I have read many reports in advance and looked at many products. Because I wanted to have a replacement for my 20W halogen bulbs, the decision is then dropped on the LED's. Actually, I would have liked to buy bulbs with a color temperature of 2700K, but somehow it does not seem to be possible in this case. I at least have not found any. Full of expectation, as "cold" these lamps then ultimately seem I unpacked and replaced these. Unfortunately, I was but then bitterly disappointed. Things are hotter than the existing halogen lamps, which would not necessarily bad, but the other having a terrible greenish tint. To use the lamps in the kitchen should come under the wall cabinets, but with this green light is not that. These lamps go back clearly. 2 things I can not understand the basis of the problem. There are on the one hand, today in most cases even the color value specified as a number. If you then look at various lamps one realizes that the color temperature differs greatly, although it is at all, for example, 3000K. Here it must be reminded of their duty manufacturers times to indicate correct values. What should because the customer otherwise judge them? On the other hand I have read many reviews and only one has also written that these bulbs have a greenish tint. Is this really noticed anyone else?
