What Colour temp is daylight?
5000K-6500K
Color temperature is measured in Kelvin (K), and there are three common ranges: Warm Light (2700K-3000K); Cool White (3000K-5000K), and Daylight (5000K-6500K).
Is D65 a 6500K?
D65 is a particular embodiment of the D series of illuminants defined by the CIE, and has a color temperature of approximately 6500K.
Are LED lights better than fluorescent?
LEDs are very efficient relative to every lighting type on the market. Most values for LED system efficiency fall above 50 lumens/watt. Fluorescent and CFL lights are very efficient compared to incandescent lights (50-100 lumens/watt source efficiency).

What kind of light source is cool white?
A, which represents an incandescent or tungsten light source (2856° Kelvin) found in the home. F2 (also called F, F02, Fcw, CWF, CWF2), which represents the spectral quality of the most common fluorescent lamp—cool white fluorescent—found in office environments.
What is the temperature of a F11 light source?
F11 represents a narrow tri-band fluorescent of 4000° Kelvin color temperature, CRI 83. White light sources and their corresponding illuminants usually have correlated color temperature (K) and color-rendering index (CRI) values associated with them. White light sources vary from warm white to cool (blue) white.
Is there such a thing as a light source?
A: Yes, there is! By the term “light source” we describe any object that emits “light” (relative energy distribution in the visible spectrum app. 380 – 750nm). The quality and energy of this light is not described and can vary; sunlight for example will vary in its appearance during the day and time of year as well as with the weather.
