The TCL COB series LED down light uses chip-on-board technology, where many LED chips are mounted together on a single module to create one smooth, uniform light source. The result is a soft, even beam with fewer visible hot spots, making it a popular choice for homes, hotels, shops, restaurants and offices where lighting quality matters. Down lights provide focused illumination from the ceiling and are widely used for general lighting, accent lighting and display areas. COB construction is also compact, allowing a clean and modern fitting design. As an LED product, it offers efficient operation and a long service life, which helps reduce energy use and maintenance.
