Thermal illumination dating of pottery
We further find that the delayed off-time signal in time-resolved IRSL has immense potential for sampling non-fading signal and should be explored further; this signal also appears to be well reset in nature and avoids unwanted thermal transfer effects in comparison to the post IR-IRSL signal measured at 290 degrees C.
The most important functions are as a holder for the light source, to provide directed light and to avoid visual glare.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 of the lamp.Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight.Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings.

Recessed lighting (often called "pot lights" in Canada, "can lights" or 'high hats" in the US) is popular, with fixtures mounted into the ceiling structure so as to appear flush with it.
