The Beam Calculator helps you set up your profile fixture by determining the following:
  • Beam Spread - The degree of lens you should use
  • Beam Diameter - The size of the circle of light
  • Throw Distance - The distance between the fixture and the surface
To use the calculator, input two of the known values and then click Submit. The third value will be displayed.





When calculating the Beam Spread, the resulting degree may not be available in a lens tube. For the best results, we recommend using the closest available size.
Purchase a lens tube here. Please call (312) 332-5611 if you have any questions.
