Connection is made based on the plus and minus markings on the star-shaped heatsink, without additional components if you use an appropriate LED driver. For stable operation at maximum power, it is recommended to apply thermal paste between the heatsink and the surface you are mounting it on, although the integrated heatsink already provides sufficient basic cooling for normal use.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-faq\"\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a special driver for this 3W LED chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, a constant current source of 500-700 mA at 3.2-3.6V is required.
