This new generation of the XLamp XT-E platform incorporates key elements of Cree's SC5™ technology platform and now includes a new high-efficiency (HE) option that provides a 25 percent increase in efficacy compared to the previous XT-E LED and offers a guaranteed minimum efficacy of 164 lumens per watt (LPW) at 85 degrees Celsius and 350 mA. These improvements make 130 LPW or more achievable at the system level under good real-world operating conditions, and allow existing customers to quickly improve system performance in applications such as outdoor and industrial lighting, while achieving the lowest total cost of ownership.
The enhanced Cree XLamp XT-E LEDs, available from Mouser Electronics, are optimized for directional, high-lumen applications, from indoors and outdoors to laptops and modern lamps. These high-efficiency XT-E LEDs offer the advantages of the XT-E platform, a compact 3.45 × 3.45 mm package, and established ecosystems, allowing designers to streamline the design process and shorten time to market. Demonstrating the long-term reliability of Cree's high-power ceramic LEDs, the XT-E LEDs now have over 10,000 hours of LM-80 data available, offering L90 lifecycles of over 60,000 hours at 105 degrees Celsius and 1A. XLamp XT-E LEDs are ideal for applications such as outdoor and high-bay lighting that require a long lifespan at high ambient temperatures. The LEDs offer a maximum control current of 1.5A, low thermal resistance of 5 degrees Celsius per watt, and a wide viewing angle of 115 degrees.
