Buying Guide
What to consider when choosing a black light inspection lamp
- Wavelength and purpose: 395 nm is common for urine and stains, while other wavelengths may be marketed for novelty or curing tasks. Choose based on stains you expect to detect and whether resin curing or counterfeit detection is needed.
- Power source and run-time: Determine if you prefer disposable battery models (AA/AAA) or USB-C rechargeable designs for frequent use and reduced waste.
- Beam size and portability: A broader beam covers larger areas, while a compact pen-style light excels for spot checks and tight spaces.
- Durability and form factor: Look for pocketable, clip-capable units for hands-free use in field inspections or travel.
- Accessories and compatibility: Some kits include multiple units or belts/clips; consider whether you need a second unit for partners or for travel.
Practical tips for use
- Work in darker environments to maximize fluorescence visibility.
- Test on a cleaned surface first to understand baseline fluorescence.
