1. Introduction
This manual provides detailed instructions for the safe and effective use of your FAISHILAN 4-Pack LED Black Light Bar. Please read this manual thoroughly before installation and operation, and retain it for future reference.
The FAISHILAN LED Black Light Bar is designed to produce ultraviolet (UV-A) light, which causes fluorescent materials to glow brightly. It is suitable for various applications including stage lighting, parties, and artistic displays.
2. Important Safety Information
- Electrical Safety: Ensure the power supply voltage matches the product's requirements (110 Volts). Do not operate with damaged cords or plugs. Disconnect power before cleaning or servicing.
- UV Light Exposure: While this product emits UV-A light (385-400 nm), which is generally considered safe for short-term exposure, prolonged direct exposure to UV light can be harmful to eyes and skin. Avoid staring directly into the light source.
- Waterproof Rating: The product has an IP65 waterproof rating, meaning it is protected against dust ingress and low-pressure water jets. It is suitable for outdoor use but should not be submerged in water.
- Ventilation: Ensure adequate ventilation around the light bar to prevent overheating. Do not cover the light bar during operation.
- Installation: Install the light bar securely using the provided brackets. Ensure the mounting surface can support the weight of the unit.

5. Setup Instructions
- Unpack: Carefully remove the black light bars and all components from the packaging.
- Choose Location: Select a suitable location for installation. Consider the desired illumination area and the proximity to a power outlet. The IP65 rating allows for both indoor and outdoor use.
- Mounting:
- The light bars come with pre-attached adjustable brackets.
- Use appropriate screws or mounting hardware (not included) to secure the brackets to a wall, ceiling, or other stable surface.
- The brackets allow for 180° rotation, enabling you to adjust the light direction. Loosen the screws on the side of the bracket, adjust the angle, and then tighten the screws to secure the position.
- Connect Power: Plug the power cord into a standard 110V AC power outlet. Ensure the ON/OFF switch on the cord is in the "OFF" position before plugging in.

6. Operating Instructions
- Power On: Once securely mounted and plugged in, flip the ON/OFF switch on the power cord to the "ON" position. The LED black light bar will illuminate.
- Optimal Effect: For the best fluorescent glow effect, use the black light bar in a dark or dimly lit environment. The UV-A light will react with fluorescent materials, causing them to emit visible light.
- Power Off: To turn off the light bar, flip the ON/OFF switch to the "OFF" position. For extended periods of non-use, it is recommended to unplug the unit from the power outlet.

7. Maintenance
- Cleaning: Disconnect the power before cleaning. Use a soft, dry cloth to wipe the surface of the light bar. Do not use abrasive cleaners or solvents, as they may damage the finish or LED components.
- Storage: When not in use for extended periods, store the light bar in a cool, dry place, away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the power cord and housing for any signs of damage. If damage is found, discontinue use and contact support.
