Best-in-Class List for LED Directional Lamps

The goal of this project was to develop a list of best-in-class for both PAR30 and PAR38 LED reflector lamps, that not only save energy, but also are likely to meet or exceed residential consumer expectations in their overall performance. In the case of lighting, this means excelling in visual parameters, compatibility with common controls, and cost-effectiveness. In the near term this will have the effect of pushing the market toward increased energy efficiency. In addition to the two lamp lists, a key innovation of this research project is the pioneering and robust methodology developed by the research team, with considerable input from PG&E, other funding organizations, and lighting efficiency stakeholders. This methodology enables relatively straightforward updates to the initial best-in-class lists of PAR30 and PAR38 LED reflector lamps. It also lays the groundwork to expand into a multitude of other lamp shapes, sizes and technologies. Note: On 3/7/2013 corrections were made to Table 1 as follows. The Weighting for CRI variance was corrected from '9' to '6', and the Weighting for Duv was corrected from '4' to '5'.
