I prefer the 3k models as they give close to the incandescent color everybody want and still high lumen output. The 2700k is not as bright and the 3600k and 4k make you feel like your in a office. This is a great model and is what I have installed in my house. http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053 I have installed more expensive models but the main factor to look for is CREE technology.
