by Ann Withanee — November 5, 2010—Cree, Inc., a market leader in LED lighting, announces the addition of 80, 85 and 90 color rendering index (CRI) options to its XLamp XP-G and XP-E warm white LEDs and points out that many lighting applications, such as retail, medical and architectural, require high color accuracy to properly render object colors.
With previous generation high-CRI white LEDs, increasing color quality meant decreasing efficacy. Thanks to the new high-CRI XP-G and XP-E, luminaire and fixture designers can have both, promises Cree.
The new high-CRI XP-G is available with luminous flux of up to 107 lumens at 350mA in warm white (3000K), providing efficacy of 102 lumens per Watt. Using this new XP-G, LED lamp designers can create systems that are 70 percent more efficient than a traditional halogen PAR38 lamp and deliver similar high color rendering.
High-CRI XP-G and XP-E LEDs are similar to standard XP-G and XP-E LEDs, respectively, and may work in existing systems without any redesign. Just as with the standard XP-G and XP-E, the new LEDs have LM-80 data approved by ENERGY STAR, are UL-recognized components under UL 8750 (E326295), and feature excellent thermal management properties.
High-CRI XP-G and XP-E LEDs are available now in sample and production quantities with standard lead times.
