I used this in my living room for about two years, but I'm selling it due to a move. As you can see in the 7th photo, there is a small scratch. It doesn't affect the lighting, and it's not visible from below. This product itself is a SwitchBot hub, making it a convenient product for building a smart home. The following specifications are extracted from the website where I purchased it: Brand: SwitchBot Product Model Number: ‎W2612240 Product Size: ‎39 x 39 x 9.6 cm; 1.1 kg Color: Stepless brightness and color temperature adjustment Family Name on Sign: Alexa compatible Material: SPCC|Acrylic Voltage: ‎110 volts Light Source: LED Other: ‎Energy saving, 5-year warranty, stepless dimming and color temperature adjustment
