With the ''Quick-Click'' system users can, within the General function set, choose full power (487 lumens to 323m), low power (up to 143 lumens), or Eco mode (a super power saving mode that yields up to 58 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 1/4 turn of the head. Run times are 6 hours 30 minutes on high, 101 hours on low, and 260 hours on Eco. Water-resistant and drop-resistant.
