This article explains the difference between lux and lumens, two units of measurement used for measuring light. Lux is used to measuring the amount of light output in a given area, while lumens indicate the total amount of light emitted by the light source. The article examines why most LED light manufacturers label their products by lumens and how some may not accurately define the luminous parameters of their LED lights. For headlights, Lux is a more accurate measure of how well they illuminate the road. The article provides a test procedure to measure lux by installing the bulb inside a housing and testing how well the lumen amounts are projected or reflected out from the housing.
