Reference from Amazon below: Price: 24,008 yen Brand: AONCIA Color: White Design: Ceiling fan Power Source: Electric Style: Casual Product Dimensions: 40D x 40W x 18.5H cm [Lighting + Ventilation in One - Light Guide Plate - Easy Installation] AONCIA's next-generation ceiling fan light, LumaFlow, combines lighting and ventilation, delivering both light and wind. It brightens and comforts your room from above, creating a healthy indoor environment. Unlike regular lighting, it uses an acrylic light guide plate, which emits a beautiful light like Saturn's rings when lit. Also, it's a hook-on ceiling type, so you can quickly and easily install it by checking the wiring fixture. [High Color Rendering - 10-Step Color/Brightness Adjustment - Night Light Mode] It uses high-quality LED chips, emitting a beautiful glow and creating a vibrant space. You can choose from three color temperatures: daylight, daylight white, and warm white, depending on the installation location. You can adjust the color temperature to your preferred lighting mode from 6500K to 2700K in 10% increments, and adjust the brightness of the LED lighting in 10 steps of 10% each. You can use it according to the scene. With a maximum of 4160lm, it can adequately illuminate a room of 8-10 tatami mats. Also, for those who don't like a completely dark environment when sleeping, and for children or nighttime nursing, you can enable the night light mode. [8-Step Airflow Adjustment - Rhythm Wind - Swing Function - Swivel] Equipped with a high-performance DC motor, it allows for 8-step airflow adjustment. You can freely adjust the airflow from a comfortable breeze to a powerful strong wind, depending on the environment. The energy-saving rhythm wind, which is close to natural wind, lowers the airflow to a level below the set airflow level at set intervals, adding fluctuations to the airflow to reduce power consumption and save energy. Also, the fan can be adjusted at a 15-degree angle, and the swing function allows it to swivel, rotating 360 degrees to deliver wind over a wide area. [Air Circulation Mode - Reverse Rotation - Temperature Difference Equalization] You can change the airflow direction using the remote control. It changes from the conventional downward airflow to airflow from the floor to the ceiling, enabling air circulation within the room. The reverse rotation of the fan draws cold air upwards and promotes warm air from above downwards, reducing the temperature difference between the upper and lower parts of the room, creating a more comfortable space.
