LED Directional Lamps


May 19, 2014

This document provides an overview of the current performance of LED PAR-, BR-, R- and AR-shaped lamps, which were all investigated by CALiPER in 2012.

 

Directional lamps are a key component of focal lighting and are most often used in retail, hospitality, residential and museum applications. Conventional directional lamps are practical and relatively inexpensive, but higher-efficacy LED alternatives have emerged. This fact sheet discusses the attributes of conventional PAR-, AR-, BR- and R-shaped lamps and compares the performance of LED products to that of incandescent, halogen, CFL and CMH lamps.
