This light bulb I have recently bought the. Had me before the description read to find out what this light bulb is really her. At home I have the light bulb that can be like a "normal light bulb" substituted tried the same. These dimmable nine watts IWY Light is really great. Every minute the color of light can be changed. I was amazed that it actually works even with the remote control and the iPhon. Energieeffizientzklasse A is for a light bulb in my opinion quite well. Now I wonder, equip the other two rooms with these bulbs, they come but a sixty watt bulb equal. First, you can change the colors for his "feeling" and secondly, it certainly looks good too, if in any room A Different Light "shines". Although they are in the purchase of not cheap, but by dimming saves quite a bit and it pays off in the end.
