As solid-state lighting (SSL) technology advances and becomes increasingly used in luminaires, the lighting industry has identified a need for more definitive standards to guide the design and development processes. The recently-drafted US Energy Star Program Requirements for Luminaires identifies two categories of luminaires: directional applications and non-directional applications.
