And CR are part of the Duty Series of ASP illumination tools. They have an aluminum frame and foam grip. A clip groove is machined into the lens and switch end of each light. A replaceable Snap-Loc™ Clip snaps into either groove. Lights are available with a Black, Coyote or Neon Yellow body. Poly Triads are ideal in cold weather. Their polymer surface is more comfortable in the hand under adverse climate conditions. Poly Triad lights are available in both AA and CR123A configurations. AA lights use a battery that is readily available worldwide. However, they sacrifice power. CR lights have a greater output. However, their battery availability is less common. The internal frame and parabolic reflector of each Poly Triad is aluminum. This alloy core improves conductivity and manages heat. Poly Triad lights are compatible with the entire Triad line of performance products. Auxiliary TLC belt cases, Lithium power cells, Link™ battery holders and zippered storage carriers are available. The lights are strong, lightweight and brilliant. Polymer illumination tools, built to the quality standard of ASP.
