CIE D2 strategy
• Technical committee work – Increase of efficiency (Webex collaboration, work plans,
deadlines…) – Focus on relevant topics (update of basic documents, LED
photometry) • Scientific symposia
– Selected topics (Monte Carlo, Sampling theory, Advanced correction methods…)
• Tutorials and Lectures
– Increased demand from industry (Measurement uncertainty)

CIE TC2-71 CIE Standard on test methods for LED Lamps, luminaires and modules Chair, Yoshi Ohno (US)
developed a CIE standard
Joint work with
CEN TC169 WG7 Photometry, Chair, Guy Vandermeersch (BE)
developed an equivalent EN standard on SSL test method:
CIE DIS 025 is to be CIE S 025, then ISO/CIE/(IEC) joint standard
