Understanding Lumens

Lumens are a measure of the total amount of visible light emitted by a light source. The higher the lumen rating, the brighter the light. This calculator helps you determine the appropriate brightness level for your room based on its size and your personal needs.

Additional Tips

  • Consider the type of activities you will be doing in the room when determining the desired lumens per square foot.
  • Don't forget to account for any existing light sources in the room when calculating the total lumens needed.
  • You can use this calculator to estimate the lumens needed for multiple rooms and then add them together to get the total lumens required for your entire space.
