After I put it to the test I was severely disappointed by the SAATLY downlight .The only pro was that it had adjustable settings, but the cons were plentiful. The Bluetooth connectivity was weak and often disconnected, and the quality of the light was poor with a harsh yellow tint at 2700K and an overly bright, blueish-white light at 5000K. Its "industrial electrical" designation is laughable as it would never hold up in a true industrial setting. Stay far away from this product..
