With the familiar "QuickClik" system users can, within the "General" function set, choose Full Power (maximum Lumens): Low Power (up to 120 Lumens: 2-Cell / 3-Cell); or Eco Mode - a super power saving mode that yields up to 25 Lumens with greatly extended run-time. There are three additional function sets - Outdoor; Law Enforcement; and Military - each offering a different set of functions invoked in a different sequence, for quickest access to the functions the particular user prefers. The IMPROVED, faster handling focus system now adjusts from spot to flood with less than turn of the head.
