I don't know the GP's reason, but I also orderd long aluminum profiles for LED installations (it's needed for heat dissipation, and also helped with mounting in my case).

I ordered a bunch of 8ft lengths of aluminum 80/20 extrusion for framing the inside of a camper a year or two ago.

8' is a standard length for metal bar. OP might just have been buying their normal increment.
