High power LED 3W

soldered on star board
*** The LED must be mounted on a heat sink or heat sink *** The resistance of semiconductors, and thus of LEDs, is strongly temperature dependent. As the LED warms up during operation, we recommend the use of a constant current source. When using a constant voltage source, adjust the voltage so that the current of the WARM LED 750mA or the power consumption does not exceed 3W
