Calculation Formula

Lumens per foot = Total Lumens ÷ Length (feet)

Where:
- Total Lumens: The total amount of light output from the fixture
- Length: The length of the area to be illuminated in feet

Learn how to use the Lumens per foot calculator calculator and its working principles

How to use the calculator

  1. Enter the total lumens output of your lighting fixture in the "Total Lumens" field.
  2. Enter the length of the area to be illuminated in feet in the "Length" field.
  3. Click the "Calculate" button to compute the lumens per foot.
  4. The result will be displayed in the "Lumens per foot" field.

Principle explanation

The lumens per foot calculation helps you determine the lighting density of a space. This is particularly useful for:

  • Designing residential lighting plans
  • Commercial lighting installations
  • Ensuring adequate lighting for specific tasks
  • Comparing different lighting fixtures

Example usage

For example, if you have a LED strip that produces 600 lumens and you want to illuminate a 10-foot hallway, the calculation would be:

Lumens per foot = 600 lm ÷ 10 ft = 60 lm/ft

This means the hallway will have an average illumination of 60 lumens per foot.

Applications

This calculator is particularly useful in:

  • Home renovation projects
  • Office lighting planning
  • Retail space illumination
  • Agricultural lighting systems
