It's novel for an LED lamp, though. Most manufacturers just put a heatsink on the back. It's ugly. If you're going for the best possible LED lamp, irrespective of cost, I can't think of a better cooling method.

Kinda? It already exists, but usually to better spread heat to the sink in high-power LED lamps (50W+, not equivalent, actual).

And my point is outlining that it's "satellite technology" is complete bullshit marketing copy.

I would expect more or less every laptop with fans[0] to use heatpipes, even for gaming / workstation laptops it hasn't made sense to stick a radiator on the CPU/GPU in a long time.

[0] apparently fanless devices don't, I guess there wouldn't be enough of a heat differential between the CPU and a hypothetical heatspreader for it to work?

Can't edit anymore, but just thought a bit more about it: more or less every laptop with a fan would also be using heatpipes, especially with the "quest for thin-ness" few modern laptops can afford to put a fan and a radiator on top of a CPU, so it's always heatpipes from the chips to a radiator in some sort of motherboard indent.

I understand the frustration but you really have the need for a bose soundsystem while not owning any modern computing device or smart phone?

Keep in mind that many (all?) smartphones are deliberately obsoleted within 2-3 years of release - as an example, my S5 (released 2014) only supports through Marshmallow (obsolete as of 2016). Any apps requiring Nougat or later are unavailable to me. Given that I personally use my phone for communication, browsing the web, reading, and note-taking (and occasionally SSH), this isn't a concern, but it might well be a d…

I reccomend installing lineageos. It works great on the s5 and still gets regular updates.

Its not too hard but you may want to dedicate an hour on the weekend to set it up.

Devices that require apps to use are infuriating. I recently got a bose soundbar and subwoofer and the instructions tell you to install the app so you can connect the subwoofer to the soundbar. I don't have any devices that can run the bose app... I eventually found out if you use an AUX cable (not included) you can connect the two devices together without an app.

I understand the frustration but you really have the need for a bose soundsystem while not owning any modern computing device or smart phone?

I run Linux on my computers and degoogled android on my phone. Do I not deserve to have speakers because I don't run google spyware? Why should speakers even need an app, I just want to plug them in and have sound.

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.

> but a light that matches my local sun cycle would be useless: At night (when I actually need it) it would be off. 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.

That might be OK for casual use but is a non-starter for anyone who deals with colours, photos or documents.

The entire 'warm white' concept is based around the colour temperature of candles, those being traditionally associated with night illumination. But look at the actual colour temp of an overcast sky just after Sunset; it's 5000K+ blue-grey, not 2500K yellow. The latter has no place in nature other than fire. Yet somehow our ancestors managed to go to sleep...

I think you just mean colors, but tried to find three different ways to say it (and kind of failed, because lots of people “deal with” document all the time and aren't concerned with color.)

At any rate, the light came be fixed at any supported point, too, the matching is just an available function, not something you are locked into. So for uses for which it doesn't meet your needs, you would just not use it.

> But look at the actual colour temp of an overcast sky

Not sure about handling the overcast part, but that's explicitly what this does otherwise.

> The latter has no place in nature other than fire. Yet somehow our ancestors managed to go to sleep...

Not sure what your point is, since the color of natural light just after sunset is only relevant here if you think humans are optimized for sleep at twilight. Which...they aren't.

Actually, I have a friend who works at a company which designs extreme heat pipes and heat wicks for satellite applications.

He has a satellite-spec heat pipe specimen which he shows around with heat-sensitive paint to demonstrate heat transfer speed, and it's way faster than conventional heat pipes. It's almost instant. Don't know the secret sauce though.

Personally, I'm done with Dyson. James was a vocal supporter of Brexit, gets what he wants, then decides to move his company's HQ to Singapore. That kind of blatant hypocrisy taints their products for me.

My coffee maker is from 1972 which makes it more than a decade older than the user. So there seems to be a market for high quality, unbreakable technology. But then again, how many years could it be operational when depending on an app.

Curious: What kind / brand is it?

An Olympia Cremina and Maximatic.

Whereas an Anglepoise lamp actually will last 60 years. Many already have. It's too early to know if their LED variant will. Dyson had one decent idea that everyone else adopted too - cyclones instead of bags. Everything else seems to require paying 10x what a sane premium and expensive cost might be - lamps, hair dryers, fan heaters. The innovation is making it appear complex enough to justify the absurd price. I be…

Disclosure: I design and sell lighting products.

The LED component probably will last 60 years (8 hours a day). My guess is they are using Nichia LEDs, which tend to have an L70 (lifetime at which the brightness stays above 70% of the original output) of 150,000 to 300,000 hours. If you run them cool enough and at the right current/voltage, the LED itself will actually last that long.

However, the LED is probably the most reliable part of the whole lamp. You might see a few units last that long, but most of the other electronics will have failed by then. And even if they have not failed, both the LEDs and controls will be seriously out of date by then.

If you look at the market Dyson is in (very high-end lighting), $600 to $900 is in the same order of magnitude on price. Brands like Artemide, Marset, Flos, Roll & Hill, and Anglepoise all command prices most people would think are ridiculous. With Dyson, you get a lot more functionality than those other brands, but I would consider this purchase more like a luxury car (service life of maybe 20 years, original owner has it for 3-10 years) than a high-end watch (could last many decades with consistent service).

I've seen the previous task lamp from Dyson in person, and it does use a lot of metal (minimal ABS). But that doesn't change the argument around electronics. I feel like Dyson really didn't have to make the ridiculous 60 year claim. Enough people in the target market would still buy it.
