Manufacturers like to list this spec to consumers because it sounds amazing and relatively easy to measure but it really says nothingabout how long your panel will last. That comes down to Production Line Quality and how well the Design Team did in designing sub-compoents with enough margin in them to account for shifts in the distributions and grade of the lower level components.
Nope, it all comes down to how much supply chain changed the specs to save a nickle. I'm the design engineer that gets a bad rap because of supply chain!!!
