   en.wikipedia.org/wiki/Fluorescent-lamp_formats

   Fluorescent lamps in various embodiments. Since their introduction as a commercial product in 1939, many different types of fluorescent lamp have been introduced. Systematic nomenclature identifies mass-market lamps as to overall shape, power rating, length, color, and other electrical and illuminating characteristics.

3. Standard illuminant - Wikipedia

   en.wikipedia.org/wiki/Standard_illuminant

   The spectrum of a standard illuminant, like any other profile of light, can be converted into tristimulus values. The set of three tristimulus coordinates of an illuminant is called a white point. If the profile is normalized, then the white point can equivalently be expressed as a pair of chromaticity coordinates.

4. Lighting - Wikipedia

   Color temperature for white light sources also affects their use for certain applications. The color temperature of a white light source is the temperature in kelvins of a theoretical black body emitter that most closely matches the spectral characteristics (spectral power distribution) of the lamp. An incandescent bulb has a color temperature ...

   Color rendering index (CRI) is an attempt to measure the ability of a light source to reveal the colors of various objects faithfully in comparison to a black body radiator. Colors can be perceived using light from a source, relative to light from a reference source such as daylight or a blackbody of the same color temperature. By definition ...

6. List of colors by shade - Wikipedia

   en.wikipedia.org/wiki/List_of_colors_by_shade

   White is the lightest color and a balanced additive combination of all the colors of the visible light spectrum, or of a pair of complementary colors, or of three or more colors, such as additive primary colors. It is a neutral or achromatic color (without chroma), like black and gray

7. Color temperature - Wikipedia

   The house above appears a light cream during midday, but seems to be bluish white here in the dim light before full sunrise. Note the color temperature of the sunrise in the background. Video camera operators can white-balance objects that are not white, downplaying the color of the object used for white-balancing. For instance, they can bring ...
