Ultraviolet light, or UV light, is a commonly used term for ultraviolet radiation, although it is not actually light.
Ultraviolet light, often abbreviated UV light, is a commonly used everyday term for ultraviolet radiation. Strictly speaking it is not light at all, since light refers to the visible portion of the electromagnetic spectrum and ultraviolet wavelengths are too short to be seen by the human eye. The term persists because ultraviolet radiation behaves in many ways like visible light and is produced by lamps that resemble lighting fixtures.
Despite the name, ultraviolet light is invisible electromagnetic energy with more energy than visible light. It is used in applications such as fluorescence, sterilization, and curing, and its presence in sunlight is what degrades unprotected materials outdoors.
In commercial and industrial settings, ultraviolet light is relevant both as a tool and as an environmental factor that can degrade cable. Recognizing that the term refers to ultraviolet radiation helps in understanding its effects and uses.

At Windy City Wire, an understanding of ultraviolet exposure supports the selection of cable suited to its environment. Recognizing how ultraviolet, whether called UV light or radiation, can degrade unprotected materials helps customers choose sunlight-resistant cable for exposed commercial and industrial installations.
