This work has studied the probabilistic risk analysis at the time of making a declaration of conformity on the technical performance of a luminaire. The luminaires under test are LED luminaires, since LED technology has a growing development and currently these luminaires are the most used for public lighting worldwide. There are a large number of manufacturers and therefore, it is necessary to verify the quality of the luminaires that are marketed; for which, it is required that a conformity assessment body (OEC) certifies that the technical characteristics of the luminaires comply with regulations. For this study, the parameter to be analyzed is the power, the OEC is a testing laboratory that is accredited with ISO/IEC 17025, and under which performs the declaration of conformity; the power value is obtained during the execution of luminous intensity matrix tests. The power measurements have been evaluated under a parametric statistic and it has been obtained that for confidence levels lower than 99.99% the recorded power of the luminaire is compliant, and for confidence levels higher than 99.998% the result is non-compliant with the experimental scheme used.
