Product Nomenclature > The LUXEON K2 is available in two configurations, one tested and binned at 350 mA and a second tested and binned at 1000mA. Due to production distribution and variance it is difficult to accurately correlate product performance across a broad drivecurrent range. This is one of the reasons Philips Lumileds has elected to offer multiple test current options of the LUXEON K2 tobetter service our customers. The part number designation is explained as follows:L X K 2 A B C D E F G for LUXEON K2 Emitter L 2 K 2 A B C D E F G H for LUXEON K2 StarWhere:A designates radiation...
