Philips has developed, manufactured and will bring to market an LED replacement for the common 60-Watt incandescent light bulb taking first place in a competition sponsored by the U.S. Department of Energy.
The L Prize is the first government-sponsored technology competition designed to spur lighting manufacturers to develop high-quality, high-efficiency solid-state lighting products to replace the common light bulb.

Every once in awhile gravity takes over and things tumble off my home computer work station. This time my aging Ikea lamp tumbled, did a back flip, missed the cat and met the floor in two pieces.
I took the opportunity to buy a new LED desk lamp that I found at Lowes. The unit puts out a nice white light.
.
The LED array replaces a 35 watt halogen bulb with 3.2 watts of energy consumption. With a 100,000 hours expected life, my lamp could be burning continuously for over 10 years.
About six months ago, I found this interesting clear white LED standard Edison socket bulb for my back porch at Ace Hardware in Manchester. It replaced a 40 watt bulb with a couple watts of consumption.
I recently noticed a wide selection of LED bulbs at Walmart, with specialty bulbs for track lighting.
Most of the currently commercially available LED bulbs will not work on dimmers, but they are out there for a price.
For the seventh year, Judy Brillhart's unique style is featured in the Christmas display at the governor's residence in Harrisburg. Brillhart has a business in North Codorus Township.
The governor's mansion cut expenditures for Christmas decorating in half this year. Brillhart donates her time and materials in exchange for the prominent showcase in this year's holiday tour of the governor's mansion in Harrisburg.
The Rendell administration has also sought to green the mammoth building on Front Street with a total conversion to compact florescent for most fixtures and a geothermal heating system.
Dave Rudolph, the city's electrical bureau superintendent, said 3,000 LED lights will be placed on the tree. That's 500 more than what was used last year.
The city switched to the more efficient lights to save money on its electric bill, Rudolph said. Last year, the city saved about $700.
It also used to cost the city $300 a season for replacement bulbs. The LED bulbs have a ten year lifespan
Projectors have come a long way from huge multi-filament power sucking tungsten bulbs 50 years ago in mechanical movie projectors that weighed the same as a small car.
The waste infrared heat from these bulbs would fry a modern projector. These projectors often had secondary bulbs to read the sound track and power sucking vacuum tubes to interpret the analog sound track image from the film.
Then came digital projectors that shoot light from really expansive exotic bulbs through LCD panels. The bulbs are expensive because they are very precise, have rare materials, and it's a great revenue stream. Replacing the bulb is almost as expensive as the projector and they last about 2000 hours.
Texas Instruments is marketing DLP® picture technology. With millions of tiny mirrors on a single chip, DLP®.
Think LED, cool running, 10,000 hour bulbs with little color decay over the lifespan, and lower power consumption.
A video produced by Texas instruments about the technology, that includes a presentation DLP® projector that can fit in your hand.
Dell began marketing a tiny Texas Instruments DLP® projector, the MS109s, for $499. Which if the bulb lasts $10,000 hours, it would basically be a disposable projector.
The 50 ANSI lumens (maximum) rating seems low when 1,000 lumens is a minimum for leaving the lights up in a small meeting room.
Here is a list of other manufacturers
Maybe someone will buy one and report back to us.
