Cree Prototypes 1,000+ Lumen LED chip

Cree breaks 1000 Lumens on a single die!

The next post should be about LED Grow Light bench power supplies that can handle the additional power requirements of the emerging next generation solid state lighting chips.

With a driving current of 4A, the company's prototype, single-die LED delivers a light output of 1,050 lumens in cool white, a level comparable to a standard incandescent bulb, and 760 lumens in a warm-white version.

As a result, the company claims this breakthrough may lead to the development of LEDs that will make traditional light bulbs obsolete.

Efficacy of the cool-white LED is 72 lumens/Watt and, for the warm-white device, 52 lumens/Watt.

Both versions allegedly operate at significantly higher efficacy levels than conventional light bulbs.

Cree Offers Breakthrough 100-Lumen XLamp LEDs

Things are starting to heat up in Solid State Lighting again!

Cree, Inc. (Nasdaq:CREE), a market leader in LED solid-state lighting components, today announced commercial availability of XLamp(r) LEDs with minimum luminous flux of 100 lumens at 350 mA. XLamp LEDs are the first LEDs to be available in volume with this level of performance. This advance sets a new standard in lighting-class LED brightness and efficiency.


XLamp LEDs have now achieved a 100% improvement in performance over the past 17 months. They can deliver either 25% greater brightness with improved efficacy, or they can deliver up to 55% greater brightness at the same efficacy when compared to the previous generation of XLamp LEDs. Moreover, the new XLamp LEDs retain the same footprint as previous XLamp LEDs, thereby protecting customers' design investments.

"Cree is to be congratulated on surpassing the 100-lumen level in its commercial white LED products," said Robert Steele, director of the optoelectronics practice at market research firm Strategies Unlimited. "The availability of such high-performance devices should certainly accelerate the conversion of the lighting market to solid-state sources."

"This is an announcement of volume availability, not an R&D result or availability of a few parts," stated Norbert Hiller, Cree vice president and general manager for lighting LEDs. "These LEDs can enable lighting manufactures to create fixtures using fewer LEDs than before, thereby lowering initial product cost and reducing energy consumption."

New Blue 'EZBright 700' LEDs from Cree

New EZBright(TM) 700 LED Power Chip Broadens Cree's High-Performance Chip Platform

Helping push the Solid State LED Grow Lighting industry forward, Cree, a leader in LED solid-state lighting components, today announced the release of its newest blue EZBright LED power chip. The EZBright 700 LED is the latest blue chip product based on Cree's flagship proprietary EZBright LED platform, which continues to set performance standards across a broad range of the LED marketplace. The EZBright 700 is the brightest, most cost-effective LED chip of its size with dominant wavelength bins covering ranges from 450nm to 470nm.

The EZBright 700 achieves a typical output of 260 mW at 350 mA and 440 mW at 700 mA. It is targeted for general lighting applications, including auto headlamps, streetlights, camera flash, projection lighting, personal lighting and indoor and outdoor display applications. The EZBright platform features a proprietary optical design that delivers an optimal Lambertian radiation pattern with reduced emission losses and high efficiency compared to Cree's other LED chip platforms. This high-efficiency design scales well with the size of the chip, a significant achievement for the industry.

"Cree recognizes the market need for high performance at low cost across a range of lighting applications," stated David Davito, Cree director of marketing for optoelectronics. "With the mid-size format EZBright 700, we're expanding the EZBright line to address a broader range of lighting markets."
