Wanted: An LED Lamp That Could Outlast You

By tapping microprocessor cooling technology, industrial designer Jack Dyson develops an LED lamp that can last 12 hours a day, for 37 years.

LEDs are the best lightbulbs to meet the demands of an environmentally enlightened future, but they’ve got a dirty little secret: They aren’t always as efficient as advertised. One of the biggest problems is that they overheat, which chisels away at the bulbs’ life span. According to data from the Lighting Research Center, an LED at 45 degrees Celsius might last for about 100,000 hours, whereas an LED at 85 degrees Celsius might deteriorate in as few as 10,000 hours.

British industrial design studio Jake Dyson Products believes it has invented a way to extend LEDs’ longevity by tapping technology originally developed for satellites (now commonly used to cool microprocessors). Shaped like a construction crane, the CSYS LED task light has a pipe in the horizontal arm that conducts warmth away from the LEDs (at the arm’s tip) and discharges heat evenly over the rest of the arm. That keeps the light source cool enough to last 160,000 hours, or 12 hours a day for about 37 years, according to the studio’s calculations. As they tell it: "The chances are the LEDs will last longer than you do!"

The CSYS LED task light debuted at Designjunction during the London Design Festival late last month. It’ll be available in the United States in May for approximately $925.

    Was going to say, you nab this from Wired? haha... Its been up on his site for a while now, very cool lamp... I've never been a fan of the 'clamp' look, but this is executed very well.

    This is the dilemma faced by all of these bulbs. How do you justify paying 1000 times the price of an incandescent for a bulb that MAY last 54 years (but probably won't, at 8 hrs a day) I realize you are getting an "artsy" fixture, but please, you could change a bulb once a month for 54 years and still have money left over to buy a similar incandescent fixture. Phillips sells LED flood-lamps for $39 and advertise a 10,000 hour lifespan,  a little under 3.5 years at 8 hrs a day. You could change an incandescent flood every 4 months, and have cash leftover.  I love LED lamps, I have four in display cabinets that burn 24 hours a day and range in age from 6 mos to 30 mos old, I haven't had to replace one yet. And I realize there can be a tremendous difference in power consumption between a 60 watt incandescent and a 2 watt LED, but the cost of lighting is obscured by the $400 a month air conditioning costs in Texas. So until the price comes down, instead of the super-lamp in this article, I'll probably pay a couple on months' electric bills, buy a couple of replacement incandescent bulbs, and have a nice dinner out with the remainder.

    I love Dyson's work, and the heat and longevity issues of LEDs are very real. The design of the lamp is very similar to Pablo Pardo's Brazo lamp though.
