40" Light Bar for Prinsu Rack

Before I purchase a Prinsu rack, I am wondering if there is any light bars that you can buy that ARE NOT $300-$1600. I've found some light bars that are "40in" but you look at the specs and its 41" or 42" overall length. Would those fit or does the overall length need to be 40". Thanks

 

When I first got my Prinsu I ran a bar I got from Aliexpress. It was decent but after a few months filled with water. Somehow I was able to get a replacement (which was lucky). So on that one I took the lenses off and filled it with silicone. I ran that for years without issue. Then I got a Rigid Radiance from Facebook Marketplace used and I've been running it ever since. They advertise the "light area" as 40 inches and the frame brings it out to 41-42. No biggie.
