4. Safety Information
To ensure safe operation and prevent injury or damage, please observe the following precautions:
- UV Exposure: Avoid direct and prolonged exposure to the UV light. While the 395-400 nm wavelength is generally considered safe for human and pets, prolonged direct exposure to any UV light can be harmful to eyes and skin.
- Heat Generation: The black light generates heat during operation. Ensure adequate ventilation around the unit and avoid placing it near flammable materials. Do not touch the light surface when it is operating or immediately after turning it off.
- Electrical Safety: Use only with a compatible AC110V power supply. Do not modify the plug or cable. Ensure the power cord is not pinched or walked on.
- Waterproof Rating: The unit is IP66 waterproof, suitable for outdoor use in rain or snow. However, do not submerge the unit in water.
- Placement: Place the light on a stable surface or mount it securely. Keep out of reach of children and pets to prevent accidental contact with the hot surface.
5. Setup
The Glostars 100W LED UV Black Light is designed for easy installation without complex wiring.
- Unpack: Carefully remove the black light units and accessories from the packaging.
- Placement: Choose a suitable location for the black light. The integrated 360-degree adjustable stand allows for flexible positioning on flat surfaces or for mounting. Ensure the light is directed towards the area where fluorescent effects are desired.
- Connect Power: Plug the 1.5m power cable into a standard AC110V electrical outlet.
- Activate: Use the inline push-button switch on the power cable to turn the light ON or OFF.

6. Operation
Once set up, the Glostars 100W LED UV Black Light is ready for operation. The light emits UV-A at 395-400 nm, which causes fluorescent materials to glow brightly.
- Turning On/Off: Use the switch on the power cord to control the light.
- Effectiveness: For best results, use the black light in a dark or dimly lit environment. The UV light will cause reactive pigments, paints, and dyes to fluoresce, creating a vibrant glow effect.
- Applications: Ideal for black light parties, Halloween decorations, Christmas lighting, clubs, aquariums, body art, and theatrical performances.

8. Troubleshooting
If you encounter issues with your Glostars 100W LED UV Black Light, refer to the following common solutions:
- Light Not Turning On:
- Ensure the power plug is fully inserted into a working electrical outlet.
- Check the inline switch to confirm it is in the 'ON' position.
- Test the outlet with another device to ensure it is receiving power.
- Light Gets Warm During Use:
- It is normal for the unit to generate heat during operation due to its high power output. The aluminum alloy body is designed for effective heat dissipation.
- Ensure the light is placed in an area with good airflow and not enclosed, to aid in cooling.
- Avoid prolonged direct contact with the light surface during and immediately after use.
- Insufficient Glow Effect:
- Ensure the environment is sufficiently dark for the UV effect to be visible.
- Verify that the materials you are trying to illuminate are indeed fluorescent or UV-reactive.
- Adjust the distance and angle of the light to optimize coverage and intensity.
