TORCHSTAR 6 Inch LED RGBCW Smart Recessed Lighting with J-box for Kitchen, Living Room, Dimmable Color Changing Warm & Cool White, 12W Wi-Fi Smart Downlight, Pack of 4

I purchased two sets of 4 lights each. One star was removed because one of them was missing blue, but the vender's customer service responded reasonably quickly , and areturn is in process. The other 7 are installed and work great. Pros: They are brighter than expected. 7% brightness is enough in most cases. I followed their spacing recommendations. Being able to turn these off and on through an app saved me installing wall switches, and has many advantages. The 7 are in the ceiling of our living room. There is one swatch in an unrelated room's closet (necessary for their setup). They are able to be placed under the floor joists so placement looks perfect. The they style or temperature of the light can be adjusted to your taste 2000-5000K. They are efficient and the LEDs last a vary long time. If on at 100% at 5000k in white mode, you would probably need sunglasses. There are no hums or buzzes from these lights. Cons: I couldn't (easily) use my smart phone to set these up because my phone uses 5G channels to connect to the wifi; so I had to dig out an old phone that connected to 2.4G wifi so each light's controller could be given the house wifi password. Once each light is connected I could use and control them with my newer phone. It wasn't easy to group these lights together with the app. I was able to make one touch buttons to turn them all on, all off, etc. I still am not able to get all 7 lights to respond to music at the same time. Only one at a time. They interfere with my over the air (OTA) TV reception. I can get VHF digital channels 2 (8 channels) and 6 (3 channels) only when the 120v AC power to the lights is off. If the lights are off but still connected to the wifi these channels don't come in. ---To sum up. I am happy with these lights and would recommend them.
