 Shatters Single-Die Performance Standards

The XLamp XM-L is the industry’s brightest, highest performance lighting-class LED. With breakthrough light output and efficacy, XM-L is designed for very high-lumen applications such as high-bay or roadway lighting.

XLamp XM-L LEDs offer the unique combination of very high efficacy at very high drive currents, providing a 20% efficiency gain over the XLamp XP-G LED at the same current. With this available efficacy, XM-L can lower total system cost by reducing the number of LEDs and optics in the system.

Features

  • Delivers 160 Lumens per Watt at 350mA, and 1000 lumens at 100 lumens per Watt at 3A
  • Low thermal resistance: 2.5°C/W
  • ANSI-compatible chromaticity bins
  • Unlimited floor life at ≤ 30ºC/85% RH
  • Reflow solderable - JEDEC J-STD-020C
  • Electrically neutral thermal path

                       

Lighting Applications

  • Street and roadway
  • Outdoor area
  • High-bay and industrial

Cree Leds on Printed Circuit Boards




 

13th February 2013:  Cree Sets New R&D Performance Record with 276 Lumen-Per-Watt Power LED DURHAM, NC -- Cree, Inc. (Nasdaq: CREE) delivers another industry first with a barrier-breaking 276 lumen-per-watt white R&D power LED. This significant milestone exceeds Cree’s previous R&D industry record of 254 lumens per watt and demonstrates Cree’s continued commitment to innovate and accelerate the adoption of LED lighting.

Cree’s innovative SC³ Technology™ Platform, available today in Cree XLamp® LEDs, enables this record-breaking R&D result. The SC³ Technology Platform features advancements in LED chip architecture and phosphor and boasts a new package design to deliver the most advanced LED components in the industry.

Cree reports that the LED efficacy was measured at 276 lumens per watt, at a correlated color temperature of 4401 K and 350 mA.

“The core of the Cree R&D culture is a relentless focus on innovation that ultimately drives LED adoption,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “The innovation from our labs is the foundation for our lighting-class XLamp LEDs. Higher-performance LEDs can enable new and better LED-based applications and drive down the solution cost of LED designs.”

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 applicationsto 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, 85C. 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, 85C. 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, please visit www.creehighvoltage.com.
