The Bureau of Indian Standards (BIS) has revised IS 16103 (Part 1):2012 and published it as IS 16103 (Part 1):2025 / IEC 62031:2018. This standard specifies the safety requirements for LED modules used in general lighting.

Highlight Point:  

  • Both the old (2012) and new (2025) versions will run concurrently up to 21st  January 2026. After this date, IS 16103 (Part 1):2012 will be withdrawn, and only the 2025 edition will remain valid.

Key Changes: 

  • New definitions have been added for replaceable LED module, non-replaceable LED module, and non-user replaceable LED module. 
  • The marking clause has been restructured, and an overview table has been introduced. 
  • Marking requirements for built-in LED modules have been modified. 
  • The entry for working voltage marking has been updated. 
  • Annexe B has been deleted. 
  • Information for luminaire design with regard to working voltage and water contact has been added. 
  • An abnormal temperature test has been included. 
  • A photobiological safety test has also been added.

Important points for existing licensees:

  • All licensees must shift to IS 16103 (Part 1):2025 / IEC 62031:2018 by 21 January 2026. After this deadline, licences based on the 2012 standard will no longer be valid. 
  • Licensees must submit complete test reports from BIS-recognised laboratories for all lead models under their licence that were earlier tested as per the 2012 edition. 
  • Licensees must also provide an undertaking confirming that all other series models under their licence meet the requirements of the 2025 edition. 
  • Failure to comply with the deadline may lead to cancellation of the licence or deletion of models from the licence scope. 

Important points for new applicants:

  • Applications already under process (samples submitted/test reports issued) may continue under the old 2012 standard. 
  • Fresh applications may be processed as per either the old or revised standard until the last date of implementation. Applicants choosing the old standard must give a declaration that they will switch to the 2025 edition by the deadline. 
  • After 21 January 2026, all new licences will only be granted as per the revised standard. 

Change in Scope of Licence 

  • Requests for change in scope will follow the same provisions as for new applicants. 
  • Such changes under the old standard will only be allowed until either the licensee switches over to the new standard or until the implementation deadline, whichever is earlier.
