SST-20-White Specialty LEDs Luminus Devices SST-20-White Specialty LEDs are high-brightness cool white LEDs with a maximum output in excess of 900lm. The SST-20-W LEDs feature a high thermal conductivity package, electrically isolated thermal path, and 120° viewing angle. These white LEDs come with a compact monolithic emitter ideal for directional lighting applications with high uniformity. The SST-20-White Specialty LEDs are available in 5000K, 5700K, and 6500K with 70 CRI (typical) colour points. Applications include horticulture grow lights, automotive light bars, spotlight accessories, headlights, bicycle lights, flashlights, torches, and portable lighting.
