So you either need a 15V+ constant-voltage supply with an appropriate wire-wound or ceramic power resistor, or you need a constant-current Led driver power supply that has a minimum compliance of 15V adjusted to deliver P/E = 3/ = A. The LED will continue to get hotter and draw more current until the LED burns itself out, this is also known as Thermal Runaway. The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED(s).How to Build a 32V, 3 Amp LED Driver Circuit
