FAQ
- What is CCT?
-
The Color Correlated Temperature level (CCT) is given in the description of each of our white led bulbs. The color (CCT) of our white bulbs ranges from a warm yellow white (2700K) to a cool blue white (7000K).
By comparison, a typical incandescent bulb has a CCT of 2800K. A common halogen is a bit higher, possibly 3500K. Daytime white is 4500K and a cool white fluorescent is 6000K or more.
The human eye adapts to background light so that even a daytime white bulb could look somewhat blue in a space brightened primarily with incandescent bulbs. Likewise, an incandescent bulb will certainly look really yellow and even orange in midday sunlight.
