Of course compromises have had to be made, and in preparing the overview of the event the ISC has tried to mix things up so that there is opportunity to participate in different aspects of CIE 2021.

Below is the overview for day 1 of the conference and the complete programme outline and the draft detailed programme are published in the CIE 2021 website.

Each day CIE 2021 will officially run from 14:00 – 24:00 Malaysian time, in other time zones:

  • 19:00 – 05:00 next day NZDT (New Zealand),
  • 16:00 – 02:00 next day AEST (Australia east coast)
  • 08:00 – 18:00 CEST (Central Europe),
  • 03:00 – 15:00 BRT (Brazil)
  • 02:00 – 12:00 EST (North America east coast),
  • 23:00 – 09:00 PDT (North America west coast)
Registration is open. The  fees can be found on the CIE 2021 website with the early fees available until 2021-07-21.
CIE  S 026:2018 Now Available in  Chinese 
The CIE National Committee of China has prepared a translation into Chinese of CIE S 026:2018内在光敏视网膜神经节细胞受光响应的光辐射计量系统.

CIE S 026:2018 (CN) can be purchased from the CIE Webshop, as with all CIE translated publications the original English version is included within the translation. 

The translation of CIE S026 into Chinese is in addition to the Chinese translation and interpterion support that NC China are providing for the CIE tutorial on this standard. Registrations for this tutorial are open until Friday, so if you have been putting of registering for this tutorial there is still time to do this and have access to the tutorial materials before the live Q&A sessions.


CIE  Central Bureau Recruitment



To support the work of the CIE and be part of the team at the Central Bureau in Vienna, Austria, the CIE is recruiting a Scientific Manger (currently called CIE Technical Manager). The Scientific Manager plays a key role in the organization, including being responsible for the final steps in the preparation of all CIE publications and in their promotion to the world.

The job advert  is available for download if you want to learn more about this position.

Application for this role will be open until August 14, 2021 and requests for further information or submissions of applications should be sent to for the attention of the General Secretary.


Call for Experts for CIE Technical Committees


The CIE has over 70 TCs working on new technical reports and international standards. If you have expertise to contribute to any of these or the new ones highlighted below,  then you can apply for membership by sending in the CIE TC Membership form and CIE Copyright Agreement form  to CIE Central Bureau at for the TC Chair's consideration.

TC 2-95: Measurement of obtrusive light and sky glow

The purpose of this TC is to provide guidelines and examples for metrics, measurement methods and corresponding instrument specifications for the measurement of obtrusive light and sky glow including the estimation of measurement uncertainty contributions for the measurement, necessary to validate assessment criteria of its effects on the environment. The proposed guidelines and examples can be used as a common base with reliable and traceable techniques for various disciplines that are dealing with obtrusive light and sky glow measurements, light pollution assessment and research.

Chair: Constantinos Bouroussis (GR)
TC 2-96: Revision of ISO/CIE 19476: 2014 Characterization of the performance of illuminance meters and luminance meters

The purpose of this TC is to revise the Standard ISO/CIE 19476:2014 and CIE S 023/E:2013 respectively, taking into account the feedback received in the systematic review held in 2019.

Chair Armin Sperling (DE)

TC 3-59: The integration of daylight and electric lighting

The purpose of this TC is to define requirements for a lighting design approach that considers human comfort and wellbeing, as well as energy efficiency, taking into consideration the light spectrum in addition to the conventional design criteria based around illuminance or luminance.

Chair:  Peng Xue (CN)

TC 3-60: Spectral Daylight Characteristics

The purpose of this TC is to review geographical, seasonal and time-of-day variations in the spectral power distribution of daylight, when represented by D (daylight) illuminants. To update the CIE015:2018 reconstitution procedure to calculate D illuminants at a nominal correlated colour temperature. To provide spectral information for CIE standard general sky types.

Chair:  Martine Knoop (DE)

TC 8-18: Guidelines for Definition and Evaluation of High Dynamic Range Images and Image Sequences

The purpose of this TC is to propose a definition of High Dynamic Range (HDR) images and image sequences (Images, hereafter), including luminance level, contrast, and spatial/temporal distribution. To define luminance levels, observing environment, adopted white point, the kinds of Images to be used in research experiments and their assessment. To recommend methods of calculating key characteristics of the HDR Images.

Chair:  Mekides Assefa Abebe (NO)
