Magnetic Alignment Design: The lamp base and ball are attracted by magnetic force, no locking is required. The" two point positioning "magnetic design uses the same principle of polar repellent to ensure that the sensor is always at the front. Gravity Aesthetics: The rotating design of the base is based on the principle of gravity: even if the lamp ball is glued as you like, it can return to vertical after automatic adjustment, while maintaining an angle vertical like drops of water. Soft Warm Color: 6 warm color LED lighting units are used in combination with the frosted spherical design to avoid direct light. Therefore, the light is generally soft and fuzzy and is distributed in the night light. It is a pleasant light that people can enjoy at night. Day and night support: four to six months standby waiting to wake up at any time. Built-in rechargeable polymer battery. Under normal use, it can last 4-6 months on a single charge and be bright for 20 hours. Attention to detail: Rechargeable design, environmental protection and avoid battery replacement. The three-level switch and micro USB charging port utilize the "invisible design" hidden in the base interface taking into account the integration of appearance and convenience. Smart sensor. Detection range available: 0-3m and 120 degrees.The effective detection range is 0 to 3 meters in front of the sensor. In 120 fan-shaped zone detection mode, it will automatically turn on for 20 seconds after being watched by someone (continuous activation) if no activity is available in the detection zone, 20 seconds after lighting. The night light turns off automatically. Technical specifications : 3 level buttons: Auto / OFF / ON. Input voltage: USB 5V. Power: 0.25 W. Charging port: micro USB. Automatic lighting time: 20 s.
