>Here is a paper showing that the USHIO care222 module achieves an L70 of at least 10,000 hours: https://www.jstage.jst.go.jp/article/lsj/50/7/50_394/_pdf

The scientists who wrote this paper work directly for Ushio, correct? And it has not been replicated or verified in any way?

>I am simply explaining why I decline to believe this 3000-5000 hour claim that is presently without any substantiation whatsoever

Very sensible, it should be checked also and claims until then retracted.

>This is why Aerolamp has submitted multiple samples to LightLab Allentown for lifetime testing. Perhaps you would be willing to do the same, given how frequently you emphasize the importance of third-party data?

Sounds like a great idea, we have multiple new gas formulations to test and low-cost replaceable bulbs mean it will be easy to offer customers greater operating life as we improve them. Perhaps Aerolamp would also like to refrain from making any claims without third party data as well? It would be a good example for us to set.
