CSA C22.2 No. 159-18: Safety Requirements for Portable Luminaires
A Comprehensive Guide to Electrical and Construction Safety for Cord-Connected Luminaires in Canada
Introduction and Scope
CSA C22.2 No. 159-18 is the latest edition (2018) of the Canadian standard for the safety of portable luminaires. It applies to cord- and plug-connected luminaires intended for use on nominal branch circuits not exceeding 250 V and rated at 50 A or less. Typical products covered include floor, table, desk, and cabinet luminaires, portable hand lamps, and other movable lighting fixtures rated for dry, damp, or wet locations. The standard does not cover permanently installed luminaires, track lighting, or low-voltage systems under IEC/UL 60950. It is recognized by provincial regulatory authorities and is harmonized with UL 153 for North American market acceptance.
Tip: CSA C22.2 No. 159-18 is adopted in all Canadian provinces; compliance is mandatory under the provincial electrical codes. Check the latest amendment bulletins on the CSA Group website for updates on scope inclusions (e.g., LED conversion kits).
Technical Requirements
This standard prescribes construction, performance, and protective requirements to minimize the risk of fire, electric shock, and mechanical injury during normal and abnormal operation. The main requirements are organized by electrical, mechanical, thermal, and marking provisions.
Electrical and Mechanical Construction
All conductive parts must be adequately insulated, bonded, and protected against corrosion. Enclosures shall have a minimum thickness of 0.41 mm for steel and 1.2 mm for die-cast metal. For polymeric enclosures, a minimum glow-wire test rating of HBA at 850 °C is required. Grounding continuity shall be less than 0.1 ohm for cord-connected luminaires with metal enclosures.
| Test Parameter | Requirement | Applicable Products |
|---|---|---|
| Dielectric voltage withstand (basic insulation) | 1,250 V AC for 1 min | All portable luminaires |
| Grounding continuity | ≤ 0.1 Ω | Class I luminaires |
| Leakage current (normal operation) | ≤ 0.5 mA | All portable luminaires |
| Temperature rise on enclosure (polymer) | ≤ 75 °C (ambient 25 °C) | All portable luminaires |
| Impact test (drop height) | 0.9 m onto concrete | Portable hand lamps |
| Stability test (tilt angle) | 15° without tipping | Floor and table luminaires |
Luminaires intended for damp or wet locations must additionally pass water-ingress (IPX4 or higher) and corrosion resistance tests. For wet locations, all external fasteners shall be corrosion resistant or coated.
Lamp Control and Power Supply Requirements
The standard requires that built-in LED drivers or other power supplies comply with CSA C22.2 No. 250.13 (lamp control devices) and be subjected to overload and abnormal operation tests. If a manually operated switch is provided, it must have a contact gap of at least 3 mm for single-pole switching of a 120 V circuit.
Warning: Failure to meet the dielectric withstand and creepage distances (per IEC/CSA 60950) may lead to arc tracking on insulation. Design PCBs and spacings per the standard’s 2.5 mm minimum for 250 V working voltage.
Implementation Highlights
Adopting CSA C22.2 No. 159-18 during product design can streamline certification. Key points include:
- Cord selection: Minimum conductor size 0.824 mm² (18 AWG) for 120 V luminaires; must be SVT or SJT and marked type of outlet plug.
- Strain relief: Must prevent cord tension from being transmitted to internal connections; pull test of 35 lbf for 30 s without displacement.
- Replacement lamp protectors: A mechanical shield or mesh is required for any portable luminaire that uses a lamp that can shatter (e.g., incandescent > 60 W or any HID).
- Thermal sensors: Electronic thermal cut-offs (TCO) must automatically reset or be manually replaceable.
- Marking: Permanent marking on the product includes voltage, current, wattage or type of lamp, and location rating (e.g., “WET LOCATION”).
Success: Manufacturers that follow the standard’s requirements from the prototype stage average 30% fewer non-conformities during CSA inspection. Early compliance reduces project delays and costs.
Compliance Notes
To legally sell portable luminaires in Canada, products must be certified to CSA C22.2 No. 159-18 by an accredited certification body (e.g., CSA, UL, or Intertek). Certification typically involves:
- Initial type testing by the certification body on representative samples.
- Factory inspections (quarterly or bi-annual) with ongoing verification of critical components.
- Marking with the certification mark (e.g., CSA, cUL) and the standard number.
The standard also accepts component certifications: e.g., switches under CSA C22.2 No. 55, lamp holders under CSA C22.2 No. 43, and supply cords under CSA C22.2 No. 49. For LED luminaires, the enclosure glow-wire test (CSA C22.2 No. 0.17) may be required in lieu of the standard flame resistance test.
Danger: Using non-certified components voids the end-product listing. For example, installing a regular power supply that is not certified to CSA C22.2 No. 250.13 will cause the luminaire to be considered unlisted, exposing the manufacturer to liability and market recall.
The Canadian provincial codes (e.g., OESC, CEC) have specific adoption dates. As of 2026, CSA C22.2 No. 159-18 remains active, with a maintenance cycle that may propose amendments for new technologies such as IoT-connected luminaires and Li-ion battery backup systems. Manufacturers should monitor the CSA Group’s notifications.
Frequently Asked Questions
Q: Does CSA C22.2 No. 159-18 apply to portable LED trouble lights with battery packs?
A: Yes, if the luminaire is cord-and-plug connected (even if equipped with a rechargeable battery) and has a nominal input voltage not exceeding 250 V. Battery-only operation is covered under separate standards (e.g., CSA C22.2 No. 250.14).

Q: What is the relationship between CSA C22.2 No. 159-18 and UL 153?
A: CSA C22.2 No. 159-18 is technically harmonized with UL 153 (same edition year). Certification to one often satisfies the requirements of the other via the CAN/CSA‑C22.2 No. 0 series, allowing manufacturers to place a binational mark (cULus) for both Canada and the United States.

Q: Are there special requirements for luminaires with adjustable color temperature?
A: The standard does not yet have specific provisions for color‑tuning controls, but any control circuit must comply with the limited-power and circuit‑isolation clauses. Consult the certification body for a case‑by‑case evaluation.

Q: Do replacement LED lamps for existing portable luminaires need to comply with this standard?
A: No. The lamp itself is covered by CSA C22.2 No. 1993 (self‑ballasted LED lamps). However, if the lamp is integrated into the luminaire during manufacture, the whole product must comply with CSA C22.2 No. 159‑18.
