>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.
Sure, I'm game! I can loop you into our comms with LLA and you can do the same, and they can send us both the results as they come in. OSLUV says they're happy to pay for it too so no worries about the expense
I really do think the ushio bulb will last 13.5k+ hours though, and that's a long time to wait--how about we publish the LLA results at 1000 hours, and every subsequent 1000 hour interval after that? At minimum, it should give us a sense for how the lamps are performing, even though we might not get the L70 lifetime for a while. Then, as soon as LLA has confirmed receipt of both our samples we can both retract our lifetime claims, at least until the first 1000 hour interval
Just let me know a good email for you and we can get the ball rolling on this, you can get me at vivian@aerolamp.net
