77outdoor SF16 365nm UV Flashlight – Rechargeable Tail Switch

Reveal the unseen with 365nm UV clarity

The 77outdoor SF16 delivers a focused 365 nm ultraviolet beam that reveals fluorescence where the eye alone can't reach. When operating in High mode, the flashlight outputs about 875 mW, and a dedicated filter lens helps fluorescence pop in dim spaces, making faint traces on carpets, fabrics, and other surfaces easier to spot. Fluorescence is strongest around 360 nm, so this setup is designed to highlight subtle stains or residues that might otherwise go unnoticed, especially in low-light environments.

Power and control are designed for everyday use. The SF16 recharges via USB Type-C, allowing quick top-ups without the need to replace batteries. The tail switch is shaped for one-handed use, and the intuitive UI lets you cycle through modes with a soft, almost silent click, helping you stay focused on the task at hand rather than the device.

Rugged, ready for real-world use

Durability matters when you’re chasing hidden details. The SF16 features an aerospace-grade aluminum alloy body paired with a high-strength tempered glass lens. An IPX-8 rating ensures resilience against water exposure and immersion during field checks, DIY projects, or busy household use. The compact, palm-friendly form supports comfortable handling in a wide range of situations.

• Compact, ergonomic design enables easy one-handed operation
• Robust construction resists bumps and daily wear
• IPX-8 rating provides dependable water resistance

Practical, day-to-day applications

Beyond detecting pet urine traces, the 365nm beam illuminates fluorescent agents, cosmetics residues, currency features, and certain documents that glow under ultraviolet light. It can assist with low-light passport or ID checks and other quick verification tasks, offering a visual aid without promising guarantees.

• Detect pet urine stains on carpets, rugs, and upholstery
• Reveal fluorescent agents, cosmetics residues, and currency markers
• Support low-light checks of documents and IDs
