Kelvin to the light temperature of the light rays not the lumens of light output. 6000 kelvin is a blueish white appearing light and yes it appears somewhat very white but a single 921 LED has a quite low lumen level output. I have two LED 921'a in our range hood and it's just enough light to see clearly what's cooking 18" below. Perhaps a gang of 921's would broadcast enough light to actually see the black 5th wheel hitch 4 feet behind by using a shiny cone shaped reflector. Gobs of possibilities can be experimented with. Who knows, might come up with a real novel idea or even a patentable idea. Yankee ingenuity at work...
