CIE 2025 proved to be a milestone for integrating developments of the past years and setting the groundwork for the continued global leadership role of the CIE. The event was a resounding success, with 430 persons from 40 countries or territories attending the scientific conference (which saw 87 oral presentations and 168 poster presentations that all underwent a doubleblind scientific review) and 310 persons (of whom 240 were on-site) participating in the CIE’s Division and Technical Committee (TC) Meetings program where the current and future scientific work of the CIE was discussed. The unique role of the CIE attracts a varied audience – a mixture of experts from academia, industry, national metrology institutes, standardization bodies, Masters and PhD students as well as architects, lighting designers, engineers and lighting practitioners, and governmental and policyrepresentatives. This diverse audience also makes it attractive for sponsors and exhibitors, with a wide variety of innovative products and equipment on display. CIE plenary conferences are held every two years, and because of the CIE’s leading role are a place for our partner organizations and stakeholders to come together and integrate their work under the umbrella of the CIE. Not only were high-level delegates with special interest from several countries present (Oman, Algeria, Czech Republic) but also organizations like LUCI (Lighting Urban Communities International), ISO TC-274, the International Color Consortium (ICC), Dark Sky, the European Patent Office, and many more.
