1. Introduction
Thank you for choosing the LUXON 5W E26 Radar Motion Sensor LED Light Bulb. This product is designed to provide convenient, energy-efficient lighting with advanced radar motion detection and dusk-to-dawn functionality. Please read this manual carefully to ensure proper installation, operation, and maintenance.
2. Product Features
- Radar Motion Sensor: More sensitive and penetrating than traditional infrared sensors, detecting motion through glass, veneer, and thin walls.
- Dusk-to-Dawn Functionality: Automatically turns on only in dark or dim light conditions when motion is detected.
- Automatic On/Off: Lights up upon motion detection and turns off automatically after approximately 30 seconds of no motion.
- Wide Detection Range: Detects motion within 13-19 feet (4-6 meters).
- Energy Efficient: 5W LED replaces 50W incandescent bulbs, saving over 90% on electricity.
- Long Lifespan: Approximately 20,000 hours of operation.
- Soft White Light: 2700K color temperature for a warm and inviting ambiance.
- Standard E26 Base: Easy installation into common light sockets.

4. Setup and Installation
Follow these steps for safe and effective installation:
- Power Off: Before installation, ensure the power to the light fixture is turned off at the circuit breaker to prevent electrical shock.
- Insert Bulb: Screw the LUXON motion sensor bulb into a standard E26 light socket. Ensure it is securely tightened.
- Positioning: The bulb should be installed downward and no higher than 10 feet (approximately 3 meters) for optimal motion detection.
- Avoid Enclosed Fixtures: Do not install the bulb into an enclosed fixture or one with a clear glass cover. This can significantly reduce the motion detection radius and interfere with the radar sensor's performance.
- Power On: Restore power to the light fixture. The bulb will initially light up for 40-60 seconds regardless of motion. This is a normal initialization period.

5. Operating Instructions
The LUXON motion sensor bulb operates automatically based on ambient light and motion detection:
- Dusk-to-Dawn Operation: The bulb will only activate in dark or dim light conditions (below 5-10 lux). It will not turn on during daylight hours, even if motion is detected.
- Motion Detection: When the ambient light is low enough, the bulb will turn on automatically if it detects motion within its 13-19 feet range. The radar sensor can detect movement through certain non-metallic obstacles.
- Initial Power-On: Upon first installation or after a power cycle, the bulb will remain lit for 40-60 seconds regardless of motion. This is normal.
- Auto-Off Function: If no further motion is detected within the sensor area, the bulb will automatically turn off after approximately 30 seconds.
- Continuous Lighting: If continuous motion is detected within the sensor area, the bulb will remain lit until motion ceases.

6. Maintenance
The LUXON LED motion sensor bulb requires minimal maintenance:
- Cleaning: Ensure the bulb is cool and power is off before cleaning. Gently wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Handling: Handle the bulb by its base to avoid touching the glass surface, which can leave residues.
- Storage: If storing the bulb, keep it in its original packaging in a cool, dry place.
7. Troubleshooting
If you encounter issues with your LUXON motion sensor bulb, refer to the following common solutions:
- Bulb does not turn on:
- Check if the power to the fixture is on.
- Verify that the bulb is screwed in securely.
- Ensure ambient light conditions are dark enough for the dusk-to-dawn sensor to activate.
- Confirm motion is occurring within the 13-19 feet detection range.
- Check if the bulb is installed in an enclosed fixture or behind a thick glass cover, which can impede radar detection.
- Bulb stays on continuously:
- During the first 40-60 seconds after initial installation or power-on, the bulb will stay lit. This is normal.
- Ensure there is no continuous motion within the detection range. The bulb will remain on as long as motion is detected.
- Check for environmental factors like swaying branches or small animals that might be triggering the sensor.
- Bulb turns on during the day:
- The ambient light sensor may be obstructed or in a shaded area, causing it to perceive darkness. Relocate the bulb or clear any obstructions.
- Reduced detection range:
- Ensure the bulb is installed downward and not higher than 10 feet.
- Avoid installing in enclosed fixtures or behind clear glass covers, as this can significantly reduce the sensor's effectiveness.
- Obstacles like thick walls or metal objects can block radar signals.
