How to Use the Dim Factor Calculator

  1. Enter the candlepower (CP) of your light source in the first input field.
  2. Enter the distance (in feet) from the light source to the area where you want to measure the brightness in the second input field.
  3. Click the "Calculate" button to compute the dim factor.
  4. The result, which is the dim factor (DF), will be displayed in the result section.

Understanding the Dim Factor

The dim factor is a measure of how much the brightness of a light source decreases with distance. It is calculated using the formula:

DF = CP / (4π × Distance²)

This formula shows that the dim factor decreases with the square of the distance, meaning the brightness drops significantly as you move farther away from the light source.

Applications

The Dim Factor Calculator is useful for lighting design, stage lighting, and any application where understanding the spread and intensity of light over distance is important. By knowing the dim factor, you can better plan your lighting setup to achieve the desired brightness and ambiance.
