What is the difference between SMD and COB LED lights?

Light-emitting diodes (leads) are semiconductor devices that emit light when an electric current is passed through them. Light is produced when particles carrying electric currents, called electrons and holes, combine in a semiconductor material. ​Essentially, leds are tiny beads of light that are easy to install into a circuit. But unlike incandescent bulbs, China wateproof …
