JARLSTARSmart Recessed Lighting with Junction Box 4 Inch RGB LED Recessed Lights WiFi Smart Retrofit Downlight Dimmable 9W 600LM 3000K-6500K Selectable, Compatible with Alexa/Google, 4 Pack

Easy to Install and wifi is working good, I've 10 months using it and no problems yet.

To connect this light required disabling 5Ghz and ONLY have 2.4GHz on my router (a pain by itself) in order to connect and even then it was very finicky. Finally did get connected, only to have it eventually lose connection. This happened several times over a few days, and just was not reliable. This is the only smart light/device that I have which had this connectivity issue, other lights (from other vendors) were easy to connect and have stayed connected consistently. I even sent an email to the support address listed and never received a response. I would not recommend this "smart" light at all.

The light works so good

I was able to connect and set up fine. Within a couple of hours a few lights disconnected and wouldn’t reconnect. Needed to go through the hole set up again and again. Finally thought I had it. Then lights turned on for no reason. I had the lights now for 2 weeks and they still go offline and don’t connect.Very disappointing. My 2.4 WiFi is very good and shouldn’t be the problem. It might be because I have to many. I have 16 between to rooms back to back.I probably wouldn’t recommend if you need a large amount of them.
