This 42-inch indoor ceiling fan features a refined steel structure combined with five smooth blades, integrating both mechanical design and aesthetic appeal. It effortlessly enhances the style and atmosphere of various spaces. The lighting system is equipped with a 18-watt Led light source, offering 3 levels of precise color temperature adjustment - 3000K warm white for a relaxing atmosphere, 4000K neutral white for daily lighting, and 6000K cool white for reading scenarios. It also has a memory function, allowing for the long-term preservation of personal preferred lighting settings without the need for repeated adjustments. The core component is a Dc bidirectional motor, which not only operates silently and without disturbance but also can achieve bidirectional rotation: in summer, it rotates forward to deliver cool air, and in winter, it rotates backward to circulate the indoor warm air. It is practical throughout the year.
