Specified by the manufacturer 50.000 operating hours are unfortunately a pure fantasy figure! Already after one month operation (lamp in the anteroom, daily. About 4 hours operating with about 15 switching processes) must replace the first lamp. The lamp even had burn marks on the LEDs! Now after about a month have again need to change the exchanged lamp because this was already defective. Stay away from this crap !!! The conventional halogen lamps used in the same fitting comply already much longer its purpose.
