I paid for the repair of the kitchen, where 4 such lamps were installed. One died 12 months later. The second died in 18 months. I can't tell if they simply blew (and if so, did I get part of the claimed service life) or if another component in the unit failed. A few weeks before they go out completely, they finally light up if you keep turning the light on and off. I'm sticking with them for now so all the lights are the same but if the other one fails I'll probably replace them all with a different manufacturer.
