The TCL narrow border LED panel light in the TJ series measures 300 x 600 x 35 mm, a rectangular format that works well for linear lighting layouts in ceilings. The flat LED panel distributes light evenly across its diffused face, creating comfortable, low-glare illumination for offices, corridors, classrooms, shops, hospitals and hospitality spaces. A narrow border gives the fitting a slim, modern appearance, and the slim 35 mm profile makes installation straightforward where ceiling depth is limited. Rectangular panels are often combined in rows to light longer spaces evenly, giving designers flexibility. LED technology provides efficient, long-lasting lighting that helps lower energy and maintenance costs over time.
