Osram/Sylvania makes one. This bulb connects directly to SmartThings, you do not need their gateway.
That said, there is a known issue with this brand where if your network is busy, it will identify itself is a zigbee repeater to your hub but it may lose some of the messages it is given to repeat, kind of like a buffer overflow situation.
Whether or not this is a problem really depends on whether you have others zigbee repeaters nearby and of course whether you have zigbee battery powered devices trying to use a repeater.
Some people find they don’t have any problems with these bulbs on their network, others have found they needed to remove them or they were continually losing messages from their nearby sensors.
The Hue bulbs connected through the hue bridge do not have this problem.
