    Looks like it's the same as the classic Luxeon star PCB.

    The assholes at Lumileds are too good to give out actual dimensions of the star PCB on their datasheets. Looking at some Cree stars I have from some other unknown Pacific Rim manufacturer, they have roughly the same footprint as some old Luxeon III stars I have.

    I'd be careful about running those things at more than ~350mA - Luxeon stars are well-engineered for heat transmission while almost all of the Cree stars aren't.
