SSL Basics

Solid-state lighting (SSL) differs from other kinds of lighting in that it's based on light-emitting diodes (LEDs) or organic LEDs (OLEDs) instead of filaments, plasma, or gases. In addition to having the potential to be more energy efficient than any other existing lighting technology, it also has a number of other advantages—including directionality, controllability, vibration resistance, long life, color tunability, and aesthetic appeal. But SSL is still at a relatively early stage in its development, and a number of hurdles need to be overcome if it's to fulfill its considerable promise.
