Change Log[]

Patch 1.8.3[]

  • Quality of Life: adjusted and simplified the TIR Optic description.


  • The abbreviation TIR stands for "Total Internal Reflection", describing the effect of completely reflecting a light ray reaching an interface with a less dense medium when the angle of incidence exceeds a critical angle.

TIR lenses are often used in LED flashlights due to their excellent ability to extract and control all the light produced by LEDs, far superior to older types of reflector lenses.

  • Increases the Beam brightness by 30 %.
  • Increases the Blindness duration by 15 %.
