1. Introduction
The wolezek Red Light Therapy Bulb is designed to provide targeted red light and near-infrared light therapy. It features 18 high-power LEDs, combining 9 LEDs emitting 660nm deep red light and 9 LEDs emitting 850nm near-infrared light. This combination is optimized for various applications including skin care and pain relief. The bulb is designed for easy home use, fitting standard E26 or E27 sockets.

2. Safety Information
- Eye Protection: Always use appropriate eye protection (such as sunglasses or a sleeping mask) when using the red light therapy bulb, especially when treating areas near the face.
- Heat: While the bulb is designed for efficient heat dissipation, avoid prolonged direct contact with skin to prevent discomfort.
- Placement: Due to the bulb's weight, it is recommended to use it with a sturdy floor lamp or a robust clamp lamp, not a clamp lamp with a gooseneck arm, to ensure stability and prevent accidental falls.
- Voltage: Ensure the bulb is used with a 100-240V AC power supply.
- Medical Advice: This device is for general wellness and pain relief. Consult a healthcare professional for specific medical conditions or before starting any new therapy.
3. Setup
- Unpack: Carefully remove the red light therapy bulb from its packaging.
- Choose a Lamp: Select a lamp with a standard E26 or E27 socket. A sturdy floor lamp is recommended due to the bulb's weight. Avoid gooseneck clamp lamps that may not support the bulb securely.
- Install Bulb: Screw the wolezek Red Light Therapy Bulb into the lamp socket until it is firmly seated.
- Position Lamp: Place the lamp in a stable position where it can safely direct light to the desired treatment area.
- Connect Power: Plug the lamp into a suitable 100-240V AC power outlet.

4. Operating Instructions
- Turn On: Activate the lamp using its power switch.
- Positioning: Position the bulb 6 to 12 inches away from the target treatment area.
- Treatment Duration: Use for 10-20 minutes per session. The frequency can be 2-14 times per week, depending on individual needs and comfort.
- Eye Protection: Always wear eye protection during use, especially when treating facial areas.
- Target Areas: The bulb is suitable for targeting areas such as the face, shoulders, knees, and waist for skin care and pain relief.

5. Maintenance
- Cleaning: Ensure the bulb is unplugged and cool before cleaning. Gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners or immerse the bulb in water.
- Storage: Store the bulb in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Inspection: Periodically inspect the bulb and its connections for any signs of damage. Discontinue use if any damage is observed.
6. Troubleshooting
- Bulb Not Lighting Up:
- Ensure the lamp is securely plugged into a working power outlet.
- Check if the lamp's power switch is in the 'on' position.
- Verify the bulb is screwed in tightly into the socket.
- Some LEDs Appear Dim/Off:
- The 850nm near-infrared LEDs are invisible to the naked eye. It is normal for only half of the LEDs (the 660nm red ones) to appear illuminated. This does not indicate a malfunction.
- Bulb Feels Heavy/Unstable:
- The bulb has a solid aluminum body for better heat dissipation, making it heavier than standard bulbs.
- Always use with a sturdy lamp base or clamp that can safely support its weight. Avoid gooseneck clamp lamps.
