If you wanted to match your Low beam or your angel eyes that match stock lights you should have purchased 4300K. The LED kelvin temperature is likely accurate but as the above poster mentioned the refraction through the angel housing tones down the blue making it look like a warm white.
HPB service is top notch by the way.
Their phone system is down due to hurricane Irene apparently so that explains the phone thing, and I have to agree about the service, I finally received an email today and they are very quick at responsing and it seems like they really care.
