Skip to comments.Introducing the $60, 20-year light bulb ("Going Green" still "Going Ridiculous")

How much would you pay for an amazing, state-of-the-art light bulb? Shoppers will be asking themselves that very question at Home Depot and other outlets starting Sunday Earth Day when the bulb that won a $10 million government contest goes on sale.
The bulb is the most energy-efficient yet, lasts about 20 years and is supposed to give off a pleasing, natural-looking light. But what separates it from the pack most is the price: $60.
That price reflects the cost of the components, especially the top-notch chips, or diodes, that give off the light, and is the price commercial customers will pay. But the manufacturer, Netherlands-based Philips, is discounting it right away to $50 for consumers, and working on deals with electric utilities to discount it even further, by as much as $20 to $30.
This means the bulb will cost anywhere from $20 to $60, depending on where it's found. Online, consumers will be paying $50 for each bulb, because utilities don't subsidize online sales.

On another note a few months ago I bought some Phillips bulbs at Home Depot, they are the crappiest bulbs I have ever bought, they last hardly anytime at all.
.50 to .75
That’s what I used to pay for Sylvania incandescent 4-packs that would last for years and years.
Not intended for use with emergency exit fixtures or emergency exit lights. Not for use where exposed directly to the weather or water. Not for use in totally enclosed recessed fixtures.50,000 hour life; about 2000 days, or just over five years of continuous operation. I wonder how many on/off cycles the bulb is supposed to withstand -- but the box is silent about that. It just says that they assume you use it for three hours at a time, which would come out to around 17,000 cycles.
... complies with FCC Part 15 for a class B device ... generates, uses and can radiate radio frequency energy... Added weight of the device may cause instability ...
Wonder how it stands up to lighting spikes? According the IEEE, the spikes can be as low as 800 volts (ring wave) and as high as 6000 volts (spike, limited by sparking of the clearances in switchgear, fuse boxes and exposed splices) depending on how long with wire is from your fuse box to the light, and other equipment you have connected in your house.
(By the way, the 6000-volt spike can cause the Edison bulbs to explode; one magazine testing lab reported they had one bulb shoot glass everywhere when they applied the test pulse to a turned-on desk lamp.)
And the kicker: "Assembled in Mexico".
Even if it does last 20 years as promised, here’s another reason it’s a really dumb idea: it’s an evolving technology. These bulbs will be wholly outdated in a year or two. Something better and cheaper will be available.
Who would’ve spent $200,000 on a Pentium PC in 1995 because “It’s going to last for 20 years”????
When’s the IPO and how many shares is Comrade Chairman Obama signed up for?
only the trailer, but saw to full movie and is VERY interesting.
I have some good, old-fashioned light bulbs still burning that were in the house when we bought it over 6 years ago.
There IS proof that small LEDs can go at least 10,000 hours or more if you keep them cool. There are probably some running in electronic devices for much longer.
They are easily dimmable and aren’t hurt by frequent on-offs as CFLs are. Do not have the CFL slow start up in cold temps, either.
When China starts producing these they will be super cheap. Who wants a 60 W bulb, though? My old eyes need 100 W. Assuming they are ACTUAL equivalents. I’ve got 100 W incandescents that say 1690 lumens. That’s bright.
Wow, I just saw these at Home Depot and they are 940 lumens. That scale up to about 1565 for 100 W. Not bad.
Might grab one for an outdoor light that I keep on all night. Otherwise, at $50 plus sales tax, I will wait a while.
Also, I am not thrilled with the gummint giving prizes for something that was already going to happen very soon anyway.
Funny thing is, when these get into large scale use, people are going to put a lot more outside. They will also tend to leave them on longer in and out. Some of the savings will be spent. But that’s OK with me.
Years ago, in Illinois, Commonwealth Edison used to give you a supply of light bulbs FREE when you came in and paid your electric bill. Yes...FREE! 60's 100' whatever you wanted.
Green is nothing but a money laundering operation.
I know they're the originals, because it's going to be a major, major pain in the ass changing 'em when they finally go.
What about a 50cent light bulb that lasts for 2 months?
We will know in 20 years or less.
Why would a utility company offer a rebate on a electrical device? Because it saves them from having to supply as much current? Why would a utility company want to reduce an amount of something it’s selling?
Gee....does this mean that all the wild promises about CFLs, and their longevity, were complete lies?
Why else would we need a contest, to build a better light bulb...so soon after we were all led out of the darkness, with the miracle of CFL.
LED tech isn’t quite here yet. The sensible option for light bulb efficiency is high pressure halogens, at the moment.
Actually the trick is lowering the voltage. A typical incandescent will last practically forever if you drop the voltage to half its rating. So instead of looking white it looks orange white. If you look at the super long life incandescent bulbs they are rated for 135 volts or higher instead of 120 where they are normally operated. I don’t remember the exact relationship but I believe it is something like the voltage to the 12th power (or higher) in the reduction of operating time verses voltage increase. Or in other words, voltage makes a huge difference in operating time.
I can get LED bulbs from a farm supply place for about 20 bucks.
