Yesturday I bought the new IKEA Trådfri smart bulb and remote. Trådfri just launched on selected markets (Sweden, Czech Republic, Italy and Belgium) and will roll out further in April 2017. There are different variants but all can both dim light strength and warmth (http://www.ikea.com/se/sv/search/?query=tr%C3%A5dfri), are very affordable and has a very high quality feel.
The solution runs on zigbee light link ZLL, same as Philips Hue and I managed to connect the bulb to Smartthings using a Hue device handler and it works perfectly. Since I bought a bulb+remote kit, I also tried to connect the remote. I managed to get the get the hub to recognize the remote as a zigbee button device but the hub does not receive any button events, the only thing I managed to receive was the battery status of the remote.
