Metal halide lamp ballasts – May 2017

Technical bulletin on developing the standard

On April 30, 2016, Natural Resources Canada's Office of Energy Efficiency issued a Notice of Intent to amend Canada’s Energy Efficiency Regulations (the Regulations) to align metal halide lamp ballasts with standards in the United States. This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for metal halide lamp ballasts.

Input received during this stage of the process will inform the development of the Amendment 14 proposal.  In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of these new standards and to ensure Canadian consumers and businesses benefit from their implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I, within approximately two years of this bulletin.

Background

In 2014, the Canada-United States Regulatory Cooperation Council committed to align new and updated energy efficiency standards and test standards for energy-using equipment, to the extent practicable and permitted by law.

Metal halide lamp ballasts are not currently an energy using product in Canada. In December 2007, the United States Energy Independence and Security Act (EISA 2007) was signed into law, which set out minimum energy performance standards (MEPS) for metal halide lamp fixtures and consequently, the ballasts they contained.  These efficiency levels apply to fixtures manufactured on or after January 1, 2009. For the purposes of this bulletin, these levels will be referred to as “Tier 1”.

On February 10, 2014, the United States Department of Energy (U.S. DOE) issued a final rule, which increased the stringency of the Minimum Energy Performance Standards (MEPS) and expanded the scope to include coverage for additional ballast types. These new MEPS come into force on February 10, 2017. For the purposes of this bulletin, these levels will be referred to as “Tier 2”.

Given that the expected date of publication of Amendment 14 will be nearly 2 years after the U.S. implementation of the Tier 2 MEPS, with an additional six months delay before the regulations come into force, Natural Resources Canada (NRCan) is considering forgoing the Tier 1 MEPS altogether and directly adopting Tier 2 MEPS, with additional consideration for 347 V ballasts, which are specific to Canada.  If implemented, this proposal would ensure the Regulations for metal halide lamp ballasts are generally aligned with those of the U.S. DOE.

Product description

A metal halide lamp ballast is a device used with a metal halide lamp to obtain necessary circuit conditions (voltage, current, and waveform) for starting and operating the lamp.

The definition of metal halide lamp ballasts would exclude:

  • regulated-lag ballasts
  • electronic ballasts that operate at 480 volts
  • high-frequency electronic metal halide lamp ballasts

Energy performance test procedure

NRCan is considering referencing the following energy performance testing standard:

  • CSA-C863-16 - Energy efficiency of high-intensity discharge (HID) and low-pressure sodium (LPS) lamp ballasts

The testing standard can be ordered from:

Important dates

These regulations would come into force six months after the date of publication in the Canada Gazette, Part II.

NRCan proposes that the new standards would apply to metal halide lamp ballasts manufactured on or after February 10, 2017.

Verification requirements

NRCan proposes that these products carry a third party verification mark indicating that the product meets the MEPS and that information to be reported has been verified.

The verification mark is the mark of a Standards Council of Canada accredited certification body that operates an energy efficiency certification program for the product.

Reporting requirements

Energy efficiency reports

The energy efficiency report required for metal halide lamp ballasts would include the following information:

  • name of product (i.e. metal halide lamp ballast)
  • brand name
  • model number
  • name of the manufacturer
  • name of the certification body whose verification mark will be affixed to the product
  • ballast efficiency in percentage
  • the rated ballast input voltage or range of voltages
  • the rated wattage of the lamp the ballast is designed to operate

The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded interprovincially for the first time.

Import reports

A dealer who imports these products into Canada would include the following information on the customs release document:

  • name of product
  • model number
  • brand name
  • address of the dealer importing the product
  • purpose for which the product is being imported (i.e. for sale or lease in Canada without modification; for sale or lease in Canada after modification to comply with energy efficiency standards; or for use as a component in a product being exported from Canada) 

Comments invited

The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for metal halide lamp ballasts. 

Natural Resources Canada is specifically interested in getting feedback on:

  • the effective date of the MEPS.
