Don´t let yourself get confused by miniature dimensions – small SMT LEDs produce surprisingly strong light. SMT LEDs enjoy a big popularity because of their size but also thanks to a fast and simple assembly to PCB on automatic machines. In comparison to wire-leaded types, a vast majority of SMT LEDs doesn´t contain optics, thus
