## Description

The Alonefire SV52 is a 25W 365nm UV torch designed for tasks that need a strong and focused ultraviolet beam, from pet stain detection to resin curing and mineral inspection. It offers a robust output while remaining compact enough for field work and hobby use.

## Key features

This torch uses a single-core 365nm UV LED rated at up to 25W, delivering intense UV illumination according to the manufacturer. A hardened black filter lens reduces visible light contamination to produce a cleaner ultraviolet beam, which helps when pinpointing urine stains, checking scorpion reflections or speeding up small-area resin curing. The aluminium alloy body improves heat dissipation, supporting sustained output during longer sessions, and the kit includes a rechargeable high-capacity battery and USB Type-C charging for convenient top-ups on the go. For safety, UV protective glasses are supplied and should be worn while operating the torch.

## Specifications

- Name: Alonefire SV52
- Type: UV torch
- Wavelength: 365nm
- Power: 25W
- Colour: Black
- Format: USB rechargeable

## Usage tips

Use the torch in a dim or dark environment to make UV reflections and fluorescence easier to spot, and allow a few seconds for the beam to stabilise after powering on. For resin curing, keep the light moving slowly across the area rather than holding it in one spot to reduce local heat build-up. Remember that the unit is powerful and direct eye exposure must be avoided, so fit the supplied protective glasses before switching on.

## What’s included

The pack contains the Alonefire SV52 torch, a rechargeable battery, USB Type-C charging cable and UV protective glasses. The battery supports the high-power output stated by the manufacturer and is intended to provide practical runtime for typical hobby and inspection tasks.

It’s a good fit if you need a portable, high-output 365nm light for inspections, crafting or outdoor checks, but bear in mind that strong UV requires cautious handling and proper eye protection.
