lumens is light output (e.g. brightness) and color temperature in K is the coloration.
THey have nothing to do with each other (on the first order scale anyway), they're independent specifications of different attributes of a light source.
there's some interaction as you change the voltage the brightnes changes and the coloration will too. But usually they are specified at the intended operating voltage of 115 volts.
as for color temp, i think the lower values in the 2700-3500 range are warmer (more red) and the values in the 4000-5000 range tend to be greener or bluer.
