IEC 62442-1:2022

Overview

IEC 62442-1:2022 - Energy performance of lamp controlgear, Part 1 - specifies a standardized method to measure the total input power of controlgear‑lamp circuits for fluorescent lamps and a calculation method to determine controlgear efficiency. Applicable to controlgear circuits consisting only of the controlgear and the lamp(s), the standard covers AC or DC supplies up to 1 000 V at 50 Hz or 60 Hz. This third edition (2022) replaces the 2018 edition, has been harmonized with Parts 2 and 3 of the series, and incorporates measurement methods for non‑active (standby) power referenced from IEC 63103.

Key Topics

• Scope and applicability
  • Measurement and calculation for controlgear used with linear double‑capped, single‑ended compact, and other general-purpose low‑pressure fluorescent lamps (per IEC 60081, IEC 60901).
  • Exclusions include controlgear integral to a lamp, controllable wire‑wound magnetic controlgear, and luminaires relying on additional optical performance aspects.
• Measurement methods
  • Defined procedures to measure the total input power of electromagnetic and electronic controlgear‑lamp circuits.
  • Normative measurement set‑ups described (Annex A) for accurate test connections and light output measurement.
• Efficiency calculation
  • Calculation rules to express controlgear efficiency while accounting for lamp operation and ballast lumen factor corrections.
• Standby and networked standby
  • Procedures for measuring standby power and networked standby power, using referenced non‑active power methods (IEC 63103).
• Reporting and sampling
  • Requirements for test sampling, conditioning, test voltages/frequencies, and standardized reporting of power measurements.

Applications

Who uses IEC 62442-1:2022 and why:

• Manufacturers of lamp controlgear - to verify energy performance claims, optimize designs, and support product datasheets.
• Test laboratories and certification bodies - to perform repeatable, comparable measurements for compliance testing and efficiency verification.
• Regulators and energy program managers - to define measurement bases for minimum energy performance standards or incentive programs.
• Specifiers and procurement teams - to compare controlgear efficiency and total input power when selecting components for lighting systems (noting the standard applies to controlgear alone, not whole luminaires).
• R&D and product development - to evaluate electromagnetic vs electronic controlgear performance and standby behaviors.
