Metal halide lamp ballasts

Energy Efficiency Regulations

Regulatory definition

Metal halide lamp ballast, a device that is used to obtain the voltage, current and waveform necessary for starting and operating a metal halide lamp that has a nominal power of at least 50 W but not more than 1000 W.

It does not include any of the following:

  • a magnetic-regulated lamp ballast
  • a replacement metal halide lamp ballast, or
  • an electronic ballast that is designed for a nominal voltage of 480 V or to operate a lamp at an output fre­quency of 1000 Hz or more

Compliance date

Manufactured on or after February 10, 2017, or
Manufactured on or after December 31, 2019 for ballasts capable of using a nominal voltage of 347 V

Compliant product models

Metal halide lamp ballasts as listed on NRCan’s searchable database

Testing standard

CSA C863-16

Energy efficiency regulations by province

Some provinces also have their own energy efficiency regulations for many of the federally regulated products – find out which ones!
