Unfortunately very loud and not warm!

Because unfortunately the light is super brightly, the light beam is white and utterly cold even for the kitchen. I will now attempt to glue the bulb forward where the light exits with tracing paper. Does not look accurately grade and chic, but gets the job done and that's light now warmer than before a lot!

Otherwise, I think, are all the other positive and negative points already elsewhere (+ of course especially in the item description, the yes in terms of energy efficiency fully applies).

Set When this light bulb (regardless of whether LED or not) wished to place, then not push in by force, but the two "nipple" below the base as in the text: For those who have first chewed a lamp it GU10 socket that they are going into the two holes provided, then just turn the bulb clockwise by about 90 degrees and it will snap into place.
I not aware that at first, so it was for the sake of completeness written here simply times :)

Because of the uncomfortable light, the lamp casts, only 3 ***!
