Thank you for viewing. This is a Ceiling Light Pro for 6 tatami mats. It's new, but I damaged the cover, so I bought a new one and am now selling this one. It works perfectly fine. This can remotely control TVs and air conditioners, and can be operated from the SwitchBot app. You can find out how to use it by searching online. The damaged part is about the size of a thumb. Smart function equipped ceiling light, 36W LED lighting. - Brand: SwitchBot - Model Name: Ceiling Light Pro - Features: Smart Light & Smart Remote 2-in-1 - Color: White - Power Consumption: 36W - Light Source: LED
