After I experienced a letdown with another LED G4, I have ordered these here and am satisfied. Due to the low Bauhähe and not so large diameter, they fit both in a Miele extractor that was originally equipped with halogen, and in my Covo halogen spotlights substructure under the kitchen cabinets. After the conversion there was no hum of transformers and no flickering. The light is actually warm white, in my view. The light intensity could indeed be slightly higher, but is ok. In this respect there is a clear recommendation from me, especially because of the fit, the pleasant light and because they do not buzzing!
