Our easy-to-use Lighting Calculator helps you determine the ideal amount of light for any room. Calculate the total lumens required and the number of fixtures needed based on room dimensions and desired brightness. Perfect for planning new installations or upgrading existing lighting!
Formula:
The Lighting Calculator uses the following steps to estimate your lighting requirements:
- 1. Room Area:
Area (sq ft) = Room Length (ft) × Room Width (ft) - 2. Total Lumens Required:
Total Lumens = Room Area (sq ft) × Desired Illuminance (foot-candles) - 3. Number of Fixtures:
Number of Fixtures = CEILING(Total Lumens Required / Lumens Per Fixture)
Where CEILING rounds up to the nearest whole number to ensure adequate lighting.
