COB (Chip on Board) technology provides a uniform luminous flux of up to 1410 lm from an emitting surface of only 14.8mm in diameter, with no visible light spots. With an efficiency of 140-150 lm\/W, this chip is a solid choice for builders and designers who need real power in a miniaturized format.\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 and dense light — the round surface with protective gel eliminates spots or areas of uneven intensity\u003c\/li\u003e\n\n\u003cli\u003eHigh efficiency of 140-150 lm\/W — consume 10W and get up to 1410 lm, equivalent to a 75-80W incandescent bulb\u003c\/li\u003e\n\n\u003cli\u003eIntegrated aluminum substrate — dissipates heat efficiently and extends the chip's lifespan when properly mounted on a heatsink with thermal paste\u003c\/li\u003e\n\n\u003cli\u003eCompact 19x19mm format — integrates into small spaces without compromising light performance\u003c\/li\u003e\n\n\u003cli\u003eClearly marked polarity — + and - contacts are positioned in opposite diagonal corners, reducing the risk of incorrect connection\u003c\/li\u003e\n\n\u003cli\u003eApplication versatility — compatible with indoor lighting projects, light signs, DIY spotlights, and custom lighting systems\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 operates at 30V DC with a current of 300mA, so it requires an external LED driver to supply the corresponding voltage and current — it does not connect directly to the mains. Installation is done by applying a thin layer of thermal paste between the substrate and the aluminum heatsink, after which the chip is mechanically fixed and the wires are connected to the + and - contacts marked on the corners of the substrate. A heatsink is mandatory: without proper heat dissipation, the junction temperature will rise rapidly and significantly reduce the chip's lifespan.\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\u003eDo I need a separate driver for this LED chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, the chip operates at 30V DC \/ 300mA and requires a compatible LED driver — it does not power directly from 220V.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it mandatory to use a heatsink and thermal paste?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, this chip generates considerable heat at 10W.
