Light upgrade?

They list the efficiency higher up on the page at 2.75 on the G3000. I see what you mean about the lumens though. How can SF claim the G series is more efficient when the lumens per watt are clearly less? I definitely like the idea of better efficiency, I just thought 500 PPF was kinda the min and the SF didn’t seem to hit that on the edges.
