Cree XLamp XP Series
XLamp XP series combines the proven lighting-class performance of the XLamp XR-E LED with an ultra-compact, optically centred package. Available in three variants, XP-C for cost-sensitive applications, XP-E for premium performance with tight colour binning and XP-G for ultra-efficient performance at a high forward current, the XLamp XP family gives lighting manufacturers a wide range of price and performance options that all share a common footprint.
XP-C is targeted to be a lower cost option, and as such comprises a smaller LED die. The net result is an inexpensive LED offering both excellent colour stability and impressive lumen maintenance. The maximum forward current for XP-C is 500mA.
XP-E is a versatile lighting-class LED emitter, offering superior lumen output from a smaller LED package when compared the XR-E. XP-E is available in cool, neutral and warm white colour temperatures and is now available in a full gamut of monochromatic colours, including red, amber, green, blue and royal blue.
XP-G is targeted at high-performance applications necessitating significant lumen output and efficiency. For example, when driven at 350mA the cool white XP-G product is capable of achieving a lamp efficacy of 130 lumens per Watt, which is 64% more efficient that the highest performance XR-E LED.
Recent developments to the XP-G product include the availability o the product in neutral and warm white colour temperatures. Additionally Cree has advised a fully retrospective revision of XP-G’s maximum forward current, increasing the maximum rated value to 1500mA when used in conjunction with appropriate heat sinking.
