Which type of light is effective in detecting pet urine contamination?

Ultraviolet light is particularly effective in detecting pet urine contamination due to its ability to cause certain substances, like those found in urine, to fluoresce under its rays. When urine is exposed to UV light, it often shows a characteristic glowing appearance, which can be especially helpful for technicians in identifying areas of contamination that may not be visible under normal lighting conditions. This capability allows for a more thorough assessment when performing odor control and cleaning procedures.

Other light types may not possess this specific property. For instance, halogen and xenon lights emit visible light but do not have the same fluorescing effect on organic materials like urine. LED lights are versatile and energy-efficient, yet they also lack the UV spectrum necessary to reveal the fluorescence of pet urine. Therefore, ultraviolet light stands out as the optimal choice for detecting pet urine contamination effectively.
