- CCT
CCT stands for Correlated Color Temperature. The Color Temperature of a light source indicates the specific
color of light that a black body radiator emits at a given physical temperature. As the temperature of a black
body radiator increases, the hue shifts from yellow-orange, to white, to blue. The sun and an incandescent bulb
are examples of black body radiators. LED are not thermal radiators (that is, the light that is emitted is not a
direct consequence of the material temperatures, but of the physics of semiconductors) thus the correlated color
temperature of an LED correlates the color of the LED to the color of a black body radiator at a given temperature.
The units of color temperature is Kelvin. The color temperature of a tungsten incandescent bulb is 3200K.
The color temperature of the sun is 5600K.
The CCT measurements for various Manfrotto products is shown below.
Due to peculiar condition of the manufacturing process of LEDs, the optical and electrical parameters may vary
significantly among chips of the same production batch.
In order to guarantee a perfect light uniformity, all products belonging to Manfrotto Spectra range embed LEDs
with selected and precisely controlled color bins. All values are measured at typical ambient temperature of 25°C.
