I have a 2020 Cooper Metalux 4x F32T8 Commercial Grade wraparound and I was wondering if it's rare at all? Especially since it was made so recently.

It seems to be made kind of late for a 4x F32T8 fixture and it's surprisingly well made. I don't think they really ever changed the design since the ballast cover says rapid start lamps only. It's also identical to my 2013 one, except it came with a commercial grade ballast. And the box design is less fun, but that might just be since it's commercial grade.
