MCPCB-XMLStar-RGBW — Power Meets Precision for Cree XM-L RGBW

Prototype faster with a UL-certified aluminium-core star board engineered for Cree XM-L RGBW.
With high thermal conductivity (2 W/m·K) and ENIG finish, this 20 mm round delivers reliable heat
spreading and easy mounting so you can drive colour and white channels hard while keeping junction temps in check.

• LED footprint: Single Cree XM-L RGBW package (5.0 × 5.0 mm class)
• Die access: Individual pads for R, G, B and W for full per-channel control
• Form factor: 20 mm star, 1.65 mm thick (aluminium base, ENIG)
• Thermal path: Dielectric under LED thermal pad (no direct thermal path)
• Drilling: Optic/holder mounting holes (see optic notes below)

Thermal & Mounting

Thermal Path: Dielectric under the thermal pad of the LED.

For optimal cooling, mount to a flat, clean, finned heat sink (aluminium or copper) exposed to free air.
Recommended attachment methods:

• 20 mm pressure-sensitive, thermally-conductive tape (recommended)
• Thermal compound with mechanical fasteners

The underside is electrically neutral, so isolation from the heat sink is generally not required.
Note: Thermal adhesives make removal difficult; if future servicing is expected, choose a removable TIM.
