What kind of light is used in a woods lamp?

A woods lamp utilizes filtered black light to produce its illuminating effect. The specific type of light is crucial because a woods lamp is typically used in skin analysis to diagnose various skin conditions. The filtered black light allows for the examination of the skin under ultraviolet light, which can reveal conditions that are difficult to see under regular light.

The filtered aspect of the black light specifically helps in reducing the glare and enhancing the visibility of certain skin types and conditions, such as fungal infections, pigmentation issues, and even the presence of certain oils and debris on the skin.

This function of the woods lamp is essential in skin care and esthetics, as it promotes an accurate diagnosis and effective treatment planning. Other types of lighting, such as incandescent, LED, or fluorescent, do not provide the same specific benefits in examining skin under ultraviolet rays, making filtered black light the appropriate choice for this purpose.
