What is Lumens Per Foot?

Lumens per foot is a measure of the light output per unit length of a light source. It is commonly used to compare the brightness of different lighting fixtures or to determine the appropriate lighting level for a space. This measurement is particularly useful for linear lighting installations such as LED strips or fluorescent tubes.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Lumens Per Foot (LPF):

LPF=TLL=100010=100 lm/ft

The Lumens Per Foot (LPF) is 100 lm/ft.
