With a luminous flux of 600 lumens at only 5W consumed, this COB module represents a compact and efficient light source for building or replacing existing light sources. The aluminum alloy backing ensures heat dissipation directly from the source, extending the chip's lifespan.\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\u003e600 lumens from a module of only 20mm diameter — high light density in a minimal space\u003c\/li\u003e\n\n\u003cli\u003eCool white light at 6500K, ideal for functional lighting, workshops, display cases, or floodlights\u003c\/li\u003e\n\n\u003cli\u003eIntegrated aluminum alloy backing — uniform cooling without large additional heat sinks\u003c\/li\u003e\n\n\u003cli\u003eFour clearly marked power contacts (2+ and 2-) — simple connection, no risk of accidental reversal\u003c\/li\u003e\n\n\u003cli\u003e11mm COB die covered with a protective gel layer — increased mechanical resistance during mounting\u003c\/li\u003e\n\n\u003cli\u003eCompatible with standard 15-17V DC drivers, easy to integrate into new projects or repairs\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\u003c\/h2\u003e\n\n\u003cp\u003eThe 5W COB LED chip is powered directly by a DC driver with a voltage between 15V and 17V at a current of 300mA. Mounting is done by thermal or mechanical attachment of the aluminum backing to an appropriate heat sink, followed by connecting the four power contacts to the driver. No special processing is required — the compact 20mm size and clear polarity markings make integration quick even for DIY projects.\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 can I use for this 5W COB LED chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eA DC driver with an output voltage of 15-17V and a current of 300mA is required.
