yeah, the round ones let the electrons flow better:whistling2:just like round ductsAn oval shape dissipates internally generated heat better, assuming the same enclosed volume, because an oval has more surface area than a circle.
Maybe this shape change was for that purpose, maybe not.
Check it before installing, at least for a short.
Wrong. that is just perspective that makes it appear oval.Yes, but those electrons travel in an oval orbit............... OVAL!! :thumbup:
