Measuring LED Light Brightness: A Practical Garage Guide

Quick answer: Measure LED brightness by separating lumens from lux. Lumens describe how much total light a lamp produces. Lux describes how much light actually reaches your workbench, floor, or wall. For garage planning, use lumens to compare products, then use a lux meter or phone app as a rough layout check after installation.
