The brightness of a light is measured in lumens, not in color temperature (K). However, 6000K light appears cooler and whiter, while 4000K appears warmer and more yellowish. If both bulbs have the same lumens, neither is inherently "brighter," but 6000K may seem brighter to the eye because of its cooler tone.
