Review on 🔆 Smart WiFi Recessed Lighting, 5/6 inch Retrofit Ceiling Down Light with RGBCW Multicolor, Compatible with Alexa/Google, 2700K-6500K Color Changing Can Light Bulb (1 Pack) by Amy Cummings

They are not a set of 4 that can be combined and used in sync with the music. 👎 - The brightness is only brightest in white, all other colors look good but not as bright as you can see in the pictures even if you set it to 100% 👎 - The app has many options but could be more user-friendly.👎 - It works well with Alexa, Google Home but not Siri, remember this is specially for us Apple fanatics. 👎 - Don't expect help from support, they will redirect you to a seller you've never had met can connect here👎 - Once you lose wifi, they will lose their brains. Mine started turning on and off randomly.
