The LED lamps have a pleasant mood light, but for my dimmer Busch - Memory touch dimmer 6560 unsuitable, this I learned after my return order from the manufacturer. Nice Contact'll retain the LED lamps and me a new set Dimmer "Eltako - UC to 400 W Multifunction - Universal - - EUD 12 NPN". I hope this investment is worth it for the conversion of a 2-burner dining hanging lamp of 60 W incandescent bulbs to LEDs 9W.
