Philips Wins $10M USD Gov't L-Prize for World's Most Efficient Light Bulb
February 27, 2012 10:54 AM
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 "
", 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. (
), 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
[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. [
] -- 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.
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.
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.
