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. 

Key Highlight:  

• 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 After this date, IS 16103 (Part 1):2012 will be withdrawn, and only the 2025 edition will remain valid.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 added for:

• Replaceable LED module

• Non-replaceable LED module

• 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.

• New information added for luminaire design regarding working voltage and water contact.

• Abnormal temperature test and Photobiological safety test are included.

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.
