IEC 60929 is an international standard created by the International Electrotechnical Commission and covers electronic ballasts used in AC supplies with voltages up to 1000 V and with operating frequencies at 50 Hz or 60 Hz. The actual operating frequency may deviate from the specified supply frequency. {{cite web |title=IEC 60929:2006 |url=https://www.iecee.org/dyn/www/f?p=106:49:0::::FSP_STD_ID:18414 |access-date=28 February 2022}}

The standard essentially covers the same material as IEC 60921, but it is considerably more complex due to the high frequency aspect of electronic ballasts. Appendix E of the standard defines the DALI, which specifies how ballasts are controlled.
