Q: What do "cool white" and "warm white" mean, and what is CCT?
A: The Color Correlated Temperature (CCT) is given in the description led ligh/ lamp/bulbs.By comparison, a typical incandescent bulb has a CCT of 2800K. A typical halogen is a bit higher, maybe 3500K. Daylight white is 4500K and a cool white fluorescent is 6000K or more.

The human eye adapts to background light so that even a daylight white bulb will look slightly blue in a room illuminated mainly with incandescent bulbs. Similarly, an incandescent bulb will look very yellow or even orange in midday sunlight.
