ALONEFIRE SV84 365nm UV Flashlight – 45W Black Light for Pet Urine Detection, Resin Curing, and More

Powerful 365nm UV illumination for fluorescence tasks

The ALONEFIRE SV84 UV flashlight delivers a bright, focused 365nm beam designed for precision in homes, workshops, and field environments. With four 4-core UV LEDs, it can draw up to 45W of power and produce around 8000 mW of luminous flux, helping you reveal fluorescence that may be hard to see with the naked eye.

To ensure a purer ultraviolet output, the unit is equipped with a hard, crack-resistant black filter lens. This filter minimizes ambient light interference, helping you spot subtle glows more clearly during inspections or creative projects. The sturdy aluminum alloy body supports reliable heat dissipation, which can extend lamp life during extended sessions.

Smart power and safety features

Charging is simple with USB-C, and a dedicated indicator keeps you informed of the power status. The package includes four starter batteries to get you started, with a recommendation to consider higher-drain cells for longer professional use between charges.

• 4x 4-core UV LEDs and up to 45W power
• 8000 mW luminous power for strong fluorescence visibility
• USB-C rechargeable with charging indicator
• Hard black filter lens for purer UV output
• Aluminum alloy shell for heat dissipation and durability
• UV protective glasses included for safer viewing

Real-world uses and applications

In everyday environments, this flashlight helps reveal things not always visible under standard lighting. It can assist with pet urine detection on fabrics and floors, enhance resin and glue curing workflows, and support fluorescence-based checks in minerals, scorpions, and other materials. It is also suitable for quick currency authentication and bed bug inspections when used responsibly.

• Pet urine detection on carpets, fabrics, and surfaces
• Resin curing and glue setting with visible fluorescence cues
• Scorpion, mineral, and currency detection in various settings
• Bed bug and other fluorescence-assisted inspections

Safety and preparation for use

Always avoid direct eye exposure to strong UV light. The included UV protective glasses are designed to help reduce glare and improve comfort during prolonged sessions. When not in use, store the device with the lens cap and keep charging indicators monitored for optimal uptime.
