Cree LED Pro9™ LEDs leverage innovative KSF or PFS to improve LED device efficacy, setting a new technical benchmark for high-color rendering index (CRI) LEDs (9095). Cree LED pioneered the use of KSF phosphor in high-power and high-efficacy LEDs, and was the first supplier to successfully apply this phosphor to high-power ceramic LEDs.

Technological Breakthrough Revolutionary Application of KSF Technology
Boosting Both Luminous Efficacy and Color Rendering
Pro9™ utilizes KSF to optimize spectral distribution, achieving a 15% improvement in luminous efficacy at CRI 9095. Compatible with standard package dimensions, drive current, and electrical parameters, the Pro9™ LEDs eliminate the need for redesign, maintaining high efficiency and reducing production costs.
Harsh Environment Resilience
Up to 105°C operating temperature Industry-leading high-temperature resistance ensures stable output in high-temperature and high-humidity environments.
Intelligent Spectral Adjustment
Provides dual modes Standard (BBL reference) and Below BBL, respectively adapted for high and low temperature environments
Standard mode Stable white balance at high temperatures;
Below BBL mode Optimized white balance at low temperatures.
