CAN/CSA C819-16: Performance Requirements for LED Lamps, Light Engines, and Luminaires

Introduction

As LED lighting continues to dominate the general illumination market, ensuring consistent performance across products becomes critical for consumer confidence and regulatory compliance. CAN/CSA C819-16, published by the Canadian Standards Association, establishes uniform performance requirements for LED lamps, LED light engines, and LED luminaires intended for use in dry, damp, or wet locations. This standard applies to products operating at line voltages (120 V–277 V) or extra-low voltage, and covers a wide range of general lighting applications including residential, commercial, and industrial settings.

First published in 2011 and reaffirmed with updates in 2016, CAN/CSA C819-16 aligns closely with international benchmarks such as IES LM‑79, IES LM‑80, and ANSI C78.377, while incorporating specific provisions for the Canadian market. This article examines the scope, technical requirements, implementation considerations, and compliance pathways defined by this important standard.

Key purpose: CAN/CSA C819-16 provides minimum performance criteria to ensure that LED lighting products deliver acceptable light output, colour quality, electrical performance, and longevity in the field.

Scope of CAN/CSA C819-16

The standard covers:

LED lamps — self-ballasted LED lamps with ANSI base types (e.g., E26, E12, GU24) that replace conventional incandescent or compact fluorescent lamps.
LED light engines — non-replaceable light sources integrated into luminaires, including modules and arrays.
LED luminaires — complete lighting fixtures incorporating LED light engines, intended for general illumination.

Excluded from the scope are LED products designed for signage, traffic signals, horticultural lighting, and other niche applications. The standard applies equally to products with or without integral dimming or control features, but does not address interactive performance with specific control systems.

Technical Requirements

Photometric Performance

Luminous flux (lumens): Stated initial lumens must be within ±10% of the measured value. Minimum flux levels are specified for certain lamp types in replacement applications.
Correlated Colour Temperature (CCT): Products must meet the tolerances of ANSI C78.377. For nominal CCTs of 2700 K, 3000 K, 3500 K, 4000 K, 5000 K, and 6500 K, the actual measured CCT must lie within a 7-step MacAdam ellipse (or tighter).
Colour Rendering Index (CRI): A minimum CRI of 80 is required for most indoor applications, with a higher minimum of 90 for products claiming high colour quality. The standard also specifies colour fidelity and gamut if R9 (strong red) is declared.
Lumen maintenance: Lumen depreciation at 6000 h must be ≤5% (corresponding to L70 lifetime projection of at least 25 000 h). Projected L70 life (per IES LM‑80 and TM‑21) must be declared.

Electrical Performance

Input power: Measured input power shall not deviate by more than ±10% from the rated value, and must be ≤ the maximum allowed by the standard for the product category.
Power Factor (PF): For lamps and luminaires rated at >5 W, a minimum PF of 0.7 is required; for >25 W, the minimum PF is 0.9 (for residential) and 0.9 (for commercial).
Total Harmonic Distortion (THD): THD of input current shall not exceed 20% for products >25 W, and 30% for products >5 W.
Standby power: If the product includes a standby mode (e.g., remote control receiver), standby power consumption must be ≤0.5 W.

Reliability and Lifetime

Endurance test: LEDs must operate without early failure for a minimum of 6000 h under accelerated conditions (ambient temperature of 45 °C for indoor rated products).
Thermal management: The maximum case temperature (Tc) under worst‑case conditions shall not exceed the manufacturer’s rating. In‑situ temperature measurements are required.
Mechanical/electrical robustness: Vibration, humidity cycling, and dielectric strength tests as specified in CSA C22.2 No. 250 series.

Marking and Labeling

Permanent marking on the product must include: rated voltage/frequency, nominal wattage, nominal lumens, CCT, CRI, PF, and L70 life (in hours).
The package shall also contain the lumen maintenance curve or the percentage of initial lumens at 6000 h.
A Canadian regulatory compliance mark (e.g., CSA or cUL) must be affixed after certification.

Implementation and Testing

Tip: All measurements required by CAN/CSA C819-16 must be performed after a 100 h stabilization period (per IES LM‑79) in a controlled ambient temperature of 25 °C ±1 °C. Frequent changes in ambient conditions can skew CCT and luminous flux results.

The standard mandates testing on a minimum of five samples for initial performance and ten samples for lumen maintenance projections. Sampling must represent the typical production distribution. Testing laboratories should be accredited to ISO/IEC 17025 for the relevant test methods.

Key test protocols include:

IES LM‑79-19: Electrical and photometric measurements of solid-state lighting products (goniophotometry or integrating sphere).
IES LM‑80-15: Lumen maintenance testing of LED packages, arrays, and modules (conducted at three temperatures: 55 °C, 85 °C, and one selected by the manufacturer).
IES TM‑21-19: Extrapolation of LM‑80 data to project L70, L80, and L90 lifetimes.

For Canadian certification, the product must also meet applicable safety requirements (e.g., CSA C22.2 No. 250 series). Performance testing under CAN/CSA C819-16 is typically combined with safety testing during certification to a recognized mark.

Compliance and Certification Notes

Warning: Compliance with CAN/CSA C819-16 is not mandatory for all LED products sold in Canada, but many provincial energy efficiency regulations (e.g., NRCan’s Energy Efficiency Regulations) reference it. Sellers must verify the specific product category requirements.

To demonstrate compliance, manufacturers typically:

Obtain third-party certification from a Standards Council of Canada accredited body (e.g., CSA, cUL, Intertek).
Submit test reports covering photometry, electrical, and thermal performance.
Provide LM‑80 data on the LED package and TM‑21 projections for lifetime.

The standard also includes provisions for periodic verification – certified models must be retested every three years or whenever a significant design change occurs (e.g., change in LED source, driver, or thermal design).

Important: Products that fail to meet the minimum CRI of 80 or that exhibit a lumen maintenance failure at 6000 h cannot bear a mark of compliance under CAN/CSA C819-16. Such products must be relabeled as “for industrial use only” or removed from the Canadian market.

Frequently Asked Questions

Q: Is CAN/CSA C819-16 equivalent to ENERGY STAR® requirements for LED lamps?
A: Not identical, but closely aligned. CAN/CSA C819-16 sets minimum performance thresholds, while ENERGY STAR adds efficacy tiers and additional features (e.g., rapid‐cycle stress). Canadian regulations often accept CSA C819‑16 test data for ENERGY STAR qualification if the product also meets the ENERGY STAR specification.

Q: Does CAN/CSA C819-16 apply to LED fixtures with integrated controls (e.g., occupancy sensors)?
A: Yes, the standard covers LED luminaires with integral controls. However, the control functionality itself (sensing accuracy, dimming range) is not evaluated – only the LED light engine performance and standby power are tested.

Q: Can a product certified under IATF 16949 (automotive) or IEC 62722‑1 be used in Canada without C819?
A: No. While IEC 62722‑1 is a global performance standard, Canada requires specific safety and performance certification per CSA/UL standards. A product bearing only IEC certification is generally not accepted by provincial authorities unless it also holds a recognized Canadian mark.

Q: How often must lumen maintenance data be updated if the product remains unchanged?
A: The standard does not require ongoing testing if no changes are made. However, the certification body may request updated data every three years to ensure the LED package manufacturer’s LM‑80 data is still current and the product continues to meet the performance claims.

When designing or sourcing LED products for the Canadian market, referencing CAN/CSA C819-16 is essential to ensure both compliance and quality. Industry stakeholders are encouraged to obtain the full standard from CSA Group (store.csagroup.org) and consult with an accredited testing laboratory for product-specific guidance.
