Comprehensive Guide to CAN/CSA C22.2 No. 62560-16: Self-Ballasted LED Lamps – Safety and Performance Requirements
Understanding the Canadian National Standard for LED Lamps under the Canadian Electrical Code
Scope and Application
CAN/CSA C22.2 No. 62560-16 is a National Standard of Canada adopted from IEC 62560:2011 (with up-to-date amendments), developed under the Canadian Electrical Code framework. It specifies safety and interchangeability requirements, together with test methods and conditions, for self-ballasted LED lamps intended for domestic and similar general lighting purposes. These lamps incorporate an integrated control gear (ballast) and are designed for operation on AC or DC supplies up to 250 V. The standard applies to lamps with rated wattage up to 60 W and with caps listed in relevant cap standards such as IEC 60061-1. It covers all types of integrated LED lamps that are not replaceable by the end user without permanent damage to the lamp, including those with retrofit bases (e.g., E26, E27, GU10, etc.).
Note: This standard is referenced by the Canadian Electrical Code (CE Code) Part I (CSA C22.1) for the installation of self-ballasted LED luminaires and lamps, ensuring a consistent regulatory approach across Canada.
The standard does not apply to LED modules or non-integrated control gear, which are covered by other standards (e.g., CSA C22.2 No. 250 series or IEC 62031). It also excludes lamps intended for special purposes such as industrial explosive atmospheres, aviation, or medical applications where specific performance criteria take precedence.
Key Technical Requirements
The technical requirements of CAN/CSA C22.2 No. 62560-16 are structured around ensuring user safety, interchangeability, and reliable operation under normal and fault conditions. The main categories include:
Electrical and Mechanical Specifications
| Parameter | Requirement | Test Clause |
| Rated Voltage Range | 50 V a.c. – 250 V a.c. / 120 V d.c. – 250 V d.c. | 6.1 |
| Rated Wattage | Up to 60 W | 1.1 |
| Cap Design | Per IEC 60061-1 or relevant CSA cap standard | 4.2 |
| Maximum Ambient Temperature | Typically 25 °C; special marking for higher | 12.1 |
| Case Temperature (tc) | Limited per lamp design; must not exceed 95 °C | 13.1 |
| Dielectric Strength | No breakdown at 2U + 1000 V for 1 min | 9.1 |
| Leakage Current | ≤ 0.5 mA for DC; ≤ 0.7 mA peak for AC | 9.2 |
| Flicker (PstLM) | ≤ 1.0 (subjective visibility limit) | Annex B |
| Lamp Life (claimed) | Minimum 6 000 h (typical rated life) | Annex D |
Safety Criteria
Protection against electric shock: Lamps must be designed so that live parts are not accessible when the lamp is installed in a compliant lampholder. The standard specifies requirements for creepage distances and clearances based on the working voltage and pollution degree (typically pollution degree 2). For extra-low-voltage versions (≤50 V a.c. or ≤120 V d.c.), additional isolation may be required.
Design Tip: When designing for Canadian approval, ensure that the lamp’s internal surfaces are free from sharp edges that could damage insulation, and that the capacitor discharge circuit reaches ≤60 V within 1 s of removal from supply.
Thermal management: The standard mandates that the lamp must not cause its own or surrounding component temperatures to exceed defined maximum values. A thermal test is conducted with the lamp operated at its rated voltage and in the worst-case orientation (typically base up). The measured temperature of the cap (tc point) must not exceed the lamp’s rated cap temperature.
Testing and Verification
Compliance requires successful completion of type tests performed in a laboratory accredited to ISO/IEC 17025 and recognized by the Standards Council of Canada (SCC) or a CSA-accepted certification body. The main test sequences are outlined below.
- Visual inspection and marking – verify that the lamp is marked with rated voltage, wattage, frequency, cap type, source of light (LED), and the manufacturer’s name or trademark.
- Dimensional checks – ensure the cap and overall dimensions comply with the relevant data sheets (IEC 60061-1).
- Electrical tests – measure power consumption, power factor, and harmonic content (must meet limits of IEC 61000-3-2).
- Dielectric strength and insulation resistance – performed after damp heat conditioning.
- Abnormal operation – the lamp is subjected to short‑circuit and open‑circuit of control gear components; no fire hazard or electric shock may occur.
- Endurance and life test – operate the lamp for a specified number of cycles (6 h on, 1 h off) at a voltage equal to 1.1 times the rated voltage. After the test, the lamp must still operate and the cap temperature must not have exceeded the maximum by more than 10 %.
Warning: Sample failures during the abnormal operation test often result from inadequate thermal cut‑off or use of non‑approved PCBs. It is strongly recommended to perform a FMEA (Failure Mode and Effects Analysis) early in the design phase.
Good Practice: Many manufacturers have found that incorporating a built‑in PTC thermistor in the control gear improves both inrush current limitation and over‑temperature protection, increasing the likelihood of passing the abnormal operation tests on the first attempt.
Implementation and Compliance Considerations
To bring a self-ballasted LED lamp to the Canadian market, manufacturers must follow the conformity assessment procedures laid out by the Standards Council of Canada and accredited certification bodies. The key steps include:
- Select a certification body (CB) like CSA Group, UL Canada, or Intertek (ETL).
- Submit samples for testing to the full requirements of CAN/CSA C22.2 No. 62560-16.
- Undergo a factory inspection to verify the manufacturing process and quality management system (ISO 9001 or equivalent).
- Obtain a certificate of compliance and authorization to apply the certification mark (e.g., CSA mark, cUL mark).
- Maintain ongoing surveillance – periodic unannounced factory audits and market surveillance testing are required to retain certification.
Marking and Instructions
The lamp must be marked with:
- Rated voltage (or range) and frequency in hertz.
- Rated wattage and lamp current.
- Cap designation (e.g., “E26”).
- Model/catalogue number.
- Production date (or code).
- “LED” or equivalent indication.
- WARNING text if the lamp is not suitable for use in enclosed luminaires or with dimmers.
Critical: Failure to include the required warning statements may result in rejection of the product by provincial electrical inspection authorities. For example, if the lamp does not have a noted maximum ambient temperature of 25 °C, it must be marked “For use in open luminaires only.”
Frequently Asked Questions
Q: Can a lamp certified to IEC 62560 be accepted directly in Canada without additional testing?
A: No. While CAN/CSA C22.2 No. 62560-16 is technically identical to IEC 62560, Canadian certification requires testing by a SCC‑accredited body to confirm compliance with any national differences (e.g., supply voltage tolerance, specific cap dimensions). CB certifications from IECEE can help reduce duplicate testing but do not replace a Canadian national certification mark.

CB certifications from IECEE can help reduce duplicate testing but do not replace a Canadian national certification mark.
Q: What is the maximum rated wattage covered by this standard?
A: The standard explicitly covers lamps up to 60 W. For lamps above 60 W, other standards apply, such as CSA C22.2 No. 250.0 for luminaires or IEC 60598-1 for LED luminaires.

Q: Are there special requirements for lamps intended for use in dimmable circuits?
A: Yes. The standard requires that dimmable LED lamps be tested for compatibility at the minimum and maximum dimming levels. The manufacturer must also provide a list of compatible dimmers. Additionally, the lamp must not exceed Class B harmonic limits when operated with a dimmer set at full output.

Additionally, the lamp must not exceed Class B harmonic limits when operated with a dimmer set at full output.
Q: How does the Canadian standard differ from the original IEC publication?
A: The main differences are editorial and relate to references that are replaced by CSA equivalents. For example, references to Canadian Electrical Code Part I (C22.1) and cap standards from CSA C22.2 No. 62560-16 are harmonized with the ICE and E‑cap‑data sheets recognized in Canada. A detailed list of deviations is provided in the National Preface of the standard.
