The COB (Chip on Board) format ensures a uniform luminous flux of 2000-2100 lm from a compact 43x43 mm source. It is the right choice for electronics technicians and engineers who repair or assemble LED lighting fixtures.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-benefits\"\u003e\n\n\u003ch2\u003eWhat you get with this product\u003c\/h2\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eComfortable, warm light of 3000-3500K — suitable for residential areas, workshops, and ambient spaces where cool light would be tiring\u003c\/li\u003e\n\n\u003cli\u003eLuminous flux of 2000-2100 lm at only 20W consumed — high efficiency\/power ratio for a chip of this size\u003c\/li\u003e\n\n\u003cli\u003eCompact COB construction (43x43 mm) — easily integrates into standard projectors or custom builds without major frame modifications\u003c\/li\u003e\n\n\u003cli\u003eStable 32-34V DC power supply voltage — compatible with medium-power LED drivers available on the market\u003c\/li\u003e\n\n\u003cli\u003eQuick replacement of the defective chip — extends the lifespan of the projector without needing to purchase an entire new fixture\u003c\/li\u003e\n\n\u003cli\u003eGeneral purpose OEM component — usable in industrial, commercial, or DIY lighting applications at a low cost per lumen\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-how\"\u003e\n\n\u003ch2\u003eHow it works and how to install it\u003c\/h2\u003e\n\n\u003cp\u003eThe COB LED chip is glued or mechanically fixed to a suitable metal heatsink, and thermal paste must be applied between the chip and the heatsink for heat dissipation — without proper cooling, the lifespan is significantly reduced. Connection is made directly to an LED driver with a 32-34V DC output and current corresponding to the 20W power; it should not be powered directly from the mains. The operation requires basic electronics knowledge — soldering, polarity identification, and the use of an appropriate LED driver.\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 20W chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYou need an LED driver with a 32-34V DC output voltage and a current of approximately 600-650mA, so that the total power fits within 20W.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a heatsink for this COB chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, a heatsink is mandatory.
