Too bad, I had very happy with this but mostly well-rated LED bulbs our current consumption of the mirror light in the bathroom to reduce drastically. So far did there 4 Osram 33W G9 bulbs their service. It was a nice surprise as I had installed the new SMD LEDs. The light was almost as bright as before. That is now almost exactly 4 weeks. For about a week, the light is so dark, as if we had placed two candles. In addition, yesterday began even to one of the bulbs, in between to flicker. For us, this means that while we save electricity, but would have to replace 4 bulbs every three weeks. Priced at 6.99 per bulb per year which are approximately 485 interfaces. This product I can not recommend as sustainable unfortunately. Pity!
