Light Reading Dimming: Perceived Value vs Measured Value

December 11, 2014

Although many LED lights offer a dimmable range, (such as 100% to 0%) there is a difference between the measured value of light and the perceived value of light.

For instance, an LED light that is dimmed to a measured value of 10% will be perceived by the human eye as a value of 31%. This difference is important to keep in mind when buying and specifying LED lights and dimmers.
