XMMRWA-H0-0000-000BK20E1

Cree XLamp® XM-MR 6500 K Cool White LED – E1 K2 Bin

This product is a <strongsingle-bin, single-CCT version of the XLamp® XM-MR family, built around Cree LED’s
highest-flux cool white binning for 6500 K. Using the E1 chromaticity kit and the K2 flux group, part number XMMRWA-H0-0000-000BK20E1 delivers a minimum of 1200 lm at 3000 mA, 85 °C junction, with up to 1276 lm at 25 °C
in a compact 5.0 mm package with a round light-emitting surface (LES).

The round LES improves optical coupling and beam smoothness compared with traditional square-LES emitters, making this
XM-MR variant ideal for portable lights, spotlights and other high-candela applications. It maintains full
footprint compatibility with other XLamp® XM LEDs, allowing easy upgrades to existing XM-based designs without PCB
changes.

Key Features

• Defined, single CCT: 6500 K cool white (E1 chromaticity kit)
• High-flux K2 bin: 1200 lm min at 3000 mA, 85 °C; 1276 lm at 25 °C
• 5.0 mm XLamp® XM package with round LES for superior beam quality
• Binned at 85 °C for realistic operating conditions
• Very low thermal resistance: 0.6 °C/W (junction-to-solder)
• Wide 120° viewing angle for flexible optic pairing
• Maximum drive current: 14 A (with appropriate thermal management)
• Electrically neutral thermal pad
• JEDEC J-STD-020C reflow compatible, RoHS & REACH compliant, UL® recognised component

Electrical & Optical Performance (XMMRWA-H0-0000-000BK20E1)

*Typical value at 25 °C junction temperature.
**Maximum drive current is intended for short pulses (up to 60 s) with suitable thermal design to ensure junction
temperature remains within specification. For continuous operation, select a lower drive current per Cree LED reliability
guidelines.

Mechanical & Thermal Design Notes

• Electrically neutral thermal pad simplifies series/parallel topologies on MCPCBs.
• Use a direct-thermal-path MCPCB and high-performance TIM to take advantage of the 0.6 °C/W R_θJS.
• Follow Cree LED reflow recommendations (JEDEC J-STD-020C) for optimal solder joints and reliability.
• Compatible with common XM-format secondary optics and reflectors.

Typical Applications

• High-performance torches, search lights and headlamps
• Architectural and display spotlights requiring tight, high-candela beams
• Industrial and inspection lighting
• Retrofit upgrades for existing XM-platform designs needing more flux from the same footprint
