Abstract: Lighting, both natural and electric, constitutes one of the most important aspects of the life ofhuman beings, allowing us to see and perform our daily tasks in outdoor and indoor environments. The safety aspects of Iighting are self-evident in areas such as road Iighting, urban Iighting and also indoor Iighting. The use of photometers to measure lighting leveIs requires traceability obtained in accredited laboratories, which must provide an associated uncertainty. It is therefore relevant to study the impact of known uncertainty sources Iike the vertical angular deviation of photometer calibration benches, in order to define criteria to its quality assessment.
