for each of which the user can select the power from among ten possible levels, from 8 to 140 lumens. Also features a boost mode (160 lumens), a flashing mode that can be programmed & a wide angled lens that offers the option of switching instantly from a focused to a wide flood beam
