Answer: No, it cannot be used directly in the car, it needs a matching converter to use Q: Can 3w directly use 12v? Answer: No, 3w (DC9-10V working voltage) you need a constant current driver to use DC12V. If you use DC12V directly, the temperature will be too high, and the lamp beads will be burned. Q: Do I need an extra heatsink? and LED driver? Answer: The chip is very hot when it is working, and it needs an additional heat sink and a constant current drive to work.
