Not sure about the point of this. Okay, the heat pipe is a reasonable idea, but a light that matches my local sun cycle would be useless: At night (when I actually need it) it would be off. Clearly I'm missing something.

Even that is not.

...water cooling process works by condensation. As the processor heats up, the liquid essentially vaporizes, keeping the CPU cool. The vapor then travels to the opposite end of the of the heat pipe, where it condenses back into liquid when cooled off.

This is crazy expensive for a desk lamp, but I can imagine applications that would justify expensive lighting. I’d happily pay 10-20x premium for guaranteed ultra-long life bulbs to use in built-in home fixtures—especially difficult-to-reach locations.

The daylight cycle matching (and the manual tuning) varies color temp between 2700K and 6500K; it doesn't (at least, in any of the description) vary light level. It's basically the same concept (but more localized) as f.lux for desktop screens.

This has some very appealing aspects—I'm particularly intrigued by the stand design—but I'm mystified by the idea that a lamp designed to last six decades apparently requires an app to operate many of it's key features. Sixty years ago there was, as far as I can tell, one significant digital network in the world[0], and the smallest computers weren't desktops--they were desks.[1] It seems all but impossible that Dyson's app is still going to be available and functional for more than maybe a decade of this lamp's projected lifespan. Computer technology just evolves too fast. I would really appreciate if $600+ appliances would include in the box everything that they need to operate to the best of their capabilities, so that we don't end up with lamps stuck in alarm clock mode when Dyson doesn't upgrade their app to work with iOS 16.

That's great, but who wants to pay that much to have the same light for 60 years? One "advantage" of consumerism is cheap = changeable The sad part of modern technology is that you can't fix it yourself, nor do you understand how it works. It doesn't make you any smarter. That said, having a luxury product that last 60 years is a very niche market.

> 60 years

Yet they only provide a 5 year warranty. I would expect a $600 desk lamp to have at a lifetime warranty.

And they couldn’t even be bothered to get the warranty details right: at the top of the page, it says parts and labor, but at the bottom it says parts only.

I have a Shuttle PC from 2003 with heat pipe cooling. For about 10 years, they made machines with a heat pipe system to transfer heat from the CPU chip surface to a finned plate at the back of the box behind the fan, allowing a more compact package.

But for an LED? Come on.

The cutting edge technology in LED lighting is to use power supplies that don't need electrolytic capacitors. The capacitor usually fails long before the LED.
