With regard to the light power of the light color and the dimensions of these lamps are very good. The light has a surprisingly warm tone. In direct comparison with a halogen bulb in my opinion a slightly greenish tint is visible, but which does not really bother. The brightness (5.5W) is subjectively comparable to a 35W halogen bulb. The dimensions are very compact for a G9 LED bulbs fit into lamps with shade. For me, these LED lamps are the first real alternative to G9 halogen bulbs in terms of size and light output. Unfortunately, they produce a clearly perceptible hum during operation. Especially in lights with metal housing this sound is further enhanced, however, it is perceived in each lamp and disqualified this bulbs - in my opinion - for use in residential areas.
