Yes, you can easily find them on Amazon, https://smile.amazon.com/SYLVANIA-Changing-Equivalent-SmartThings-Assistant/dp/B0197840KQ/ref=sr_1_9?ie=UTF8&qid=1548692257&sr=8-9&keywords=osram+lightify
And yes I use them with robots and shortcuts to change the colors.
Did a little looking following your idea, I looked for Hue alternatives that work with the smartthings hub, and found this. The bulb may still be a bit expensive at $40USD, but that's $10USD cheaper than the equivalent Hue bulb, and with the Sylvania bulb, I don't need a special hub just for the lights.
