Lumileds' LUXEON XR-M products are LED modules optimized for lighting applications requiring high-power LED arrays, mounted on a rigid and thermally conductive substrate. These versatile building blocks come with three, four, or five LUXEON M LEDs on a MCPCB substrate and are designed for ease-of-system integration, faster time-to-market, and use with industry-standard optics. The 2 x 2 square version will become a complete IP66 solution when used in combination with standard third-party optics and heat sink.
