Description
SFT-40-WES Gen 2 High Power White LEDs
Features
SFT white series is a powerful light source for beam pattern critical lighting applications. The flat window of an SFT white LED results in a much smaller light emitting surface than a dome-shaped cover, enabling smaller optics and higher optical efficiency in directional lighting systems.
• Vertical chip with high lumen density and small emitting angle, ideal for efficient optical beam shaping to achieve high intensity, narrow beam angle and long beam distance.
• Phosphor-on-chip with superior color uniformity over radiation angles, delivering homogeneous color in beam spots.
• Maximum Drive Current: 8 A
• Color Temperature: 5000K, 5700K, 6500 K
• Color Rendering Index: Typ. 73 (5000K, 5700K), Typ. 70 (6500K)
• Low thermal resistance: 0.7°C/W
• ANSI-compatible chromaticity bins
• Electrically isolated thermal path
• 8 kV HBM ESD rating per ANSI/ESDA/JEDEC JS-001
Applications
• Portable Lights
• Bicycle Lights
• Automotive Auxiliary Lights
• LED Work Lights
• Outdoor and Roadway Lighting
• High Bay Industrial Lighting
• Entertainment Lighting
• Directional Light Fixtures
