Philips Hue White & Color Ambiance Smart Retrofit Recessed Downlight 4", Color Changing, Bluetooth & Zigbee Compatible (Hue Hub Optional), Smart Ceiling Lighting These Phillips hue lights are decent and well made. The retrofit option is superb especially for my house that had legacy potlight fixtures. The app itself is well developed and clean bug free interface. Bluetooth connects just fine. This one can set infinite colors. Controlled by app. With latest firmware update , you can setup the bulb to default turn on with a specific color and brightness, or a scene. Therefore when you turn he switch off and on again, it restores your preferred default settings. You can also just enable " last used setting " as well. These are by default Bluetooth only. And will only connect from app to bulb when the switch for the bulb is ON. Otherwise if the switch is off, the app disconnect. There are optional accessories by Phillips to add on a hub system but this is not part of this review. Install is a cinche. It should easily fit a typical 4" housing. Remove old light and screw in this one. That's it. Overall a very nice Eco system. It's costly though but quality is excellent. There are no name knock offs out there for a fraction of the price of Philips hue system.... But I'm personally not a fan of many of them because of the strange app and shady permissions you have to give the app (like contacts). Philips only requires permission for Bluetooth connectivity which makes sense. Hope this helps.

I wish they made these in a 6in but I was able to use my old 6in light and add the housing onto this and glue it together. All in all, very easy to use, very easy to install, and seems high quality. I just wish it was like 20% brighter.

Love these Philip Hues lights, easy to install and provide a lot of good entertainment and ambiance to the house. So much so we were replaced every light in the house to Philip Hughes 70+ all working easily on our Wi-Fi system. My only negative, the price. Other than that you’ll really enjoy them and all the apps made around them for you to use

I have this with my other Philips lights that I have in the house. Works as advertised

These are a must if you have a sync box with recessed light areas to put these. They make a big difference.
