Get mixed set (different color temperatures)

I ordered ordered neutralweiß (4500K) with a set 5x9W Spots. Receive Although I have spots, but unfortunately not in a uniform Farbtemparatur but with three different (warm, neutral, cold). Because I wanted to use the lamps in a lighting strip ceiling with 5 spots, that was very natÃ'rlich Ã'rgerlich and the lights went on the VerkÃ'ufer zurÃ'ck (smooth handling).

Apart from that, the luminous efficiency fÃ'r seemed the 9W given too low. I deliver in this house almost exclusively LED lamps and sport in action, all a better light output with partially reduced consumption.
