This document summarizes the key specifications and simulation results for an LED lamp component. It includes the part number, manufacturer, operating temperature range, equivalent circuit diagram, and graphs comparing the measured and simulated forward current, luminous intensity, reverse current, and reverse recovery characteristics. The simulation results match the measurement data well with less than 1% error across most of the operating ranges tested.
