The Mengs LED bulbs fit very well into the G9 holder. Light color and intensity are super. The light corresponding to the color of her almost exactly the halogen bulbs used previously (G9 40W). The brightness of the LEDs is a little higher.
A buzzing sound - to read as with many other LED lamps in the recession - I hear not here.
Conclusion: absolutely recommendable LED lamp, which I have ordered today more directly.
