Cree Inc. (Durham, NC) has added 80, 85 and 90 color rendering index (CRI) options to its XLamp® XP-G and XP-E warm white LEDs. 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. The new options satisfy the need to maintain high light quality and system efficacy, the company reports. The new high-CRI XP-G is available with luminous flux of up to 107 lumens at 350mA in warm white (3,000K), 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, the company says.
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 Eenergy Star®, are UL-recognized components under UL 8750 (E326295).
High-CRI XP-G and XP-E LEDs are available in sample and production quantities with standard lead times. To locate a distributor, visit www.cree.com/buyxlamp.
