Setup and Installation
Follow these steps for optimal performance and secure installation:
- Choose a Location:
- Select a location for the solar panel that receives at least 6-8 hours of direct sunlight daily. Avoid shaded areas.
- Mount the light unit in the desired area (e.g., yard, garage, driveway, porch) ensuring the motion sensor faces the area you wish to monitor.
- Mount the Solar Panel:
- Using the provided screws and wall anchors, securely mount the solar panel in your chosen sunny location. The 15-foot cable allows flexible placement.

This image highlights the generous 15-foot cable connecting the solar panel to the light unit, providing ample length for optimal solar panel placement in direct sunlight, even if the light unit is mounted in a shaded area.
- Mount the Light Unit:
- Attach the light unit to the wall or eave using the appropriate mounting hardware. Ensure it is firmly secured.
- Connect the solar panel cable to the light unit's input port.

This diagram illustrates the recommended installation process, showing how to mount both the solar panel and the light fixture on a building. It emphasizes ensuring the motion sensor faces outwards when mounted on an eave for proper detection.
- Adjust Light Heads:
- Manually adjust the three light heads to direct illumination where needed.
Operating Instructions
The LEPOWER Solar Security Light features a stepless adjustable switch for controlling its operational modes and motion sensor sensitivity.

Figure 6: Control Switch and Modes
This image details the control switch on the motion sensor, showing the three operational modes: Test Mode, Auto Mode, and Normally On Mode, along with their respective indicators and functions.
Operational Modes:
- Test Mode:
Quickly adjust and test the light before final installation. In this mode, the light turns on for approximately 7 seconds when motion is detected, regardless of ambient light conditions (day or night). This is useful for verifying sensor coverage.
- Auto Mode:
This is the primary operational mode for security lighting. The light will automatically turn on at night or in dimly lit environments when motion is detected. It will stay illuminated for a duration adjustable between 10 seconds and 120 seconds (maximum) after the last detected motion. The light will turn off when no motion is detected within the set time frame.
- Normally On Mode:
Push the switch to "ON". In this mode, the solar motion light will remain continuously illuminated for approximately 50 minutes after being fully charged. This mode is suitable for situations where continuous light is desired for a period, such as during an outdoor gathering.
Adjusting Motion Sensor Sensitivity:
The motion sensor features a stepless adjustable switch to customize the sensing distance from 0 to 72 feet. Rotate the dial to increase or decrease the detection range according to your needs. A wider detection angle of 180° ensures comprehensive coverage.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your LEPOWER Solar Security Light:
- Clean the Solar Panel:
Periodically wipe the solar panel with a soft, damp cloth to remove dust, dirt, leaves, or snow. A clean panel ensures maximum sunlight absorption and efficient charging.
- Clean Light Heads and Sensor:
Gently clean the LED light heads and motion sensor lens with a soft, dry cloth. Avoid abrasive cleaners that could scratch the surfaces.
- Check Connections:
Occasionally inspect the cable connection between the solar panel and the light unit to ensure it is secure and free from damage.
- Battery Care:
The light uses integrated Lithium Ion batteries. While designed for long life, ensure the solar panel receives adequate sunlight to keep the batteries charged. Prolonged periods without charging can reduce battery lifespan.
