UV-A Blacklight: Unveiling the Versatility of Ultraviolet-A Spectrum (UVA)

UV-A, a crucial part of the ultraviolet spectrum, serves as the foundation for numerous applications that extend well beyond mere novelty. Commonly known as blacklights, these specialized UV bulbs find their utility in various fields. While frequently utilized in stage and studio setups, their significance goes beyond entertainment, encompassing practical applications such as currency fraud detection, identification validation, and even tracking the path of bedbugs by identifying organic waste.

In both commercial and residential settings, UV-A light bulbs (UVA) are commonly found in insect traps and bug zappers, owing to their ability to attract many flying insects, which are naturally drawn to ultraviolet light.

While UV-A light may possess some germicidal effectiveness over extended periods, its disinfection power remains relatively limited. For humans, it generally poses little danger, except when exposed to high dosages.
