- Data Specifications
Lux meters measure illuminance, a measure of the brightness of light projected onto a flat object (unit: lux, or lx). JIS and other standards define how illuminance must be measured depending on the activity performed in the illuminated location and the characteristics of that location. For example, the Fire Service Act requires that the illuminance of emergency exit and evacuation signage fall within defined standards, and lux meters are used to verify compliance.
