Lux to Lumens Calculator

Illuminance & Area

Understanding Lux to Lumens

To calculate the total luminous flux (Lumens) required to achieve a specific brightness (Lux), you must multiply the target Lux by the total room/surface Area.

This is commonly used in architectural lighting design to figure out how many light bulbs needed to properly illuminate a room!
