5. Operating Instructions

5.1 Power On/Off and Mode Switching

• To turn the flashlight ON, press the button on the tail cap.
• To switch between 365nm UV light and 395nm UV light, lightly press the tail cap button again while the flashlight is on.
• To turn the flashlight OFF, press the tail cap button firmly until it clicks.

5.2 Adjustable Focus (Zoom Function)

The flashlight features a telescopic adjustable focus, allowing you to change the beam from a wide floodlight to a narrow spotlight.

• To zoom in (narrow beam/spotlight), pull the head of the flashlight outwards. This concentrates the light for more precise detection.
• To zoom out (wide beam/floodlight), push the head of the flashlight inwards. This spreads the light to cover a larger area.

6.1 Understanding 365nm vs. 395nm UV Light

The DARKBEAM flashlight offers two distinct UV wavelengths for different detection needs:

• 365nm UV Light: This wavelength is closer to true UV and is often referred to as "invisible UV." It causes fluorescent materials to glow brightly while the surrounding area remains dark, making the fluorescent object stand out clearly. It is ideal for detecting fluorescent agents, authenticating documents, and inspecting amber or jewelry.
• 395nm UV Light: This wavelength produces a visible purple glow. It is brighter and has a farther illumination range, making it suitable for general detection of pet stains, scorpions, and other fluorescent substances where a visible light component is acceptable.

7. Maintenance

• Cleaning: Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Keep the lens clean for optimal performance.
• Storage: Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.
• Water Resistance: The flashlight has an IPX4 waterproof rating, meaning it is resistant to splashing water from any direction. It is not designed for submersion.
