Versatile lighting options in the small, proven ML package
• Reliable package: LM-80 data available now– ML-B @ 80mA & 175mA (soon); ML-C @ 116 mA; ML-E @ 175 mA
• Wide variety of CRI & CCT options in a common footprint– Min 80 CRI: 2700K to 7000K;
– Min 85 & 90 CRI;
– 2200K CCT matches dimmed halogen (ML-B)
• ML-E & ML-C available in series voltage configurations– Higher LED string voltage can improve LED driver performance and cost
for line-voltage lighting applications

XLamp ML Lamp Application: 450 lm A19
• ML-C series enables higher LED string voltage– Better LED driver efficiency with higher system voltage
• ML-E series enables lower LED count– LEDs can be placed lower in the neck of the LED bulb, more omni-
directional
• LM-80 data readily available for the ML familyCopyright © 2012, Cree, Inc. pg. 6
