High-Reliability Electronic Switch With QuickClik® User Interface The QuickClik® user interface, already familiar to anyone who knows our product line, is what gives the ML150LRS™ flashlight its extreme versatility. It enables each user to custom-configure the flashlight to optimize ease of access to the functions he or she needs most. Five separate functions are available – High Power, Low Power, Eco Mode®, Strobe (12 Hz) and Momentary (“Dead-Man Switch”) mode. These are organized into four different function sets – General, Outdoor, Law Enforcement and Military. So, for example, if a user selects the “General” function set, three of the five functions are accessible: High Power (with one click), Low Power (two clicks), and Eco Mode® (three clicks). If a user invokes the “Law Enforcement” function set, a different set of three functions, in a different order, becomes accessible: Momentary (with one click), Full Power (two clicks), and Eco Mode® (three clicks). In the “Outdoor” and “Military” function sets, the Strobe function is one of the accessible functions.
