ASP flashlights are designed to professional law enforcement standards. They have gained a worldwide reputation for performance. The Triad is the first of a new generation of high intensity LED lights from ASP. Each Triad is precision machined from high strength aerospace aluminum. A satin black hardcoat finish is accented by an extremely durable foamed vinyl grip. Two leak proof Lithium power cells provide 2-hours of continuous run time with a ten year shelf life. Auxiliary cell tubes may be interchanged to provide 3-hours (3 cells) or 4-hours (4 cells) of illumination. The smart chip technology of the Triad automatically recognizes each battery tube and adjusts its driver to compensate for any increase or decrease in voltage. The light maintains a consistently brilliant beam. The Triad employs three independent parabolic reflecting chambers which are metalized and gasket sealed. It produces a brilliant white light. The pattern geometry provides both a room illuminating halo and a penetrating central beam of incredible brilliance. The SoftouchA(R) Activation System of the Triad is sensitive and quiet. The rear mounted switch provides universal orientation when grasping the light. The overmolded activation button is always under the thumb. The three position rotary collar is positive and direct. In the centermost position, the switch is locked off. The collar is rotated to the right for constant-on. To the left for intermittent light. Each Triad combines the innovative design and unparalleled manufacturing expertise of ASP. O-ring sealed for water resistance. Performance tested under the most severe conditions. The Triad is unmatched in function and durability. Background Designed to professional law enforcement standards. Aerospace aluminum construction. Precision machined, No sharp edges.
