The lamp has a diameter of 250mm, and I stand away from the ceiling at 71mm. It is made of SPCC steel sheet, with anti-corrosion coating. Dedicated to rooms below 10m2. The light color is 5700k, and the power is 670 lm. The lamp has no communication with the Xiaomi smart home system, it can not be controlled remotely. Only works on the motion sensor.
The Yeelight sensor with motion sensor has been priced in China on 99 yuan, $ 15 and it is an adequate price for such a product. The lamp can be bought on a popular website AliExpress.but its price is already over $ 35. Similar lamps are available in Poland for a decidedly lower price, closer to the market price in China or $ 15. If someone is looking for such a product, I recommend looking around the local market.
