Core aesthetics are nothing but marketing, if they just left the cores looking "normal," you'd have a bunch of bland looking geometry shapes that are just manipulated to get the numbers they're after. So it's a lightbulb, don't care, the numbers are what matter. The reaction is what makes it an HP3 line ball, not the way the core looks. Very strong numbers for a lightbulb core, if you want to pay attention to what actually matters.
