I've found the temperature accuracy listed for a bulb varies depending on the quality of the bulb, at least here in the US. I'm in the process of replacing 50-60 par30s halogens (downlights) and while the 3000k Cree bulbs are twice the price (and weight) of some alternatives, they are a perfect replacement for the halogens. If anything the art on the wall below the LEDs look better than when under the halogens too somehow.
