Like their name says, Surface Mount Device (SMD) LEDs mount on the surface of electronic boards. This is opposed to other LEDs, which physically go through the boards. Because SMD LEDs are much smaller, it is possible to put 3 different colored LEDs (red, green, and blue) in one lighting element. Using one LED to create 3 colors greatly increases resolution and improves overall image quality. Equally important, SMD LEDs produce more lumens for less energy. This means they are far more powerful and energy efficient than older LED lights.
