Sengled Boost Wi-Fi Repeater LED Bulb: Enjoy smart lighting and extend your wireless network with a single device. The 7.5W LED bulb delivers warm white illumination with a 3000K color temperature. You can control lighting by downloading the iOS and Android app. Plus, the bulb works with 802.11b/g/n 2.4GHz networks and supports WPA/WPA2-PSK and WEP security.
This is a great little product as long as you understand what it is and how it works. It is a wifi extender/repeater with a mobile app controlled light. The extender works like a champ, I used it to add signal to my home theater and game systems. You have to download an easy to use app (for Android or IOS) you can dim and turn the light off and on from the app, and only the app. The bulb needs to be on at all time, and not on a dimmer.
Sadly I had to return it only because my router was the problem.
