So, when the lights dim, it is due to more current (amperes) being called for than is being delivered.

Don't start with the Engineer stuff. I work with them all the time. I am a certified Industrial Electrician.
Pissing contests achieve nothing.

The only way current will flow out of the alternator is if its output voltage is higher than the battery voltage.
So the term watts is not incorrect
