Lots of light with little electrical energy

I repeatedly tried energy-saving replacement for my lamps with GU10 sockets in recent years and placed because of the small amount of light again disappointed aside. With this being valued product I have taken a new approach. At Amazon.com you can well guided by the reviews. In addition, the provider of this LED spotlight has made a clear indication of the expected amount of light. I ordered 10 pieces. 9 pieces are in use. I am very pleased with the luminosity. That's why I forgive also 5 star. Nevertheless, everyone should take care that the light cone is much wider than conventional halogen lamps (120 ° as described). This creates a very different light impression. Even the already excessive proportion of yellow is described in the light. I can confirm that. It is not a simple shift of the color temperature in the sense of warm tone or light, but really too much yellow portion. The use of eg the vanity mirror is therefore not recommended. Thanks again to the other reviewers without whom I would not have chosen this product.
