I’ve got one of these bulbs, and SmartThings seems to identify it as a Zigbee RGB Bulb which means none of the dimming functionality works - only the on/off.
This is the GU10 version. Has anyone had joy with this?
Just as a quick curious question (sorry to get your hopes up!) what’s the beam angle on these?
36 degrees 
I’ve fixed it now anyway. Added an OSRAM Lightfy custom device type from on here, added the bulb as the Zigbee Hue (as it shows up) and then changed the device type online
