- sp332 11y agoI thought heat pipes needed convection to work. How would the liquid move in a straight, level pipe?
- t3f 11y agoThere are a number of different ways to build heat pipes. A few of the common designs typically used in cpu heatsinks and laptops do not rely on gravity or centrifugal force. Based on the skimpy page content, it appears they are using the more common wick/capillary system here. I'm not seeing anything ground breaking in their blurb, but maybe they left out the fancy part.
- daughart 11y agoI think it's just a metal heat sink, no liquid?

- putterson 11y agoThe liquid in a heat pipe can return to the hot end through capillary action, and I believe this is how heat pipes in computer equipment work. They can work in any orientation. https://en.wikipedia.org/wiki/Heat_pipe https://en.wikipedia.org/wiki/Heat_pipe
- bri3d 11y agoI agree that this is most likely to be a capillary-pumped heat pipe.

- jloughry 11y agoThe return mechanism is via capillary action; surprisingly, heat pipes work in any orientation, even freefall. Very high g-forces can prevent them working, though.
- jschulenklopper 11y agoThere's no liquid involved. They use a copper part, similar to the heat sinks on CPUs.
- sp332 11y agoYou are wrong. Look at all the other responses. And https://en.wikipedia.org/wiki/Heat_pipe https://en.wikipedia.org/wiki/Heat_pipe
- MeNotMe 11y agoI 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.
- devy 11y agoOf all the dyson products I have (2 vacs, 1 bladeless fan), customer service is the weakest link. The fan has a recall last year, they should have emailed customers shipping labels to print out to drop off the product at our convenience, but rather ask you to visit a local UPS B&M store and the store clerk had to fax the RMA request in. The whole thing took 2 hours on a busy Saturday. Completely failed customer service for a premium product that sells at 5x-10x the price of others. Yes the build quality is good, but not that good to worth 5x-10x the average price for the same product. And certainly not worth the hassles to deal with their customer support.
- leonroy 11y agoIn the UK at least Customer Service is superb. I honestly cannot rate the company enough. On the few occasions I've needed anything Dyson simply ask for the serial number and I describe the part. Next day or two and it arrives in the post. They also do on site visits if the vacuum has any issues. £80 labour and parts inclusive. I mean my mum still uses her DC02 from 1995 and it works just fine. They're (in the UK at least) a top, top company.
- dceddia 11y agoI've got a Dyson DC18 and it's been good as far as I can tell, but I haven't compared it with anything else. What did you replace it with? Is the replacement better? Did you try any side-by-side comparisons?
- MeNotMe 11y ago1. I've replaced it with a Miele and a Siemens (needed two) 2. The both clean better, I find less dirt in carpets and e.g. in corners than with the Dyson. 3. Personal subjective opinion: Having a bag is cleaner for me.
- giarc 11y agoStays bright for 37 years, has a 2 year warranty.
- rcaught 11y agoI think a true innovation would be a light that stayed bright for 2 years and had a 37 year warranty.
- Gonzih 11y agoIsn't it a bit too much for an LED light?
- ohitsdom 11y agoIs 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.
- knodi123 11y ago> Is this a joke? I see you're new to Dyson's business model. Keep in mind, these are the guys who make a $400 fan in a niche full of $10 competitors.
- Someone1234 11y agoAnd ignoring how it looks for a second, the Dyson Air Multiplier is kind of mediocre anyway (and VERY mediocre for the price point). The rest of the electric fan market has shifted over the last ten-ish years to noise-efficiency. Meaning the most air movement for the least amount of noise. So we've seen new blade shapes, smarter motor designs, enclosures that attempt to dampen the noise, and so on. And Dyson's Air Multiplier could, in theory, have done well in that competition but they care more about form than function, so they stuck this tiny little motor with a higher RPM in the thing which has made it extremely loud for the amount of air that it can move. In terms of noise-efficiency, it sounds as loud as fans from the 1990s and before.
- zimpenfish 11y agoApropos of nothing, Muji's USB desktop fan has contra-rotating blades and is amazingly quiet for the amount of air it can shift.
- freehunter 11y agoYeah, 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.

- noipv4 11y agoHeat 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?
- theandrewbailey 11y agoProbably. 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?
- noir_lord 11y agosufficiently 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.
- Cshelton 11y agoAt what point does a product last "too long"? It seems that designing an expensive lamp and marketing the fact that it lasts 37 years seems kinda...dumb. First there is the issue at the business level. Returning customers are the easiest and cheapest sells...but if your customer only buys a product every 30+ years...not great for business. Then there is the technology. Why make something last that long with current technology when in 10 years or less, something more efficient and "better" will come along. I'm not sure many people can even keep track of a lamp over that long. Between moving, things breaking, etc.
- apalmer 11y agoWell, one point is purely as a marketing tool. I doubt very few of these lamps will ever last 30+ years, due to moving, accidents etc, and probably dyson doesnt either. however its effective to say that in marketing. Outside of that, people expect certain pieces of hardware to just 'work' forever. Generally they don't expect a lamp to ever 'require' an upgrade. Yes it will probably be replaced for some reason in that timespan, but not generally due to 'failure'
- kardos 11y ago>First there is the issue at the business level. Returning customers are the easiest and cheapest sells...but if your customer only buys a product every 30+ years...not great for business. This exact line of thinking has created scads of products that suffer from the opposite problem -- products that are kind of cheap and need to be repurchased every couple years, overall costing several times more than a good product would and generating several times more garbage. > At what point does a product last "too long"? It seems that designing an expensive lamp and marketing the fact that it lasts 37 years seems kinda...dumb. Well it is somewhat dumb because nobody believes it will last 37 years, partly because of the "everything is junk these days" effect that we've come to expect, but also because it comes with a two year warranty.
- makomk 11y agoThe LEDs last 37 years (well, 154,000 hours). I have a feeling that, for example, the capacitors in the power supply won't last that long. I also notice that they only provide a 2 year limited warranty. (LED lamp lifespan tends to be limited by other components failing in general, unless you get dodgy LEDs or do something really screwy with the cooling.)
- thrownaway2424 11y agoIt looks perfect for a cleanroom but in my office those little wheels would be covered in dust immediately.
- Eric_WVGG 11y agoThere’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 http://www.dyson.com/lighting/ariel.aspx

- cptchaos 11y agoThey don't even tell you how bright their expensive lights are. they give some value in lux but that depends on the distance in which it is measured. I want lumen values!
- mattkevan 11y agoHave you seen their other lighting product? That's some serious heat-sinking! http://www.dyson.com/lighting/ariel.aspx http://www.dyson.com/lighting/ariel.aspx
- boyanpro 11y agoYeah, right. Like a normal person will pay that much for a lamp.
- Eric_WVGG 11y agoWhat suggested to you that the target audience was “normal persons”?
- makomk 11y agoIs it just me, or does this completely fail to mention the amount of lumens it produces, the wattage of the lamp, or the incandescent-equivalent rating? Basically, all the fundamental parameters you'd normally expect when buying a lamp aren't there.
- zimpenfish 11y ago"Eight LEDs provide 587lx of warm, white light for 37 years" But that's the only reference on the page.
- makomk 11y agoYeah, which is pretty meaningless because lux is a measure of light intensity at one particular spot and it doesn't provide any information about the distance at which that's measured, how big an area it'll reach that lux value over, or anything. My little 1 watt torch could probably produce ridiculous amounts of lux so long as it was only over an area the size of a postage stamp, for example.
- pgib 11y agoI'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.
- blacksmith_tb 11y agoLED bulbs have been getting gradually closer to the color fidelity of incandescents, I would think for most people in most situations, those with a CRI greater than 90 would be sufficient (certainly worth it for the the efficiency gain), e.g. https://en.wikipedia.org/wiki/High_CRI_LED_lighting https://en.wikipedia.org/wiki/High_CRI_LED_lighting
- chrisbennet 11y agoI have a Koncept Z-bar desk lamp (~$300) that I got at my lighting shop after looking for something that was cool to the touch and had a nice even light pattern. One minute I use it on "low" for lighting up my desk and the next I'm using it at full brightness for computer vision tasks. I suspect that you have to be old enough that your eyes need a little help before you can appreciate a good lamp.
