xenon lamp
This beam of xenon is a high-intensity light source producing a wide spectrum of light that closely resembles natural sunlight.

Those quite literally put into typical xenon lamps inside testing and simulation just for the aspect that it's really light exposure for metals and others alike.

Key Features:

  • Principle of Operation: Contains xenon that, when electrically energized, emits intense white light covering UV, visible, and infrared wavelengths. Usually used in a controlled environment to apply tests for sun exposure lasting a number of hours.
  • Properties Measured: Color fading, surface degradation, oxidation, and material durability under very intense lighting conditions. Helps in assessing the resistance of a certain material under UV exposure and thermal effects.
  • Different applications: It's used in weathering tests, material durability and photochemical research. It is important in the automotive industry, aerospace, coatings, plastics, and textiles concerning quality and product development.

A xenon lamp is important in the sense that, how sunlight is created in the real world, it can also be manipulated in a controlled laboratory to produce the same sunlight exposure and then predict on how they would behave in extreme lighting conditions.
