The black lights we handle have relatively little impact on the human body and use wavelengths near UVA!
Visible light, which can be seen by the human eye, appears in various colors depending on the length of its "wavelength." The wavelength of light that is visible to the human eye ranges from approximately 400nm to 750nm. In contrast, wavelengths below 400nm, which cannot be seen by the human eye, are referred to as "ultraviolet light," meaning light beyond violet. Therefore, while black lights may not seem to emit much light to the human eye, they actually produce a significant amount of "invisible light." Ultraviolet light affects the human body depending on its wavelength, but the black lights we handle emit relatively low levels of impact on the human body, utilizing wavelengths in the UVA range (365nm to 405nm) that are commonly used in industrial applications. *For more details, please refer to the PDF materials or feel free to contact us.*

basic information
**Types and Dangers of Ultraviolet Rays** ■UVC - Wavelength of 200–280nm - Particularly strong effects on living organisms among ultraviolet rays - This wavelength is used in sterilization lamps, etc. ■UVB - Wavelength of 280–315nm - Sunburns, commonly known, occur specifically within this wavelength range - Prolonged exposure to the skin can cause adverse effects such as inflammation ■UVA - Wavelength of 315–400nm - Prolonged exposure to the skin causes gradual damage - Although it feels dark due to low visibility, it emits strong light similar to regular white LEDs - Direct viewing is dangerous *For more details, please refer to the PDF document or feel free to contact us.*
