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 polar repelling principle to to guarantee that the sensor is always at the front. Aesthetics of gravity : the rotating design of the base is based on the principle of gravity: even if the lamp ball is stuck as you like, it can return to vertical after automatic adjustment, while maintaining a vertical angle like drops of water. Therefore, the light is usually soft and hazy and is distributed in the night light. It is a pleasant light that people can enjoy at night. Support day and night : standby four to six months 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 luminous for 20 hours. Attention to detail : rechargeable design, environmental protection and avoid battery replacement. The three-level switch and USB charging port use the invisible design hidden in the base interface taking into account the integration of appearance and convenience.
