The brightness you see versus the brightness you read about: on light levels, LEDs, and the shortcomings of the lumen

The brightness you see versus the brightness you read about: on light levels, LEDs, and the shortcomings of the lumen

The industry uses a measure called the "lumen" to measure light volume across light sources. Based on our installations, we believe the better quality the light, the "brighter" a lumen appears. Here we'll explore why we think the lumen fails to indicate brightness properly where LEDs are concerned and what we do about it.
