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, please visit www.creehighvoltage.com.
