Uh, one phrase for ya: Do NOT buy it... You'll be sorely disappointed by its beam shape and performance. The Vector R2D2 easily beats it. Any 2MCP (Optronics or Brinkmann or LSI) easily beats the Blue Eyes 2MCP... And no, it does NOT reduce glare... I still get the same glare problems shining it out of a window. And the beam is so blued and distorted by the plastic eye-coating on the lens that it is actually irritating...
