30th November 2011 —DURHAM, N.C., October 25,
2011 — Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces
the commercial availability of high-voltage XLamp® XT-E and XM-L LEDs. These
new LEDs can enable the use of more efficient, smaller drivers to lower cost
for compact lighting applications such as candelabras and retrofit lamps.
“The XLamp XM-L High-Voltage LED eliminates the trade-off between size and
efficacy, allowing us to take advantage of the efficacy of high-voltage
drivers,” said Ken Chakravarti, chief technology officer, Ledzworld. “This
translates to more efficient, better and more cost-effective small LED lamps
and luminaires such as the B10 replacement lamp for our customers.”
Small-form-factor lighting, like candelabras, historically presented a host
of challenges for LED technology. Prior LEDs were unable to deliver the
required system-level performance in the form factor consumers’ demand.
“Maximizing the LED voltage, as Cree has done in the new high-voltage XM-L
and XT-E LEDs, is a very effective way to minimize current through the LED
driver output rectifier,” said Peter Vaughan, director of applications
engineering, Power Integrations, Inc. “This can reduce losses and heat
dissipation in the driver and increase the overall system luminous efficacy
by several percentage points.”
“Never before have lighting OEMs been able to leverage the benefits of
high-voltage LEDs with this level of performance,” said Paul Thieken, Cree
director of marketing, LED components. “We continue to develop the right
LEDs for the right applications—to accelerate the adoption of
energy-efficient LED lighting.”
The XLamp XM-L LED delivers up to 600 lm in Cool White (6000 K) and up to
462 lm in Warm White (3000 K) at 6 W, 85°C. The XLamp XT-E LED delivers up
to 300 lm in Cool White (6000 K) and up to 228 lm in Warm White (3000 K) at
3 W, 85°C. Both LEDs have a typical voltage of 46 V at binning conditions.
XLamp XT-E and XM-L LEDs are available now in production quantities with
standard lead times. For more information about Cree high-voltage LEDs,

performance criteria.
“When we set out to build our new linear light engine, we required the efficacy
and reliability of XLamp LEDs, but wanted a smaller package size,” said Markus
Vockenroth, managing director, MAL Effekt-Technik GmbH. “The XLamp ML-E LED was
the perfect combination of price and performance for our application.”
The XLamp ML-E delivers lighting-class performance in applications where a
smooth, uniform appearance is required, such as LED fluorescent-tube
replacement, ceiling-mounted panel lights and under-cabinet lighting. Unlike
other low-power LEDs originally developed for consumer electronics and
backlighting applications, the XLamp ML-E delivers the segment-leading color
binning, efficacy, thermal resistance and the long-term reliability required for
ENERGY STAR® luminaires and bulbs.
“The ML-E offers the lighting design community a simple and affordable solution
for a major portion of the solid-state lighting market,” said Paul Thieken,
Cree, director of marketing, LED Components. “Designers of applications like
fluorescent-tube replacement no longer need to settle for LEDs that aren’t
lighting-class.”
The XLamp ML-E delivers full-size features in a small, affordable package with
luminous flux of up to 58 lm at 150 mA in cool white (5000 K) and up to 48 lm in
warm white (3000 K). Like the XLamp MX-6 and MX-3 LEDs, the ML-E provides a
tightly controlled uniform angular chromaticity and a 120-degree viewing angle,
optimized for distributed lighting applications. The XLamp ML-E also shares the
same ANSI-compliant chromaticity binning used by the XLamp XP and MX families of
LEDs.
XLamp ML-E LEDs are available in sample quantities immediately and in production
quantities with standard lead times.
12th April
2010 — Cree, Inc. (Nasdaq: CREE), a market leader in LED
lighting, announces a breakthrough new lighting-class LED platform, the
XLamp® XM LED. This new single chip LED delivers record-breaking efficacy of
160 lumens per watt at 350 mA. The LED also delivers 750 lumens at 2 A,
which is equivalent to the light output of a 60 W incandescent light bulb at
less than 7 watts.
“This new platform continues Cree’s well-established record of turning R&D
innovations into products,” said Chuck Swoboda, Cree chairman and CEO. “We
continue to set the pace for LED performance, establishing new benchmarks
that make you wonder why anyone would consider last-century’s energy-wasting
technology.”
A cool white XM LED driven at 350 mA can produce 160 lumens at 160 lumens
per watt. The new platform has a larger footprint than Cree’s XP family and
also offers the unique combination of very high efficacy at very high drive
currents. At 2 A, an XM LED produces 750 lumens at 110 lumens per watt. The
thermal resistance of the XM platform is 2 degrees C per watt— an
industry-leading technology breakthrough and a 350 percent improvement over
Cree’s flagship XLamp XP-E LED.
Samples of the XLamp XM LEDs are available for order with standard lead
times and commercial availability is targeted for Fall 2010.

With increased emphasis on energy efficiency, developers are being asked to
go a step further in planning future subdivisions. In planning the Morning
View subdivision in the NSW town of Quirindi the developer; Independent
Group Australia investigated an environmentally friendly option of solar
street lighting for their estate. With the blessing of Liverpool Plains
Shire Council IGA contacted Weidemuller NSW to design and manufacture custom
LED luminaires which would operate as stand alone units powered by solar
panels on specially designed Vicpole poles. The result is the first P5 rated
LED stand alone street lights using the Cree XR-E Power LEDs, to be used in
a residential subdivision in Australia – quite an achievement. Apart from
zero carbon emissions, it’s said the LED’s have a life expectancy of 50,000
hours and the solar panels are self cleaning. From all reports, the poles
and lights which were installed in July 2007, are “working perfectly”.
