Fluorescent lamp ballasts

Energy Efficiency Regulations

Regulatory definition

Fluorescent lamp ballast, a device that:

  • is designed to start and operate fluorescent lamps by providing the necessary voltage and current, limiting the current during normal operation, and if necessary to facilitate lamp operation, providing cathode heating
  • is designed for a nominal voltage of at least 120 V, but not more than 347 V, and
  • is described in Table 1A of CSA C654-14

but does not include any of the following:

  • a ballast – other than a T12 dimming ballast - that, by means of an integrated dimming capability, is designed to reduce the output of the fluorescent lamp by 50% or more
  • a low-frequency T8 ballast that is designed and marketed only for use in an electromagnetic-interference-sensitive environment and that is sold in a package of 10 or fewer, or
  • a program-start ballast that is designed to operate one or more T8 fluorescent lamps with a nominal overall length of 1 200 mm and a medium bi-pin base, and that delivers an average current of less than 140 mA to each lamp

T12 dimming ballast, a fluorescent lamp ballast that:

  • is designed for a nominal voltage of at least 120 V but not more than 277 V
  • by means of an integrated dimming capability, is designed to reduce the output of a T12 fluorescent lamp by 50% or more, and
  • is designed to operate one F34T12 fluorescent lamp or two F34T12, F96T12ES or F96T12HO ES fluorescent lamps
