1. Product Overview
The SANSI 28W Motion Sensor Outdoor Security Light (Model C2440-GW) is designed to provide bright, energy-efficient illumination for outdoor spaces. Featuring a 28W LED light source with 3500 lumens, this hardwired floodlight includes a motion sensor and offers four distinct operating modes. Its robust IP65 waterproof construction ensures reliable performance in various weather conditions, making it suitable for soffit, garage, and yard installations.
Key features include:
- High Brightness: 28W, 3500 lumens, equivalent to 350W traditional lighting.
- Advanced Motion Sensing: Detects motion up to 72 feet with a 120° detection angle.
- Four Operating Modes: Auto (Motion Sensor), Dusk to Dawn, On-Time, and Test Mode.
- Durable Construction: IP65 waterproof rating and high-quality polycarbonate (PC) material for weather resistance.
- Efficient Heat Dissipation: Patented ceramic temperature control system extends lifespan.
- Adjustable Design: 180° adjustable light heads and sensor head for optimal coverage.
2. Safety Instructions
Please read and understand all instructions before installation and use. Retain this manual for future reference.
- Electrical Safety: Always turn off power at the circuit breaker before installing or servicing the fixture. Improper wiring can result in electric shock or fire.
- Qualified Electrician: If you are unsure about the installation process, consult a qualified electrician.
- Grounding: Ensure the fixture is properly grounded to avoid electrical hazards.
- Mounting Surface: Mount the fixture securely to a stable surface that can support its weight.
- Operating Temperature: Do not operate the light in temperatures outside its specified range.
- No User-Serviceable Parts: Do not attempt to disassemble or repair the light fixture. This will void the warranty.
- Avoid Direct Eye Exposure: Do not stare directly into the LED light source when it is illuminated, as this may cause eye strain or damage.

- Mounting Plate
- Mounting Screws and Wall Anchors
- Gasket
- Wire Nuts
- Instruction Manual
4. Installation Instructions
This light can be mounted on a wall or under an eave/soffit. Follow these steps for proper installation:
- Prepare for Installation: Turn off power at the circuit breaker. Ensure the junction box is ready for mounting.
- Secure Mounting Plate: Fix the mounting plate to the junction box using the provided screws.
- Connect Wiring: Connect the electrical wires by color: black (hot) to black, white (negative) to white, and green (ground) to green. Use wire nuts to secure connections.
- Mount the Fixture: Turn the fixture upside down and screw it into place on the mounting plate.
- Adjust Light Heads: Once installed, adjust the light heads to direct illumination as needed.
- Position PIR Sensor: Rotate the PIR sensor down and outward. Ensure the light heads are facing upwards and the sensor is oriented downwards. This helps minimize interference from ambient light and optimizes sensor performance.

5. Operating Modes
The SANSI motion sensor light offers four selectable operating modes:
- Mode 1: AUTO (Motion Sensor Mode): The light automatically turns on for 1-10 minutes at night when motion is detected.
- Mode 2: Dusk to Dawn Mode (D2D): The light automatically turns on at dusk and turns off at dawn, remaining on continuously during the night.
- Mode 3: On-Time Mode: This mode allows for manual control via a switch, functioning like a standard light fixture.
- Mode 4: Test Mode: In Test Mode, the light turns on for only 5 seconds whenever motion is detected, regardless of ambient light conditions (day or night). This mode is useful for verifying sensor functionality and coverage during installation.

6. Adjusting Settings
The motion sensor has adjustable dials for LUX (brightness sensitivity), Time (duration the light stays on), and Range (motion detection distance).
- LUX (Brightness Sensitivity): This dial sets the ambient brightness level at which the sensor activates. A high LUX setting means the light will stay on constantly if the environment is bright enough, while a low LUX setting may cause flashing. It is recommended to set the LUX dial to the halfway point for optimal performance.
- Time (Duration): This dial controls how long the light remains on after motion is detected, typically adjustable from 1 to 10 minutes.
- Range (Detection Distance): This dial adjusts the maximum distance at which the sensor will detect motion, up to 72 feet.

7. Maintenance
To ensure optimal performance and longevity of your SANSI outdoor security light, follow these maintenance guidelines:
- Cleaning: Periodically clean the light fixture and sensor lens with a soft, damp cloth to remove dirt, dust, or debris. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect the wiring and mounting for any signs of damage, corrosion, or loose connections. Address any issues promptly.
- Sensor Obstructions: Ensure that the motion sensor is not obstructed by plants, branches, or other objects that could interfere with its detection capabilities.
- No Bulb Replacement: The LED light source is integrated and not user-replaceable.
8. Troubleshooting
If you encounter issues with your SANSI motion sensor light, refer to the following common problems and solutions:
- Light Flashes Continuously or Stays On in Auto/D2D Mode:
Solution: Check the LUX setting. A high LUX setting can cause the light to remain on constantly, while a very low setting might cause flashing. Adjust the LUX dial to the halfway point for optimal performance. - Light Does Not Turn On:
Solution: Ensure the power supply is active. Check the circuit breaker. Verify all wiring connections are secure. Confirm the LUX setting is appropriate for the ambient light conditions (e.g., not set too high during daylight hours). - Motion Sensor Not Detecting:
Solution: Ensure the sensor is not obstructed. Adjust the sensor head and light heads to cover the desired area. Increase the 'Range' setting on the sensor. Test in 'Test Mode' to confirm basic sensor functionality. - Light Turns On Randomly:
Solution: This can be caused by environmental factors such as moving branches, small animals, or heat sources within the detection zone. Adjust the 'Range' setting to reduce sensitivity or reposition the sensor to avoid false triggers.
