It is intended for DIY projects, decorative lighting, and stage applications where color control is essential. The COB format with an aluminum base ensures good thermal dissipation even at small dimensions.\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\u003eThree independent colors in one chip — red, green, and blue controlled separately for free color mixing\u003c\/li\u003e\n\n\u003cli\u003eCompact 28mm COB format — easily integrates into custom luminaires, spotlights, or electronic projects\u003c\/li\u003e\n\n\u003cli\u003eStar-shaped metal base for secure mounting and efficient thermal transfer to the heat sink\u003c\/li\u003e\n\n\u003cli\u003eLow consumption of 3W with visible and intense light emission on each color channel\u003c\/li\u003e\n\n\u003cli\u003eCompatible with standard RGB drivers and controllers — no special, hard-to-find components required\u003c\/li\u003e\n\n\u003cli\u003eRobust construction with protective silicone coating of the chips — good resistance to handling and vibrations\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 RGB COB LED chip has three separate anodes for red, green, and blue, and a common cathode, with connections made by soldering or clamps on the marked pads on the metal base. For proper operation, a constant voltage power supply suitable for each channel and a heat sink applied to the back of the aluminum base, secured with thermal paste, are required. Prolonged operation without a heat sink is not recommended, as excessive temperature can damage the chip.\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 supply voltage does each channel of this RGB chip require?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe red channel generally operates at forward voltages of 2.0–2.4V, and the green and blue channels at 3.0–3.4V; the recommended current per channel is approximately 350mA for the nominal power of 1W per channel.\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 heat sink for this 3W COB LED?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, the use of a heat sink with thermal paste is mandatory for stable operation and a long lifespan; without adequate cooling, the junction temperature rises rapidly, and the chip can degrade.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I get white light with this RGB LED chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eAn approximation of white light can be obtained by simultaneously activating all three channels at equal intensity, but the result will not be identical to a dedicated white LED due to differences in efficiency between channels.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-specs\"\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eSKU\u003c\/td\u003e\n\n\u003ctd\u003eQ-20C063\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eType\u003c\/td\u003e\n\n\u003ctd\u003eCOB RGB LED Chip\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eTotal Power\u003c\/td\u003e\n\n\u003ctd\u003e3W\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eEmitted Colors\u003c\/td\u003e\n\n\u003ctd\u003eRed, Green, Blue (RGB)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eChip Diameter\u003c\/td\u003e\n\n\u003ctd\u003e28mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eConfiguration\u003c\/td\u003e\n\n\u003ctd\u003eCommon Cathode \/ Three Independent Anodes\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eBase\u003c\/td\u003e\n\n\u003ctd\u003eStar-shaped Aluminum\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eBrand\u003c\/td\u003e\n\n\u003ctd\u003eOEM\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003ePackage Contents\u003c\/td\u003e\n\n\u003ctd\u003e1x 3W 28mm RGB COB LED Chip\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-warranty\"\u003e\n\n\u003ch2\u003eWarranty and support\u003c\/h2\u003e\n\n\u003cp\u003eThe product benefits from a 2-year legal warranty in accordance with current Romanian legislation.
