Heat pipes are used in laptop, desktop, GPU heatsinks and coolers. They are also commonly used in oil-pipes thru permafrost. Are they using some interesting long-life LEDs?

Probably. The heatpipes are either overkill, or these LEDs run very hot (combined 10W+ of heat). Wouldn't the metal frame of the lamp itself sufficiently cool 'normal' LEDs?

sufficiently cool may not be enough to get the stated life.

Like a processor running at 70C vs 35C, 70C is sufficiently cool (it's within spec say at 80C) but heat damage is continuous.

Is this a joke? $600+ for a desk LED lamp? Even if current LEDs lose brightness, you could just replace the bulb every month for the next 10 years before this lamp even came close to an ROI. But I guess Dyson isn't going after the "value" market, just the cool factor.

Well, the tall one will go well with an Eames chair [0]. Point being there is a niche market for practical lifestyle product which may go against conventional wisdom. [0] http://www.hermanmiller.com/products/seating/lounge-seating/...

Or, if you want to match the harsh geometry of the lamp, a Rietvald Zig-Zag chair:

Is there a good website that rates fans by power/noise/price? I don't actually care about the price much, I really want a quieter fan that won't make me turn up the music too loud to hear the details and wake anyone up.

My mom once got a Dyson vacuum cleaner. I can only assume Dyson pivoted from making a jet engine.

It's the only one where vacuuming becomes kind of fun because it actually works

I was such a huge Dyson fan, bought a cleaner a decade ago, read his books. Had the suspicion the cleaner was crap. Lots of reviews said the same. But I convinced myself I and the others were wrong, Dyson is a genius. Some years ago I finally admitted it was expensive crap and got something else.

Huh. I have a Dyson vacuum; it works really well vs the other vacuums I've had. Might be a case of "have not bought decent vacuums before", but it does work.

I'm really surprised that there are no technical specifications that would include, say, colour temperature. I've yet to see an LED bulb that produces light anywhere close to the warmth and spectrum spread as a halogen bulb. At $649, I'd definitely need to see that in person.

I'd also be in favour of a 37 year payment plan at $17.54/year.

It looks perfect for a cleanroom but in my office those little wheels would be covered in dust immediately.

There’s also an “Ariel” lamp that doesn’t appear to have any moving parts, but I imagine those fins would be a disaster… http://www.dyson.com/lighting/ariel.aspx

Yeah, it's getting hard to find a fan that I can run at night to cover the noise of the city. Every time I buy a fan, it's quieter and quieter, but I like loud fans to help me sleep.

No sarcasm: Look into Nursery Sleep Soothers. While they sell white noise machines targeted at adults, they're all terrible because it is a niche market. But in the nursery sleep soothers category you can find a bunch of high quality white noise machines for a good price.

For example the Marpac Dohm has an actual spinning fan inside designed to generate white noise. But you can find digital noise simulators who can do: industrial sounds, water, fan noise, nature, and so on.

I am the OP. Yes, that's the same reaction I had when I first noticed it. The funny thing is, they aren't even backing their "premium LED lighting" product the same way they did for vacs, which has 5-year limited warrant. LED lighting gets only Free 2 year limited warranty, even though they claimed "37 years" of lift span based on some calculation. One might wonder, will they still be around in business after 37 year…

The LEDs may well last that long. The electronics providing the correct voltage/current to the LEDs, not so much.

On the LEDs, the industry accepted method for measuring lumen maintenance of LEDs sets an "upper reporting bound" on LED life estimates at 6x the length of test data, since we aren't sure whether the prediction model will hold true over the longer term. Either you report L70 as the time when output drops below 70% of original, or you report it like "L70 > 60,000 hours" (if you had 10,000 hours of testing and it was predicted to stay above 70% at 60,000 hours).

Dyson is claiming 154000 hours, implying that they have over 25000 hours of test data. This is very light on supporting data, so I'm naturally skeptical of it. It's not uncommon to see people ignoring the 6x upper reporting bound because they want to publish a big number that may or may not actually mean anything. Dyson also don't mention whether they're talking about L70, L90, or some other criteria. L70 is typical, so I assume it's that.

I'd expect to see a INTMT test and their LM-79 lumen maintenance calculation, based on the temperature data and calculated in EnergyStar's freely available LM-79 spreadsheet. For high-end lighting products, this information gets published.
