Abstract
This paper presents a comparison of two different methods for the realization of the SI unit of luminous intensity, the candela. A measurement system has been set up at IEN for comparing results obtained by a standard ECAR technique with those based on the work of Ikonen et al. on trap detectors. The paper highlights some of the problems encountered; preliminary results show that the agreement between the two methods is within the declared uncertainty and suggests promising areas for future works.
