E27 screw ceiling fan, 20.5 inches, 40 W, with dimming function via remote control.

Includes a socket extension: Installation is incredibly simple; just screw the fan bulb into the socket – no complicated wiring is required. Plus, we include a 3.81-inch (9.7 cm) socket extension for easy installation of the fan bulbs in recessed fixtures. The socket is made of flame-retardant material, making it heat-resistant and durable. New memory function: The fan socket remembers the color and brightness from the last use and restores them for the next use, for added convenience. No more frequent adjustments. Note: Please use the ceiling fan remote to turn the light on and off. Fan speed and intensity: You can use the remote to control the light's color temperature and the fan speed. Adjustable intensity from 2700K to 6500K, with three fan speeds (low, medium, and high) to suit your needs. You can also choose to turn the light on only or the fan simultaneously. Versatile applications: Our remote-controlled ceiling fan with integrated light is ideal for compact spaces requiring good air circulation, such as garages, kitchens, storage rooms, balconies, attics, laundry rooms, closets, dining rooms, workspaces, basements, sheds, utility rooms, etc."
