I have a 3' LED one in my loft. If i wanted to add another i can wire it into the other end of the first one. I am sure there must be a limit to how many i can link but handy none the less.
I’ve got 3 x 5 foot LED battens in my 24 x 24 foot garage plus two led bathroom bulkhead light switched by PIR. The battens are more than enough for the space.
If I had a dedicated / fixed workbench the I’d likely add another over that on a separate switch to ensure that area was well lit but the bench is on castors as it serves as an outfeed table for the table saw / assembly bench as such it moved to where it is needed.
