This paper will present preliminary results from a research project comparing two methods for estimating the lifetime of LED products, LM-84 (6000 h test) and the new EU endurance test (3600h test) including on/off cycling, that will be required by EU from 2021. Beside the luminous flux development for the sources tested, their colorimetric results will also be examined as a function of time. Preliminary results for two series of LED products will be presented. For one series, the 3600h test have been completed, for the remaining series only results from the 6000h test is available. Results of the luminous flux and colour maintenance will be presented. Initial examinations shows good agreement between the two tests methods for the first series of LED products measured.
