Not as expected, much too dark.

In a classical piano piece two lamp "fitted" very light yellowish but not unpleasant. The first two or three days they were still relatively light (not as bright as the zuvorigen 20 W Halogenbirnchen, they guess at perceived 10-15 W in direct comparison), the luminosity but within a month now (although all SMD lights still lit) to more than 50% decreased, the light has become even yellower and unfortunately no longer be used as a replacement for halogen lamps. A flickering or buzzing, I can not determine. Due to the many other positive reactions, I expect to have a "Monday Model" caught.
