Cree, Inc. today announced the introduction of its new XLamp® XP-E4 LED series, featuring industry-leading luminous efficacy for general lighting applications. The new series builds on the success of the popular XP-E2 and XP-E3 families, delivering enhanced performance while maintaining compatibility with existing designs.
Enhanced Performance Specifications
The XLamp XP-E4 series achieves luminous efficacies up to 175 lumens per watt (lm/W) at 350mA and 85°C, representing a significant improvement over previous generations. The LEDs maintain high flux density in the industry-standard 3535 package, making them ideal for applications requiring maximum lumen output in a compact form factor.
Key Specifications
- Maximum efficacy: 175 lm/W at 350mA/85°C
- Maximum flux: 250 lumens at 350mA
- Package: 3.5mm × 3.5mm × 0.85mm
- Color temperatures: 2700K to 8000K
- Typical CRI: Ra > 80 (various options available)
Benefits
- Up to 15% higher efficacy than previous generation
- Improved lumen maintenance over time
- Same footprint as XP-E2/XP-E3 for design compatibility
- Reduced system costs through higher efficiency
- Extended useful lifetime in thermal management applications
Target Applications
The XP-E4 series targets a wide range of general lighting applications where high efficacy and compact size are important. These include:
Downlights
Recessed lighting applications in residential and commercial spaces.
Panel Lights
Flat panel lighting for office and commercial ceiling applications.
Under Cabinet
