Description
SFT-25R-WG (CRI > 90) High Power White LEDs
Features
With Luminus’ advanced chip and packaging technologies, SFT-25R-W maximizes the Candela/Lumen K-Factor for high optical performance in directional lighting:
• A small emitter enables high intensity, long beam distance and small optics.
• A patented round emitter, in comparison with a square emitter, enables better uniformity and higher intensity in beam spots.
• A flat window, in comparison with a domed cover, allows the optics to be closer to the emitter to achieve higher intensity and longer beam distance. In addition, Luminus phosphor-on-chip technology’s high uniformity of color over radiation angle enables superior beam spot light quality.
• Package Size: 3535
• Maximum Drive Current: 5 A
• Color Temperature: 5700K
• Color Rendering Index: > 90
• Low thermal resistance: 0.8 °C/W
• ANSI-compatible chromaticity bins
• Electrically isolated thermal path
• 8 kV HBM ESD rating per ANSI/ESDA/JEDEC JS-001
Applications
• Landscape Lighting
• Garage and Canopy Lights
• High / Low Bay Industrial Lighting
• Stage and Studio Lighting
• Stadium and Sports Field Lighting
• Roadway and Outdoor Lighting
