Cree recently announced the addition of 80, 85 and 90 colour rendering index (CRI) options to its XLamp XP-G and XP-E warm-white LED series. Many lighting applications, such as retail, medical and architectural, require high colour accuracy to properly render object colours.
With previous-generation high-CRI white LEDs, increasing colour quality meant decreasing efficacy. With the new high-CRI XP-G and XP-E, luminaire and fixture designers can have both. The new high-CRI XP-G is available with luminous flux of up to 107 lumens at 350 mA in warm white (3000 K), providing efficacy of 102 lumens per watt. Using this new XP-G, Cree says LED lamp designers can create systems that are 70% more efficient than a traditional halogen PAR38 lamp and deliver similar high colour 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-recognised components under UL 8750 (E326295), and feature excellent thermal management properties.
