3 Smart Lighting Modes: Our solar security lights provide bright illumination with 800 lumens. They feature three easy-to-switch modes: (1) Smart Sensor Mode (automatically turns on when movement is detected at night, then dims to constant brightness); (2) Sensor-Only Mode; (3) Dim Constant Bright Mode. [Important Note] Press the white button to switch modes. For first-time use, charge in direct sunlight for 6-8 hours to fully activate the battery. Three Adjustable Colors and USB Backup Charging: Choose from cool white (brightest), neutral (natural), or warm white (cozy) light to perfectly complement your garden, patio, or path. [Troubleshooting Tip] If using a USB cable (included), ensure you use a 5V/2A adapter (not included) for optimal performance. Solar panels are always the preferred charging method. Multi-functional Clip Mounting and Secure Fixation: These innovative solar lights come with a sturdy built-in clip for easy mounting on fences, patios, or tables. No tools required! Also includes screws and clear adhesive hooks for permanent wall mounting, allowing for flexible application to most surfaces. Ideal for patio use. Suitable for porches, garages, and backyards. Built-in clips securely hold on surfaces no thicker than 2.55 inches (6.5 cm) - please check your surface dimensions before purchasing. IP65 Waterproof & ABS Material: This outdoor solar light is made of high-strength ABS material for durability. Its IP65 waterproof rating reliably withstands rain, snow, and high temperatures. [Please Note] This product is designed to be weatherproof and waterproof; do not immerse in water. Dimensions: 3.8 inches (L) x 3.9 inches (W) x 6.8 inches (H). Sensitive Motion Sensor: Equipped with a sensitive PIR motion sensor, it can detect moving objects up to 26 feet (8 meters) away within a 120° angle. 【Key Installation】For optimal performance, it is recommended to install at a height of 5 to 8 feet (1.5 to 2.4 meters) and ensure the solar panel faces the sun. How to test the light at night or indoors: (1) Simulate a dark environment: To test the motion sensor or night function, you must (1) completely cover the solar panel with your hand or an opaque object (e.g., a box) to simulate a night environment; (2) Avoid light interference: Ensure the light fixture is not installed near other light sources (e.g., porch lights, streetlights), otherwise the solar light may fail to turn on automatically, resulting in a misjudgment of a malfunction. Keep away from other light sources. Otherwise, the solar light may not function properly. For optimal performance, a full charge requires 6-8 hours of direct sunlight (solar charging) or approximately 4 hours of USB charging. Note that reduced sunlight in winter may affect charging efficiency and overall performance.
