Caliper 2012 year in review

The US Department of Energy (DOE) has released a year-in-review of its Caliper program, and suggests that LED products are becoming more efficient, less costly, and producing more light than ever before. In 2012, Caliper reports focused on a single product type, rather than using a number of different lamps and luminaires in a single summary report. By doing this Caliper could provide more in-depth analysis of the performance baseline of conventional products and the expectations for LED products.
