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?

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.

For those comparing the Nukit Torches to the Aerolamp, please understand that they are designed for very different uses: the Torch is portable, battery operated and made to be safe for skin and eye at close range and for extended duration, where as the Aerolamp is clearly for (semi-) permanent use in larger areas and NOT up close to people’s faces.

These differences matter!

Also, for larger areas, there is another light from Nukit, the Lantern, with comparible output to the Aerolamp.

Lamp-Life : this is an unclear metric at this moment. Nukit estimates 2-4k hours and is cautious to not overstate the lifespan. For the other manufacturers I cannot be sure. Fact is that lamp manufacturers use a number where an x% of lamps can fail before they determine the life time. So if that x% is 50% , 500 of a total of 1000 lamps can fail during 14.000 lamp hours and the lifetime will still be rated as “14.000 hours”….. meanwhile, some lamps will fail after 500-1000-2000-4000 etc hours…
