It's canon!![]()
The only 'canon' I often care about is the one I get to shoot some fanbois out of.

I've always been a 'use what works' guy, so I guess I'm a lot more like Franz Joseph in that regard that a 'canonista' that demands everything on screen MUST be real (even when it's stupid or nonsensical).
I always found the bulbs lacking, really. On my badly-built model Enterprise, for instance, it's the 'production' build with the 'advanced grill' on back. Just looks a LOT better to me. But then, I also liked the black markings on the primary hull, too...
