I've tried a few LED lamps and got stuck in this OSRAM. She has a very good light output and is the traditional halogen lamp in every way, even from the light color of her. After I bought the end of December 20 of which I had so far been three total failures recorded. The lamps should replace the old halogen energy guzzlers in two waiting rooms and burn 10 hours a day (the electronic transformer was also newly built), but now has 3 lamps are defective. These are only briefly when turning, then it hisses short and they go out again. Angrily that is after such a short time already, especially if you look at leaves on such big brands as Osramt. Apparently the electronics are overwhelmed for increased uptime and any component inside the lamp dies the heat death.
