So i was checking out some lightbulbs a while back and i noticed they had these numbers on it. One type had the number... it was like 3100K and the other was 5500K or so. Are these the temperatures corrposponding to the blackbody radiation associated with those temperatures? I know there's 2 types of lightbulbs generally... the whiteish type (or well, i mean the color of light given off) you see in offices and the yellowish you see at home. Now the thing is... the whiteish type... i thought white light was just the combining of light? How could it have a temperature associated with it? Any help on all this would be .. helpful :D Plus does anyone know which, the 3100K ish or the 5500K ish will produce the normal home-type yellow light?
