- Where D is the Optical Distance (m)
- Q is the quantity of light emitted (lumens)
- E is the light intensity (lumen/m2)
The calculator will evaluate and display the value of Optical Distance, also known as Lumens Distance, by entering the quantity of light emitted (lumens) and the light intensity (lumen/m2) into the Optical Distance Calculator.
