I have downloaded and looked at the tests from Aerolamp and Nukit Torch.
Aerolamp does show a consistent output and seems to be a well thought out design for its use: larger rooms, giving overhead exposure, not close to people so mainly ceiling mounted.
The Nukit Torch was modified for continuous use, while it is not designed for that. I am not sure that leads to completely objective test results.
My question is: What is the basis for your assessment that the expected lifetime of your product is 10 to 14 times longer?
Moreover, with all the electronic components that are nowadays incorporated in modern lighting equipment it is not only the “bulb” that can fail. Many “20.000 to 50.000 hours”-LED products from reputable manufacturers have shown to fail after only a few 1000 hours or less. And often the LED’s themselves are OK but the power supply or ballast failed somewhere.
So I am wary of these claims without knowing the testing method.
This paper shows up to 10k hours for the Ushio B1 bulb: https://www.jstage.jst.go.jp/article/lsj/50/7/50_394/_pdf this poster extends the data and shows an L70 of around ~13.5k hours: https://cdn.shopify.com/s/files/1/0694/8637/9189/files/240617_Yagyu_ICFUST_Poster2V2.pptx?v=1751931924 I’ve also seen a fair amount of testing from OSLUV that makes me personally believe these publications—Ushio sank 10 years of R&D into their emitter, and it’s really good. It’s also expensive, limited in some ways, and only available from one manufacturer, but it definitely seems to have great stable output and impressive lifespan. But fair point about the electronics—the lifetime estimate is based on the bulb lifetime. Aerolamp hasn’t even existed for 10,000 hours. This is why we have a no-questions-asked return/replace policy—if your lamp fails we’ll send you a new one.
Thank you for the links, very helpful. Also interesting to see that the lamp consists of 4 separate bulbs. I suppose that will help with the longevity as every bulb makes a 1⁄4 of the output, where as other designs might to lead to “overdrive”, improving temporary maximum output but at a cost of earlier degradation.
When do you think the Aerolamp will be available outside the USA?
Yeah I think that is part of it! Excimer lamps are really cool. They do all sorts of other stuff too, monkeying with the glass composition, gas mix, voltage waveform, etc. It’s pretty optimized—I’m hopeful that other bulb manufacturers will copy them(/have the market incentive to bother copying them), a lot of these optimizations are totally public information that’s been published in journals since the 90s.
I’m hopeful that we can start a slow rollout of international shipping in the next few days/weeks, we’re setting things up with DHL right now
