If the ceiling is opened up, why not install traditional can lighting with led bulbs or led trims? I’ve used a product similar to what you linked to and I wasn’t impressed with them. Ended up replacing with cut in cans and led trims.
Did some more cleaning.... I have a work table that came with the house that had a radial arm saw built into it. I took the table apart today and removed the saw, I’ll be giving it away ... table back in place and way more usable now!
I didn’t notice any cracks... there were some spots while cleaning that created a spider web like look in the rust/dirt, but I never saw any cracks....
