Abstract (English)	Lighting is known to have an impact on humans, and clinical research is being carried out on the biological and physiological effects of light on sleep, health and wellbeing. Wearable light loggers, or radiation dosimeters, are light-weight wireless devices comprising one or multiple light sensors, filters and associated electronics logging time series data or summary metrics deduced from those data. Wearable light dosimeters have been used to assess the light exposure of humans. Though standardised methods and metrics have been introduced (CIE S 026 (2018)), calibration and characterisation of such dosimeters remains challenging. Guidance on providing traceability for wearable light dosimeters is therefore needed. This project aims to provide the scientific and industrial communities with the necessary tools (e. g. best practice guides) for the characterisation and use of wearable light loggers, as well as for the evaluation of the data produced.
