This tiny little pill sized light bulb from the folks at Luxim, emits ’sun spectrum light’ and at the core of the bulb radiates the same heat level, 6,000 Calvin. That’s 140 lumens per watt - 15 lumens per watt for a regular light bulb and 70 for an LED - and converts most of its energy into actual light, unlike most lights which convert it into heat. How does it accomplish this feat? $40 million in VC funding of course.
LIFI leads a new class of solid-state high-intensity light sources that combine the best features of solid-state electronics and full spectrum plasma emitters. The results are long-life, energy efficiency and complete color spectrum for lighting applications like general and specialty lighting and projection displays like wide screen HDTVs and projectors.LUXIM's LIFI™ technology provides superior performance for high definition projection televisions and home theater projectors using DLP™, transmissive LCD and LCoS microdisplay technologies.
Specialty lighting includes LIFI applications like medical and analytical instrument lighting. Endoscopy, microscopy and other equipment are made possible with the highest level of color rendering available from a long life light source.
LIFI brings together the best qualities of solid state electronics and plasma based emitters in a high intensity light source capable of more than 140 lumens per watt. This efficacy combined with 20,000 lumen output per source make LIFI ideal for applications in entertainment, industrial, architectural, area and street lighting.

In September 2007, Cree Inc, announced it had demonstrated light output of more than 1,000 lumens - an amount equivalent to the output level of a standard household light bulb - from a single R&D LED.
Cree’s achievement demonstrates continued leadership in the development of LEDs that can make traditional light bulbs obsolete.
A single-die LED, driven at four amps, produced 1,050 lumens in cool white and 760 lumens in a warm-white version. Efficacy of the cool-white LED was 72 lumens per watt and 52 lumens per watt from the warm-white device. Both LED versions operated at substantially higher efficacy levels than those of today’s conventional light bulbs. Historically, Cree’s R&D demonstrations generally have been commercialized within 12 to 24 months.
“Cree’s XLamp® LEDs are the best-performing commercially available LEDs, but we won’t be satisfied until light bulbs are obsolete,” comments John Edmond, Cree co-founder and director of advanced optoelectronics. “We’ve worked 20 years to achieve lighting-class LED performance, and we still have plenty of ways to advance the technology further.”

MARCH 3, 2008 — Cree, Inc. (Nasdaq: CREE), a market leader in LED
solid-state lighting, today announced that it has completed the
acquisition of privately held LED Lighting Fixtures, Inc.
This acquisition expands Cree’s market opportunity by providing direct access to the lighting market. Cree's business now encompasses LED chips, components and lighting solutions. It further enables Cree to drive retrofit solutions to convert existing lighting infrastructure to energy-efficient lighting and to accelerate the adoption of LED lighting.
“We are out to lead the LED lighting revolution and to obsolete the lightbulb,” said Chuck Swoboda, chairman and chief executive officer of Cree.
Cree is a market-leading innovator of lighting-class LEDs, LED lighting retrofit solutions, and semiconductor solutions for backlighting, wireless and power applications.

“To replace traditional light sources, LEDs need to
provide both high light output and high efficacy,” comments John
Edmond, Cree co-founder and director of advanced optoelectronics. “Cree
continues to push the limits of LED performance in order to realize the
potential of the LED lighting revolution - energy-efficient,
long-lasting LED light.”
These are the best results reported for packaged, high-power LEDs, and indicate that Cree is extending its lead in solid-state lighting through its continued investments in LED technology.
The results have been verified by the National Institute of Standards and Technology (NIST). NIST’s tests confirmed that the cool-white (5,813 K) LED produced 135.7 lumens of light output and achieved 129 lumens per watt efficacy. The warm-white (2,950 K) LED produced 104.2 lumens of light output and achieved 99 lumens per watt efficacy. The institute tests LEDs at 350 mA and measures the output after five minutes of operation to ensure thermal stabilization.
In coming years, such investments in core LED technology could lead to products that replace traditional light sources in all commercial applications.
