Difference between lightstrip and lightstrip 1S?

The title is self explanatory, I see two options for “lightstrip” in the yeelight app, I may have accidentally set up my lightstrip 1S as a regular lightstrip.
I’m concerned that there may be some features I’m missing due to not setting it up as the correct product, even more so because I updated the firmware while my lightstrip 1S was set up as a regular lightstrip.
As far as I can see all advertised features work but it’s better to ask what is the difference with the two? I couldn’t find it on google.
