Bulb will debut at $50; nobody said "perfection" was cheap

Nearly four years have passed since the U.S. Department of Energy (DOE) announced the "L Prize", a $20M USD reward to the first company who successfully produced a light-emitting diode (LED) bulb meeting a special set of criteria in terms of energy efficiency and lighting performance.  The prize took money from allocations made by the Energy Independence and Security Act (EISA) of 2007, signed into law by former President George W. Bush.

I. Koninklijke Philips Wins the L Prize

The years have passed and at last there is a winner.  The prize has been awarded to a design from Koninklijke Philips Electronics N.V. (AMS:PHIA), an Amsterdam, Netherlands-based global electronics company.

The winning design is dubbed the "Philips Award Winning LED Bulb".  Its specs easily meet the L Prize criteria:

A video on the testing process is seen below:



The Philips bulb survived all the tests, emerging with flying colors.  It did particularly well in longevity testing, showing almost no performance degradation after predicted at 25,000 hours (1041 days, or almost 3 years of continuous operation).

II. For $50 is the L Prize Bulb Worth It?

The bulb trims over 2.5W off Philip's previous generation LED bulb designs, a power savings of roughly 20 percent.  Unfortunately those savings come at a cost -- where as Philip's previous generation models are retailing for around $33 USD, the new bulb retails for $49.95 USD, nearly 50% more expensive.  The bulb is assembled in the U.S. from components manufactured in Shenzhen, China with LED chips made in San Jose, Calif.

The pricey bulb has a 29 percent wall-plug efficiency ratio -- compared to the 60W incandescent lamp’s 12% and a CFL’s 19% wall-plug efficiency.  The new design delivers 90 lm/W (an efficiency measure) –compared to an average 60W incandescent with about 13 lm/W or a CFL with about 53 lm/W.

Detailed information about its color and luminosity performance is available here [PDF], direct from Philips.

The bulb carries a distinct yellowish hue when powered off, but Philips assures that the "remote phosphor" (yellow) disappears when the bulb is powered on.  The emitted light is white with a slightly yellowish hue (as with the standard off-the-shelf incandescent bulbs).

Philips is offering a 3-year warranty on the bulb.  And it rates it at 30,000+ hours of life.

Given a $0.10 USD per kWH cost of electricity -- a "middle of the road" scenario in the U.S. [source] -- the bulb would save approximately $150 USD over its lifetime ($0.10 USD/kWh * 3e4 h * 0.050 kW) versus an incandescent design.  However, the additional 2.5 watts of power savings over previous generation models only represents approximately $7.50 USD more in savings.

Aside from the cost savings, the LED lights also offer smoother dimming than incandescent bulbs, with less impact on longevity.  And unlike compact fluorescent lighbulbs (CFLs), a rival energy efficient design, they lack toxic compounds like mercury.

Thus the bulb may be sought after by LED lighting enthusiasts, but will likely be overlooked by businesses, which would tend to prefer cheaper, more mature LED designs.  However, the technology should eventually fall into line with current generation models price-wise, offering the best of both worlds.

We're still a long way from the promises of some LED researchers -- a 60-year light bulb that costs $2.85 USD -- but the industry is starting to get to the point where LED lighting makes sense for businesses and consumers from a financial perspective.

You can order the bulb from various sources, such as Light Bulb Emporium.  It should ship in March.

For its win, Philips receives $10M USD, and free promotion from the DOE.  The DOE still has more money to give to other L-Prize winners.

Note:
Be careful when browsing sites or shops looking for this bulb as there's many different models out here.  Note this is the <10 W Endura series model.  This should not be confused with the last-gen 12.5W Endura series model (linked above) or the (last-gen) 8W Ambient Light series.

Note 2:
While the bulb design was an international effort based on the multi-national Koninklijke Philips company, the award winning design was submitted by Philips Lighting North America, who will be producing and marketing the bulb in the U.S.

LED's DO put out the right amount of light! You have to buy the right one's though. My biggest aggravation with this whole BS green "movement" crap is the blatant misinformation being put out. They turn people off by assuming they're stupid and giving them crap info and crap products to choose from! And when people figure out they've been duped they trash the whole thing, good or bad. It infuriates me! Now I'm pissed.

1. Do as I say, not as I do. I HAVE to drive a Prius while it's perfectly ok for you to ride in limo's and fly private jets everywhere? Really? How about you kiss my ass.

2. You drive a SUV or pickup, don't you care about the environment? Listen, I was driving 4 cyl cars, turning off unnecessary lights, setting my thermostat to 80 in the summer, recycling, wearing used clothes, buying local, etc LOOONGGG before you assholes sold YOUR SUV's and started "caring" about the environment. How about you kiss my ass.

3. Don't you think that house you live in is a little big for just the two of you? And why do you live so far from work? You could save resources by living in an apartment in the city and walk or ride a bike to work. Well, I like my space and I hate living next door to assholes. Housing is cheaper in the boons and the neighbors are friendly. Ride a bike? I might be wrong but I don't think a Chevy Suburban is a bike which is what you were driving before you got all conscious on a nigga. And when I go to your house, why are all your bathroom lights and TV's on? Weren't you bragging about how big your house was two years ago? How about you kiss my ass.

4. Europeans. LOVE the time I spent there. Nice, friendly people. And they definitely know how to have a good time for sure. Bend your ears this way for a minute. Our culture is not the same as yours. Period. We're not interested in a welfare state. Period. We don't want public healthcare. Period. Stop watching our TV and thinking that's what we think. It's not. Period. You guys are hypocrites for crapping on us because we want to enforce immigration laws yet your immigration laws are extremely strict. What goes on here would never fly in any of your countries. Hell, even the most ardent anti-illegal immigration folks in the US don't want ALL or even MOST illegals deported. It's not practical. So mind your friggin business. And kiss my ass.
