2. Color temperature - Wikipedia

   en.wikipedia.org/wiki/Color_temperature

   An incandescent lamp's light is thermal radiation, and the bulb approximates an ideal black-body radiator, so its color temperature is essentially the temperature of the filament. Thus a relatively low temperature emits a dull red and a high temperature emits the almost white of the traditional incandescent light bulb.

3. Template:Color temperature scale - Wikipedia

   Color temperatures and example sources Temperature Source 1700 K Match flame, low pressure sodium lamps (LPS/SOX) 1850 K Candle flame, sunset/sunrise: 2400 K Standard incandescent lamps: 2550 K Soft white incandescent lamps 2700 K "Soft white" compact fluorescent and LED lamps 3000 K Warm white compact fluorescent and LED lamps 3200 K

4. Full-spectrum light - Wikipedia

   en.wikipedia.org/wiki/Full-spectrum_light

   Color emitted by a black body on a linear scale from 800 kelvins to 12200 kelvins. The emission spectrum of a light source varies depending on the light generating mechanism. Thermal sources such as incandescent bulbs produce electromagnetic radiation over a broad and continuous range of wavelengths, including infrared and ultraviolet.

5. These are the best — and worst — lightbulbs for the planet

   Over a decade, the original incandescent bulb and its replacements will cost about $93, whereas over the same stretch of time, that LED bulb will cost $19.45 — as just one LED bulb can last up ...

6. Color rendering index - Wikipedia

   en.wikipedia.org/wiki/Color_rendering_index

   Researchers use daylight as the benchmark to which to compare color rendering of electric lights. In 1948, daylight was described as the ideal source of illumination for good color rendering because "it (daylight) displays (1) a great variety of colors, (2) makes it easy to distinguish slight shades of color, and (3) the colors of objects around us obviously look natural".

7. Architectural lighting design - Wikipedia

   en.wikipedia.org/wiki/Architectural_lighting_design

   The color temperature of a white light source is the temperature in kelvin of a theoretical black body emitter that most closely matches the spectral characteristics of the lamp. Incandescent light bulbs have a color temperature around 2700 to 3000 kelvin; daylight is around 6400 kelvin. Lower color temperature lamps have relatively more energy ...

   Only roughly 5% of the energy used by an incandescent bulb produces light; the remaining 95% or so is lost as heat. This is why you let an incandescent bulb cool off before unscrewing it.
