ABSTRACT
NIST maintains the standards for units of light measurement such as watt,
lumen, and candela. The definitions of these units and how NIST establishes
such standards will be presented. Further, the energy efficiency of light sources,
in particular, the state-of-the-art white light-emitting diodes (LEDs) and solid-state
lighting (SSL) will be discussed. SSL is expected to reduce the total energy
consumed by lighting to half and to lead to tremendous energy savings to the
nation and world. Challenges in achieving 200 lumens per watt, design of spectra,
and color quality issues will be discussed.
