COB technology integrates multiple light points into a single chip, eliminating the \"spotting\" effect and ensuring a homogeneous luminous flux of up to 390 lm with low energy consumption.\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\u003eUniform cool white light without spots or points — COB technology evenly distributes luminous flux across the entire 19mm chip surface\u003c\/li\u003e\n\n\u003cli\u003eHigh energy efficiency — up to 150 lm\/W, meaning more light for the same consumption compared to classic LEDs\u003c\/li\u003e\n\n\u003cli\u003eAluminum alloy heatsink included — uniform thermal dissipation through a circular design with slots, without rapid overheating\u003c\/li\u003e\n\n\u003cli\u003eCompatible with a wide range of projects — lighting fixtures, illuminated signs, display cases, and DIY prototypes\u003c\/li\u003e\n\n\u003cli\u003eGel-protected chip — protective layer that reduces the risk of mechanical damage to the LED chip\u003c\/li\u003e\n\n\u003cli\u003eSimple connection with four contacts — two positive and two negative, clearly marked on the support to avoid polarity errors\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 3W COB LED chip is powered by 9V DC with a current of 300mA via an appropriate LED driver — it should not be connected directly to the mains without a driver. Mounting is done on the included aluminum support, obligatorily using thermal paste between the chip and the heatsink, to ensure heat dissipation and optimal lifespan. Connections are made by soldering or clamps on the four polarity-marked pads, checking the power supply voltage beforehand.\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 3W COB LED?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYou need an LED driver that supplies 9V DC at 300mA.
