Not quite, There is alot on wikipedia that helps eplain lumens and kelvin. One analogy that helpd me under stand limens and why you cant simply add all the numbers was...

Picture a room with only 1 light bulb in the center and a door that is only open a crack. Turn the light on and note the light comeing out the crack..now add 1 more light bulb and look at the light comeing out the door, it will be brighter but not 2x as bright.

google image search kelvin temp. and the charts will help. Basicly the numbers do not just add up but you are on the right track!!

Good Luck
