With the ”Quick-Click” system users can, within the General function set, choose full power (490 lumens to 323m), low power (up to 113 lumens), or Eco mode (a super power saving mode that yields up to 23 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 15 hours on high, 29 hours on low, and 112 hours on Eco. Water-resistant and drop-resistant.
