The results have been compared to the information declared by the manufacturer on the energy efficiency label and the product fiche. The measured electric power input of the lighting System and the measured grease absorption factor often differed significantly from the declared values. The reasons for these observations and the necessary steps to ensure accurate measurements and a meaningful EU energy efficiency label are elucidated. It is suggested that the ranges of the lighting efficiency classes are readjusted to fit the nowadays prevalent LED technology. Furthermore the tolerance in the regulation for the nominal electric power input of the lighting could be extended by a minimum absolute tolerance. The grease absorption test method may need a rework to achieve a satisfying accuracy.
