By reading this I dont really think you understand the terms with lighting. Spectrum has absoulutely nothing to do with lumens. 6500k is on the cold side of the light spectrum and has a high amount of "blue" in its spectrum. 2700k is pretty much the exact opposite. 2700k is on the warm side which is the "red" end of the spectrum. The colder u go on the spectrum the more your light will appear to be white and warm side makes it appear yellow. Lumens is a measurement of how bright the light is.
