|Here is some company information regarding the HP21, which is now regulated
The HP21 is the ultimate High Performance LED Flashlight from Coast. With major improvements over other high output handheld flashlights, the HP21 is the choice when only the best and brightest flashlight will do. A quick cycle switch allows you to select between a high output setting of 1317 lumens, a high powered strobe mode, or a low output of 207 lumens. Coast's Pure Beam Focusing Optic System with Speed Focus Control provides superior beam consistency from spot to flood, with no dark rings typically associated with focusing flashlights. A rubber bezel ring is added to increase the ease of focusing the beam. The Bulls Eye spot beam pattern gives you a great focused spot with a maximum beam distance of 260 meters (852 feet), while producing an outer ring of flood light which allows you to see a broader area to the sides. Built tough, an impact-resistant, lightweight aluminum casing resists rust and corrosion. Tested and rated to ANSI/FL1 standards, the HP21 also features unbreakable LED's and rubberized O-ring for reliable water resistance and durability. Backed by Coast's lifetime guarantee against defects in materials and workmanship.
Tested and rated to ANSI/FL1 standards by an independent laboratory. ANSI FL1 flashlight standards explained.
