IEC 60081 Flicker Testing of Tubular Fluorescent Lamps
The International Electrotechnical Commission (IEC) standard IEC 60081 is a foundational document that addresses the flicker measurement and evaluation of lighting systems, including tubular fluorescent lamps. This testing ensures that artificial lighting environments are not only efficient but also safe for human visual perception. Flicker in lighting sources can cause discomfort, eye strain, and even potential hazards if it exceeds acceptable limits.
Understanding the flicker characteristics of a lamp is crucial for several reasons:
- Visual Comfort: Prolonged exposure to flickering lights can lead to visual discomfort and fatigue. This is particularly important in environments where people spend extended periods performing visually demanding tasks.
- Safety: In critical applications such as hospitals, flicker can disrupt medical equipment or cause accidents if it interferes with the operator's ability to see clearly.
- Ergonomics: Flicker can affect productivity and job satisfaction in office environments by causing discomfort. It is essential for maintaining a high level of comfort and well-being.
- Energy Efficiency
The IEC 60081 standard provides a method to measure the flicker index (FI), which quantifies how much a light source deviates from a constant value. The flicker index is calculated based on the root mean square (RMS) of the instantaneous luminous flux divided by its average value over a given period.
The standard specifies that the flicker test should be conducted under specific conditions to ensure accurate results. These include:
- Test Setup: The lamp must be installed in an environment with controlled temperature, humidity, and lighting conditions to avoid any external factors influencing the flicker measurement.
- Spectrometer Calibration: The spectrophotometer used for measuring light intensity should be calibrated according to IEC standards to ensure precise measurements.
- Data Collection: Continuous data collection over a defined period is necessary to capture the full spectrum of flicker behavior. Typically, this involves recording the luminous flux at intervals as short as 10 microseconds.
- Analytical Software: Advanced software tools are used to analyze the collected data and calculate the flicker index according to IEC 60081. These tools can also provide insights into the root causes of flicker, such as voltage fluctuations or mechanical imperfections in the lamp.
The acceptance criteria for a pass/fail result are based on the calculated flicker index and its relationship with the nominal frequency of the alternating current (AC) supply. Typically, if the flicker index exceeds 30% at the nominal frequency, the lamp is considered to have unacceptable flicker.
In summary, IEC 60081 flicker testing ensures that tubular fluorescent lamps meet stringent international standards for visual comfort and safety. This testing plays a vital role in maintaining high-quality lighting environments across various sectors, including commercial, industrial, and residential applications.

Environmental and Sustainability Contributions
The IEC 60081 flicker testing contributes significantly to environmental sustainability by promoting the use of energy-efficient lighting systems. Tubular fluorescent lamps, when tested for flicker according to this standard, can help reduce visual discomfort and improve indoor air quality. This, in turn, leads to reduced healthcare costs and improved productivity.
By ensuring that lamps meet IEC 60081 standards, manufacturers can contribute to a more sustainable future by:
- Reducing Visual Strain: Flicker-free lighting minimizes eye strain, which is particularly important in environments where people spend long hours working with computers or other visual tasks.
- Enhancing Workplace Well-being: Comfortable and well-lit workspaces contribute to better mental health and overall well-being. This can lead to increased job satisfaction and reduced absenteeism.
- Supporting Sustainable Design: Compliance with international standards encourages the development of environmentally friendly lighting solutions that are both energy-efficient and flicker-free.
- Promoting Eco-Friendly Manufacturing: By adhering to stringent testing protocols, manufacturers can reduce waste and improve resource efficiency during production processes.
- Encouraging Responsible Consumer Behavior: Educating consumers about the importance of flicker-free lighting can lead to more informed purchasing decisions, which in turn supports sustainable consumption patterns.
- Supporting Green Building Certifications: Compliance with IEC 60081 standards is often a prerequisite for obtaining green building certifications such as LEED or BREEAM. These certifications are increasingly important in promoting sustainable construction practices.
In conclusion, the IEC 60081 flicker testing plays a vital role in enhancing environmental sustainability by fostering the development and use of energy-efficient, flicker-free lighting systems. This not only benefits users but also contributes to a more sustainable future for all.
