ALONEFIRE SV84 365nm UV Flashlight – 45W USB-C Black Light for Urine Detection & Resin Curing

Overview

The ALONEFIRE SV84 is a high‑performance 365nm UV flashlight crafted for real‑world inspection, detection, and lightweight curing tasks. With a formidable 45W power draw and up to 8000 mW of luminous output, this compact tool delivers bright, focused ultraviolet light where you need it most. A hard, black filter lens helps suppress ambient glare, revealing fluorescence with greater clarity in dim or cluttered environments. The combination of a heat‑dissipating aluminum alloy shell and thoughtful design means you can work longer with confidence, whether you’re at home, on the job, or in the field.

Core technology and construction

Inside the SV84 sits four 365nm UV LEDs configured for strong, even illumination. The result is a reliable beam that makes fluorescent signals pop, from pet urine traces to resin indicators. The sturdy aluminum body acts as an efficient heat sink, helping preserve the LED life during extended use. A dedicated UV filter lens enhances light purity by filtering out stray environmental light, so you can see contrasts more clearly.

• Four 4‑core 365nm UV LEDs for powerful, even light
• Hard, toughened black filter lens to deepen fluorescence visibility
• High‑quality aluminum alloy shell for heat management and durability

Ease of use and safety

Rechargeability is simple with USB‑C, and the SV84 includes a charging indicator so you know exactly when it’s ready. A pair of UV protective glasses is included to provide safer viewing during UV work, and four starter batteries are supplied for immediate use on the go.

• USB‑C recharge with a clear charging indicator
• Included UV protective glasses for safer operation
• 4× standard starter batteries included

Versatile applications

Designed to reveal fluorescence that isn’t visible to the naked eye, the SV84 suits a broad range of tasks. It’s well suited for pet urine detection, scorpion spotting, mineral and currency checks, and bed bug detection. It also serves as a practical tool for curing resins and setting glues, making it a flexible asset for hobbyists and professionals alike.

• Detects fluorescent substances not visible to the eye
• Pet urine detection and scorpion spotting
• Mineral inspection and currency feature verification
• Resin curing and glue hardening

With its combination of bright UV output, robust build, and user‑friendly features, the SV84 is positioned as a capable companion for inspection, detection, and light curing tasks where UV insight matters—while keeping expectations measured and grounded in real‑world use.
