LEDs with a high luminous intensity typically have a narrow apex angle. Similarly, LEDs with a wide apex angle typically have a relatively low luminous intensity. The cause for this relation is ... LEDs of a specific class (for example, "high flux") all produce roughly the same amount of luminous energy. However, when a LED emits its total energy in a narrow angle, the intensity will be greater (in the direction of that angle) than when the same energy had been emitted over a wide angle.
