Why do ECE, DOT, ADR, GB Measure Light intensity By Lux Unit? – Automotive LED Lighting Technology Information |...

Whatever on ECE, DOT, ADR, or GB regulation, the light intensity is measured by lux. The lux (symbol: lx) is the SI derived unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square meter. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.
