Light duty doesn’t sound like the tile is rated for flooring use - sounds like decorative trim tile only. And would glass tile be slippery? Definitely not good for flooring in a room with running water & wet feet.

Only vitrified glass is floor rated, and it's not the pretty sparkly slippery kind of glass.

We have 1”square glass tiles on a bathroom floor and it’s lovely. The size makes it non slip. It’s a half bath essentially and has been installed for four years

A bathroom qualifies as having a "light duty floor" unless you're bring in furniture or moving the toilet often. Go for it, but be sure your installers know how to install it without mortar lines showing through.

Use it on your walls. Not the floor

No way should that be used on a floor, glass isn't designed for that, as others have said .. walls only, regardless of what the packaging says.
