Understanding UV Wavelengths

The two most common ultraviolet black light wavelengths are 365nm and 395nm.

365nm UV

365nm produces ultraviolet light that is almost invisible to the human eye. Because there is less visible purple light, fluorescent materials stand out much more brightly.

Advantages

• Strong fluorescence
• Better contrast
• Ideal for professional inspections
• Preferred for industrial use
• Better for detecting invisible markings

Typical applications

• Security marking verification
• Forensic inspection
• Leak detection
• Mineral identification
• Fluorescent dye inspection
• Laboratory work

395nm UV

395nm emits more visible violet light. Although fluorescence is slightly less intense than 365nm, these lamps are generally more economical and work well for decorative lighting.

Advantages

• Brighter visible output
• Lower cost
• Excellent for entertainment
• Good for fluorescent decorations

Typical applications

• Glow parties
• Halloween decorations
• Escape rooms
• Home theatres
• UV artwork
• Fluorescent posters
