Mounting is done by adhering the chip to an additional heat sink or a metal surface with thermal paste, which is mandatory for dissipating the heat generated at high power. It should not be connected directly to the mains without a driver and should not be exposed to humidity or excessive heat sources.\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\u003eWhat driver do I need for this 7W COB LED chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eAn LED driver with a 21V DC output and a constant current of 300mA is required, dimensioned for a power of at least 7W.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the chip absolutely need a heat sink or can it run without one?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, a heat sink and thermal paste are mandatory.
