CSA C22.2 No. 250.0-18: Safety Standard for Lighting Products in Canada – Scope, Requirements, and Compliance
Comprehensive overview of the Canadian electrical standard governing the safety and performance of lighting equipment
1. Scope and Application
CSA C22.2 No. 250.0-18, titled Lighting products, is the primary Canadian safety standard for a broad range of lighting equipment. Published as part of the Canadian Electrical Code Part II (C22.2 series), the 2018 edition supersedes previous versions and aligns closely with UL 1598 while incorporating specific Canadian national differences.
The standard applies to all lighting products intended for connection to branch circuits not exceeding 600 V nominal and for use in non-hazardous locations in accordance with the Canadian Electrical Code (CE Code). Included are:
- Portable and fixed luminaires (indoor and outdoor)
- Track lighting systems
- Recessed, surface‑mounted, and pendant fixtures
- Emergency lighting units
- Lighting accessories (e.g., lamp holders, wiring boxes integral to the luminaire)
Excluded are products already covered by dedicated standards, such as stage lighting, automotive lighting, and appliances with integral lighting.
Tip: Manufacturers should verify that the latest edition of the standard is referenced by the authority having jurisdiction (AHJ) in the target Canadian province. While CSA C22.2 No. 250.0-18 is harmonized with UL 1598, some provincial amendments may exist.
2. Key Technical Requirements
CSA C22.2 No. 250.0-18 establishes comprehensive criteria for electrical, mechanical, and thermal safety. The following table summarises critical test parameters and their applicable limits.
| Parameter | Limit / Requirement | Test Condition |
|---|---|---|
| Grounding continuity | Impedance ≤ 0.1 Ω from grounding terminal to any exposed metal part | Using a power source (e.g., 12 V, 25 A) |
| Leakage current (Class I) | ≤ 0.5 mA for cord‑connected luminaires; ≤ 1.0 mA for fixed luminaires | At rated voltage and worst‑case orientation |
| Insulation resistance | ≥ 2 MΩ between live parts and accessible metal | After humidity conditioning (48 h at 96% RH, 30°C) |
| Normal temperature rise | Maximum 90°C on lamp terminals; 40°C on mounting surfaces (wood) | At rated load and voltage (10 h equilibrium) |
| Abnormal temperature | No ignition of cheesecloth; max 180°C on accessible parts | Fault conditions (e.g., lamp short circuit) |
| Mechanical impact (portable) | Drop test: 1.0 m onto hardwood without hazardous damage | 6 drops in worst‑case positions |
Beyond the table, other significant requirements include:
- Components: Critical components (lampholders, capacitors, wiring, etc.) must be certified or comply with recognized component standards.
- Wiring: Minimum wire size, insulation temperature rating, and strain relief for accessible wiring.
- Lamp control: For LED lighting, the standard imposes additional requirements for safety circuits and electronic drivers (subject to CSA C22.2 No. 250.13).
- Markings: Permanent marking of minimum supply wire temperature, type of lamps, maximum wattage, and environmental rating (indoor/outdoor).
Warning: Outdoor luminaires must meet additional rain‑resistance tests (spray test) and corrosion resistance. Pay special attention to gaskets and drainage openings to avoid water accumulation.
3. Implementation and Testing Highlights
Successful certification to CSA C22.2 No. 250.0-18 requires a structured approach during product development.
3.1 Pre‑compliance testing – Manufacturers are encouraged to perform internal testing per the standard’s requirements before submitting samples for certification. Thermal imaging and dielectric strength checks can reveal issues early.
3.2 Use of certified components – Specifying components that already carry a CSA or UL recognized mark greatly streamlines certification and reduces overall construction review time.
3.3 Documentation – The certification body will require a complete parts list, wiring diagrams, marking details, and test reports for critical subassemblies. All documents must clearly indicate the revision level.
Good practice: Design lighting products with a margin of at least 15–20% below maximum temperature limits to accommodate tolerance in production and aging. This approach reduces the risk of field failures and periodic re‑certification costs.
3.4 Sample selection – Test samples must represent the worst‑case combination of: lamp wattage, supply voltage, ambient temperature, and mounting configuration. For multi‑configuration products, each variant is evaluated, but careful “worst‑case” analysis can reduce the number of samples needed.
4. Compliance and Certification Notes
Compliance with CSA C22.2 No. 250.0-18 is mandatory under CE Code requirements for all lighting products sold or installed in Canada. Certification is typically granted by organizations accredited by the Standards Council of Canada (SCC), such as CSA Group, UL, or Intertek.
- The CSA mark (or equivalently recognized certification mark) signifies conformance to the standard.
- Products must be re‑evaluated if significant modifications are made (e.g., new LED driver, change in thermal management, different lamping options).
- The standard follows a periodic maintenance cycle; the next amendment (250.0‑xx) is expected in line with technological advances in solid‑state lighting and connectivity.
Field evaluations are sometimes possible for one‑off installations, but factory‑certified products are strongly preferred by inspectors.
Important: The 2018 edition introduced updated requirements for LED modules (e.g., protection against electric shock and thermal stress) and more stringent anomalous temperature tests. Products previously certified to earlier editions may require re‑testing for continued compliance.
For manufacturers targeting both Canada and the United States, the close harmonization of CSA C22.2 No. 250.0-18 with UL 1598 simplifies dual‑certification. Most accredited laboratories can run combined test programs to minimize duplication and cost.
Q: Does CSA C22.2 No. 250.0-18 apply to LED light fixtures?
A: Yes, the standard covers LED‑based luminaires and retrofit kits. However, the LED driver and control circuits must also comply with the specific Canadian standard CSA C22.2 No. 250.13 (or be certified as UL 8750 recognized).

Q: Is a CSA mark mandatory for all lighting products sold in Canada?
A: Generally, yes. Provincial electrical codes require that lighting products be certified by an accredited body and bear a recognized certification mark (CSA, cUL, cETL, etc.). Self‑declaration of compliance is not accepted.

Q: How often is the standard updated?
A: CSA C22.2 No. 250.0 is normally revised every 3–5 years. The 2018 edition replaced the 2012 version. Check the CSA Group website for the latest publication status.

Q: Can I use existing UL 1598 test data for CSA certification?
A: Yes, because CSA C22.2 No. 250.0-18 is technically identical to UL 1598 except for a few Canadian national differences. Most test data can be shared, but the differences (e.g., marking language, grounding wire colour, specific supply voltage) must be verified.
