Really? So be so kind to name the canon source that says those light panels on the Refit bridge rim and lower sensor dome are "scanners" (remember, canon in Star Trek is only what was seen and said in the movies / TV series).
Well, if you want to go with that definition... be so kind as to name the "canon" source in the movies which makes it clear that the bridge is in that dome, or that the things above and behind the ship are the warp engines, or that the thing at the front of the secondary hull is a sensor/deflector device.
I, personally, will accept the "off-screen" information given by Lee Cole, David Kimble, and Andrew Probert, even if you don't.
And since none of this "really" exists... I guess neither one can be defined as 100% correct, huh?
AFIK those light panels have always been identified as the sources of the Refit spotlights with the prominent source beeing TMP when the spot lights come on at the dry dock "power up" sequence.
That two things happen at one time does not make them the same thing.
When you put the key into the ignition of your car, and turn it, a number of things happen all at once. Does that mean that they're all the same thing?
Yes, we see individual systems turning on all across the ship's exterior, in a sequence... but is that intended to show us things happening in that sequence, or perhaps might that not be a series of events which "really" happened all at once, but could not effectively be shown to us "all at once?"
I see no conclusive indication that the HUGE SLOTS exist for the sole purpose of being really large, awkward, inefficient light sources. Especially given that, even today, our technology is far, far more advanced than that.
I said, earlier, that it's POSSIBLE (though it would seem like poor design practice) that the lamps might be installed among the scanner equipment in those arrays. You ignore that, of course, and insist that the slots must be ONLY LIGHT SOURCES.
In other words, you're taking a very aggressive tone... saying that you, and only you, must be 100% right. I'm sorry, but that's just unjustifiable.
The bridge light coming on with no spot at the top registry in ST3 was to say "Kirk and Crew have arrived at the ships bridge" after the Mr Adventure scene.
But, by your own claim, "if it's seen on-screen, it's canon." So... by your own argument, this is NOT the source of the "banner lighting." You can't use an argument at one moment, then abandon it at the next, out of pure convenience.
Happened in TMP too. Just after the wormhole incident and after Spock arrived the ship passes by at presumably impulse, Kirk makes a log report and states the warp engines are being repaired, yet the nacelles inner warp grills are glowing blue and the dish is blue as well. But to give the makers credit: they just reused this shot that was obviously as a "warp flyby" for use after the frist successful warp flight. It's the same shot, you can tell by the flicker of the port pylons flood light. Look out for it in both sequences and you'll see.
I'm not convinced that this is the same shot. While it's similar, to be sure, I don't see the identicalness you do, and I believe I see some differences.
Still, it hardly matters.
Look... you can believe whatever you want to believe, and since there is no "real" Enterprise, you can treat those roughly fifteen foot by three foot openings as being very, very crude illumination sources, rather than as anything else.
What we DO know is this:
1) In the model, they did not actually produce a "flood light effect." The effects seen were produced by external light sources.
2) As seen on-screen, these can be illuminated without the "banner lighting" being present.
3) The "banner illumination" is AHEAD. There is not an identical patch offset at the +/- 75-degree locations aligned with the other two slots.
4) Those who designed and defined the ship, for TMP, called those slots sensor/scanner ports (even if this was never stated in on-screen dialog).
So... I have never accepted those as the source of the illumination.
Your mileage may vary. And that's OK, because it's a MAKE BELIEVE SHIP, after all.:wave:
