COB technology combines multiple emission points into a single chip, providing a uniform luminous flux of up to 2050 lumens at only 15W consumption.

Mounting is done on an aluminum heatsink with thermal conductive paste applied between the chip and the heatsink surface, to efficiently dissipate the heat generated at high power. The two power contacts are positioned in diagonal corners, marked with plus and minus, and are soldered or connected via clips according to the indicated polarity.\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 LED driver is compatible with this 15W chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eA driver with a 45V DC output and a constant current of 300mA is required.
