How to Calculate ‘n light’
Introduction & Importance
Calculating ‘n light’ is crucial in lighting design and engineering. It helps determine the amount of light needed to illuminate a space effectively…
How to Use This Calculator
- Enter the distance from the light source to the work plane.
- Enter the desired illuminance level.
- Click ‘Calculate’.
Formula & Methodology
The formula for calculating ‘n light’ is:
n = (E * d^2) / (L * π)
Where:
- n is the ‘n light’
- E is the illuminance (lx)
- d is the distance from the light source to the work plane (m)
- L is the luminous flux of the light source (lm)
