This is the most insane LAMP that last 40 years ( Huge Heatsink)

[samuel]

I have a 2x 4x100W LEDs lighthouse on my crane at work and it's working 24/7 for 3-4 years now. The price should be under $100...or alot less when the company buys like 500 of these for industrial use.

And presumably you can also tune the colour of the light emitted by the LED? The light-bulb in my bedroom is a "daylight" lightbulb and I feel like I get less headaches with it compared to with a conventional energy-saving flourescent or one of the old-fashioned incandescent bulbs.

[Mush Brain]

I will just OC my energy saving bulbs....

[Scheer]

This solves the primary issue with the marketing behind LED bulbs, the LED itself will last for a very long time, its the converter that goes out on them...

 

 

Someone crunch the numbers on electricity cost vs this thing over 50 40 years.

edit: a number

 

Its a 101W bulb, figure it uses 125W (.125 kw) after the AC/DC converter for easy math... National average cost of electricity is 12.2 cents.

 

350400 hours in 40 years, so 43,800kwh in total, times the cost of electricity per kwh for a total of $4,489.5 not including inflation.

 

By comparison, using normal lights for the same coverage would likely cost you 5 times that amount in electricity, and you also have the added cost and hassle of replacing bulbs.

 

I've installed a two dozen or so LED bulbs in my house and have been very happy with them so far, and have noticed a small drop in my electricity bill with those alone. Mainly because in my workshop (on for 6 hours a day) I replaced 14 100W bulbs with 20W LED equivalents and saves me about 60 cents a day, $18 a month. So the bulbs will pay for themselves in about a year... as long as none go out.

 

PS. If you ever think your mom is dumb for complaining that you leave the lights on, the cost really does add up quite fast and you should listen to her.

A light bulb working since 1901. Whaddya think?

[steffen_anywhere]

, what is the wattage on that lamp? An 8W led lamp is already pretty bright, if it needs that large of a passive heatsink to stay under 55°C it must be like a small sun.

 

101W...Pretty beefy for an LED array

I don't mind 3D renders to show a product, but using them to show how it performs makes me laugh.

It looks like that poorly tracked Cicre bracelet android thingie.

[JAKEBAB]

It looks really cool but i dont know how practical it is for your regular consumer. (thats if it is even aimed at regular consumers.)

[ionbasa]

Lol. Saw "LAMP" in the title and thought of Linux, Apache, MySQL, PHP server that could last 40 years.

[jfing14]

I think more people would buy this lamp just for its sick as F**K looks than the fact that it will last 40 years. Regardless they better crank up the warranty in this b***h cause I aint dropping 2K anytime soon on a lamp if it gonna blow on me in a couple of years

[McMurderMonkey]

That looks pretty damn cool, but when I saw it on the WAN Show Archive, I didn't realise that it was like 70-freaking-percent heatsink!

[APrettyCoolWalrus]

how is that possible there are only 12 hours in a day

Please tell me that you mean there are 12 hours of daylight

To be honest, when I saw this post I though he was talking about this lamp... It survied so much stuff, earthquakes, fires, (maybe the Nazi's?)

[Noctus]

*ahem* http://en.wikipedia.org/wiki/Longest-lasting_light_bulbs

 

"The world's longest lasting light bulb is the Centennial Light located at 4550 East Avenue, Livermore, California. It is maintained by the Livermore-Pleasanton Fire Department. The fire department claims that the bulb is at least 110 years old (installed 1901) and has only been turned off a handful of times."

 

"...While it might seem astonishing that so many longest-lasting light bulbs have been so infrequently turned off, this is the precise reason for their longevity. Most of the wear and tear that leads to burnouts in incandescent light bulbs is caused by turning them on and off, not by burning them. Each time the bulb is turned on and off, the filament is heated and cooled. This causes the material of the filament to expand and contract, in turn causing tiny stress cracks to develop. The more the light is turned on and off, the larger these cracks grow, until eventually the filament breaks at some point, causing the light to burn out."

A bulb that happens to have lasted a while where other have failed vs one that can be mass produced and cut cost's compared to today's lighting systems.

[pit5000]

regular LED cost about $10 or so, lasts 10-20 years

Oh come on... why so serious? I pulled the most extreme example in the book.

And if you want to seriously compete with incandescents, LEDs are not quite there, and neither are halogens. It will take a different technology to do that. 

The LED spectrum is too narrow and therefore unnatural. Halogens do more damage to the power distribution network than they save power in great quantities.

oops wrong planet

[kameshss]

Me gonna put Noctua NF-P12 fans on it! lolz!

But Edison was a thief LOL.

[Thony]

How do u test a freaking light bulb if ut lasts fir 40 years ???

Also for that price he can gtfo.

[Aniallation]

Somebody needs to strap some fans to that heatsink then attach it to a 290X. That'll finally keep those things cool
