XLamp® COB LED Arrays

Cree LED XLamp chip-on-board (COB) LED arrays provide the perfect size, power, performance, and value solution. These COBs feature L90 lifetime and color stability, backed by reliable data. They are available in cool, neutral, and warm white.

The XLamp CHA LEDs are high-intensity metal COBs with small LES. They deliver an outstanding combination of lumen density and efficacy in LES sizes as small as 3.3 mm. CHA family LEDs deliver 50% higher lumen density than the existing XLamp CMU family LEDs for significant improvements in beam angle and intensity. The XLamp CHA family LEDs are also compatible with the available ecosystem of holders and optics designed for high-intensity COBs.

The XLamp CMB LEDs feature drop-in upgrades for Cree LED COB form factors (CXA, CXB, CMA) with the same LES and substrate sizes. They deliver top lumen density and efficacy in Cree LED’s package and LES sizes. Leveraging the latest COB technology platform, the CMB family provides a no-compromise performance upgrade to existing CXA, CXB, and CMA product families while retaining mechanical and optical compatibility.

The XLamp CMU LEDs are second-generation, high-efficacy metal COBs in industry-compatible sizes. They deliver premier performance in commonly available package and LES sizes. The CMU family delivers up to 10% higher LPW than the previous generation CMT family while retaining mechanical and optical compatibility with CMT. XLamp CMU LEDs offer several performance advantages compared with competing LEDs, including higher maximum current, higher minimum flux values, and higher typical efficacy.

XLamp CMA LEDs are metal COBs optimized for efficacy at high current. They deliver superior lumen output, efficacy, and reliability at high drive currents. This metal substrate COB family is highly reliable in footprints and LES sizes compatible with existing CXA and CXB LEDs.

XLamp CXB high-density LEDs deliver high COB lumen density, enabling new lighting form factors for track, spot, and downlights. Fully optimized for maximum intensity, the CXB HD LEDs are an excellent upgrade path from traditional high-candela light sources, including CMH and halogen.

The XLamp CXB standard density LEDs deliver excellent efficacy at lower drive currents and a high level of reliability for COB LEDs through Cree LED ceramic substrates expertise. Featuring a full range of LES sizes, color options, and performance levels, the CXB family provides an easy upgrade path for existing CXA family-based designs.

Pro9™ LEDs deliver up to 15% higher efficacy for 90 CRI and 95 CRI over standard version LEDs without sacrificing color rendering quality. Pro9 LEDs feature a high operating temperature rating of +105°C and the same maximum current as the standard versions. They are available now on the CMB, CMU, CHA, CMA, and CXB LED families.
