Defining the Flicker Index (PstLm)
Flickering light sources can cause eye fatigue, headaches and other health problems. Therefore, it is important that light sources are flicker-free or the level of flicker is low enough that it doesn’t adversely affect the health of users.
Measuring PstLm involves determining the flicker index for a given light source. This uses specialised equipment that allows the flicker value to be recorded accurately under different lighting conditions. In this way, we can determine whether a light source meets the requirements of norms and standards with regard to flicker.
As part of our services, we measure PstLm for a variety of light sources, including bulb, fluorescent lamp, LED and other types of lighting. This ensures that our customers can be confident that their light sources are safe for health and provide optimum comfort.
Standards and norms regarding flicker are set by various organisations and institutions. In Europe, the most important standards are EN 61000-3-3, EN 61000-4-15.
What does the implementation of the measurement look like?
1. The first step is to contact us to find out more about our services and to arrange a measurement.
2. The next step is to have the measurements carried out by our experienced professionals, who have the knowledge and skills needed to measure accurately and precisely.
3. Once the measurements have been completed, we analyse the results, which are carefully collated and reported. If required, we can provide the results in electronic or printed form.
4. Finally, we complete the job by providing full technical support to the client. In addition, we can offer advice on the interpretation of the measurement results and their application in practice.
