Thank you for confirming that I am still able to read datasheets correctly.Yeah, they actually do. The sheet is a bit confusing because the columns are arranged different than most. You are probably used to seeing the "min flux / typical flux / max flux" column layout and looked at the middle column for the numbers to use - that was apparent from the ~7000 lumen figure you jumped on initially. But Luminus lists the typical figures in the FIRST column - which is 8285L just as Random indicated - and that is the 85C number.
The Luminus datasheets are a little different, but every manufacturer cooks his own soup in this area.
I find them actually quite easy to read, even if they do not contain as many calculations as, for example, the Bridgelux data sheets. The latter contain much more info, but this can sometimes be more confusing.
Earlier, we had a thread with the latest data sheets of the most manufacturers, but it is unfortunately no longer maintained, since more and more manufacturers entered the scene.
