1. Scope of CSA C827-10 (2015)
1. Scope of CSA C827-10 (2015)
CSA C827-10 (2015) establishes minimum energy performance requirements for high-intensity discharge (HID) lamps and luminaires used in general lighting applications. The standard applies to metal halide and high-pressure sodium lamps with a rated wattage of 50 W and above, as well as to luminaires designed for these lamp types. It covers products marketed for commercial, industrial, and outdoor applications, including street lighting, parking lot lighting, and warehouse illumination.
The standard defines energy efficiency criteria such as minimum luminous efficacy (lumens per watt) for lamps and minimum luminaire efficacy ratings for complete lighting units. It also specifies test methods, measurement tolerances, and marking requirements to ensure consistent evaluation and compliance.
Key Objective: CSA C827-10 (2015) aims to reduce energy consumption in Canada by eliminating inefficient HID lighting products from the market, aligning with broader energy conservation policies.
This standard is part of a broader regulatory framework that includes Canada’s Energy Efficiency Regulations. It applies to products that are manufactured in or imported into Canada, and compliance is mandatory for sale or lease in the country. The 2015 edition revises the previous C827-10 version to incorporate updated testing procedures and more stringent efficacy thresholds.
2. Technical Requirements
2.1 Minimum Efficacy for Lamps
Subclause 4.2 of CSA C827-10 (2015) specifies the minimum initial luminous efficacy that HID lamps must achieve at rated voltage and frequency when tested in accordance with ANSI C78.389. The requirements vary by lamp type and wattage. Metal halide lamps are divided into standard and high-efficiency categories, while high-pressure sodium lamps are classified by lamp type (standard, improved color, or low-wattage).
Important: Efficacy values are based on the lamp alone (bare lamp test) with a ballast that meets the appropriate ANSI standard. Luminaire performance is assessed separately.
| Lamp Type | Wattage Range | Minimum Efficacy (lm/W) |
|---|---|---|
| Metal Halide – Standard | 50 – 100 | 80 |
| Metal Halide – Standard | 101 – 175 | 90 |
| Metal Halide – High Efficiency | 50 – 100 | 90 |
| Metal Halide – High Efficiency | 101 – 175 | 100 |
| High-Pressure Sodium – Standard | 50 – 100 | 85 |
| High-Pressure Sodium – Standard | 101 – 175 | 105 |
| High-Pressure Sodium – Improvement | 50 – 175 | 70 |
Note: The above values are illustrative examples. Refer to the official standard for the complete table.
2.2 Luminaire Efficacy Requirements
Section 5 of the standard defines minimum luminaire efficacy, which accounts for the complete unit including lamp, ballast, and optical assembly. Luminaires must achieve a minimum effective luminaire efficacy (LEE) of 60 lm/W for most general-purpose types, with stricter limits for certain applications. Testing must be performed using a goniophotometer or integrating sphere per the procedures of CSA C838‑13.
Tip: When designing new luminaires, selecting high-efficiency ballasts (electronic or low-loss magnetic) and high‑efficacy lamps can help meet both lamp and luminaire requirements with margin.
2.3 Testing Conditions and Tolerances
All efficacy measurements must be conducted at an ambient temperature of 25 °C ± 1 °C, with a controlled voltage of 120 V ± 0.5 % for units rated at 120 V (or 277 V ± 0.5 % for 277 V products). The standard allows a tolerance of 95 % of the reported value for initial lumen output, and 90 % for luminaire efficacy. Manufacturers must report test results based on at least three units of the same model.
3. Implementation Highlights
3.1 Transition Period and Phase-In
For products that previously complied with the 2010 edition, manufacturers were given a transition period of one year from publication (2015) to update designs and retest. New product introductions were required to meet the 2015 requirements immediately.
Caution: Relying on legacy test reports from the 2010 edition may lead to non-compliance. All testing must be performed or updated to the 2015 test methods and tolerances.
3.2 Marking and Documentation
Each lamp and luminaire must bear a permanent marking indicating the lamp type, rated wattage, nominal initial efficacy, and the certification mark of an accredited agency (e.g., CSA, UL, or Intertek). The accompanying user manual or technical data sheet must include the rated luminous flux, color rendering index (if applicable), and ballast type.
3.3 Exemptions and Special Cases
CSA C827-10 (2015) does not apply to HID products rated below 50 W, to lamps and luminaires intended for emergency lighting, to those used in hazardous locations certified under CSA C22.2, or to products designed solely for ultraviolet or infrared radiation. Manufacturers must clearly exempt such products from the scope through labelling.
Compliance Benefit: Meeting CSA C827-10 (2015) not only satisfies Canadian regulations but often leads to higher energy star ratings, reduced operational costs, and eligibility for utility rebate programs.
3.4 Best Practices for Design and Procurement
Engineers should specify electronic ballasts for metal halide lamps, as these improve efficacy by up to 15 % compared to magnetic ballasts. For high-pressure sodium, pulse-start technology provides higher efficacy and faster warm‑up. Procurement teams should request certified test reports from suppliers and verify that the listed efficacy values are within the allowed tolerance.
4. Compliance Notes
4.1 Regulatory Enforcement
In Canada, CSA C827-10 (2015) is referenced by the Energy Efficiency Regulations under the Energy Efficiency Act. Natural Resources Canada (NRCan) enforces compliance, and non‑compliant products can be removed from the market, with potential penalties of up to CAD 1.5 million for repeat violations. Provincial authorities may also apply additional requirements.
Warning: Importers and manufacturers must maintain records of test data and compliance declarations for at least six years. Failure to do so may result in immediate suspension of product sales.
4.2 Certification and Third-Party Testing
CSA C827-10 (2015) does not require mandatory third-party certification; however, most retailers and utilities require products to carry a certification mark from a recognized body (CSA, UL, ETL). Self-declaration is permitted if the manufacturer’s test laboratory is accredited to ISO 17025. In either case, the test report must be available upon request.
4.3 Maintenance of Compliance During Production
Manufacturers must have a quality control plan that includes periodic verification – at least once every 24 months – that production units continue to meet the standard. Changes in component suppliers (ballast type, lamp arc tube) require a new full‑efficacy test.
4.4 Updates and Amendments
As of 2026, CSA C827-10 (2015) remains current. However, industry stakeholders should monitor NRCan consultation notices for potential amendments that may lower efficacy thresholds in line with advancements in LED technology, which is now cutting into HID market share.
Q: Does CSA C827-10 (2015) apply to LED replacement lamps for HID fixtures?
A: No. LED lamps and luminaires are covered by separate standards, such as CSA C819‑16 (for SSL) or the ENERGY STAR V2.0 specification. This standard is specific to HID technologies (metal halide and high-pressure sodium).

Q: Can I use a C827-10 compliant lamp in a luminaire certified to the 2010 edition?
A: Yes. The lamp and luminaire requirements are independent. As long as the lamp meets the lamp efficacy table (Table 1) and the luminaire meets its own efficacy requirement, the combination is acceptable. However, the complete luminaire’s performance must also be verified if it is sold as a unit.

Q: Are there any exemptions for specialty coatings or high color rendering versions?
A: The standard does not provide blanket exemptions for high CRI models. However, lamps that are clearly marketed for specialized applications (e.g., stage lighting or UV curing) may be excluded if they fall outside the defined scope of “general lighting”. It is recommended to submit a formal interpretation request to CSA Group.

Q: What should I do if my product is failing the luminaire efficacy test?
A: Consider upgrading the ballast to an electronic type, optimizing the reflector design to reduce losses, or selecting a lamp with higher efficacy. Also ensure the testing temperature is within spec, as high ambient temperatures reduce lumen output.
