2012 Reports

  • CALiPER 2012 Year in Review
    The CALiPER program has tested more than 500 products since its inception in 2006, revealing a variety of performance trends, holding manufacturers accountable for claims, and identifying concerns that limit adoption. Over the past six years, the LED marketplace has changed substantially; previously relegated to niche status, LED products are now a viable alternative in many product categories and market share is expected to grow rapidly. This document summarizes recent testing results and provides an overview of multi-year trends. (3 pages, December 2012)

  • Application Summary Report 19
    Report 19 reviews the independently tested performance of nine LED linear pendants and also evaluates a collection of 11 linear pendant products available in both an LED and fluorescent version. In general, the LED versions were more efficacious, but sometimes had a different luminous intensity distribution, poorer color quality, or different lumen output than their fluorescent counterparts. (19 pages, October 2012)

  • Application Summary Report 18
    Report 18 reviews the independently tested performance of 17 LED recessed wallwasher luminaires. Overall, the LED products were found to be comparable to conventional wallwashers using a 32 W CFL or 20 W metal halide lamp, and several products were measured to have lumen output equivalent to 42 W CFL or 35 W metal halide lamps. (21 pages, October 2012)

  • Application Summary Report 17
    Report 17 analyzes the performance of a group of six LED products labeled as AR111 lamps. Results indicate that this product category lags behind other types of directional LED lamps but may perform acceptably in some applications and provide some energy savings. (24 pages, August 2012—Revised November 2012)

  • Application Summary Report 16
    Report 16 reviews the independently tested performance of 13 LED products labeled as BR30 or R30 lamps. Results show substantial improvement versus earlier CALiPER testing of similar products, but indicate the need for a broader range of LED products in terms of lumen output and distribution type. (26 pages, July 2012)

  • Application Summary Report 15
    Report 15 of testing analyzes the performance of a group of LED floodlights that mirrors the range of conventional luminaires designated as floodlights. Results provide several key takeaways regarding the future growth necessary for LED floodlights to compete with and overtake conventional products. (23 pages, May 2012)

  • Application Summary Report 14
    Report 14 of testing, focusing on LED downlight retrofit units, provides an overview of photometric performance results and compares the results to similar products that use conventional light sources, results from earlier rounds of CALiPER testing, and manufacturer ratings. (29 pages, March 2012—Addendum December 2012)
