Over the entire commercial range of LEDs – from near-ultraviolet (360 nm) to nearinfrared (950 nm) – there is no consistency in defining specifications. This makes it challenging for users to compare the relative efficiencies of LEDs in the visible region to LEDs outside it. Particularly in the visible region, it is difficult for users to specify LEDs in a manner that correlates well to the system application. This article provides an overview of the important LED performance parameters, enabling users to select the product that best meets the needs of their particular application.
