My employer purchased 277v LED light bars to install as replacements for emergency lighting. I am unable to find UL or any other marking on the fixtures. Can I install these fixtures or does 110.3 b or any other codes prevent using a non listed fixture? I am in the process of requesting testing info. from the vendor. What testing agencies are acceptable?

The AHJ would be the final arbitrator and they generally require some recognized listing. Since this is emergency lighting, it is even more dicey as they would require special listing for the purpose.

Wasn't I correct stating that the AHJ can wave that requirement? (Not that they should or would.)

Since listing is now a specific requirement, I believe a waiver under Section 90.4, Paragraph 2 is extremely unlikely without a solid substantiation (need) since it's no longer just a "judgement call.". Many jurisdictions have had a general third-party listing requirement long before the NEC made it "official" for luminaires. So could? Of course; but don't count on it since there's virtually no demonstrable need to and takes too much paper work. Should? - well, that's a different debate.

90.4 Enforcement.
...
By special permisson, the authority having jurisdiction may waive specific requirements in this Code or permit alternative methods where it is assured that equivalent objectives can be achieved by establishing and maintaining effective safety.

Just as a side note ....

I do not think this specific code requirement will result in the slightest improvement in safety. I only regret that I did not know of the proposal and missed the chance to make this comment when it might have done some good.

My reasoning is quite simple: prior to this requirement, every fixture maker made a significant part of their production without the labels. This made the specific fixtures 'unlisted.' The fixtures were otherwise identical in every way to the listed product.

Why did they do this? Money, plain and simple. There was a significant cost for each label. Manufacturers often offered the exact same fixture at two prices - labelled and not. The customer was able to decide for themselves whether the maunfacturer was competent.

Had I but known this was coming, I would have bought stock in UL ... wait a moment, you can't do that, as it's "privately held." Oops. Well, guess who just saw a revenue increase?
