DOE Report Releases Two New CALiPER Benchmark Reports

DoE recently released two new CALiPER Benchmark Reports; one comparing omni-directional incandescent lamps (A-type and small decorative, candelabra-type lamps) and their commercially available LED replacements, the other shows an analysis of halogen MR16 lamps and their commercially available LED replacements.

The results of both reports show a frustrating picture for LED replacements. Most manufacturers claim much too high values for their products. Very often the LED lamps to replace incandescent lamps produce only 10-60% of their claimed light output, while carrying claims such as “equivalent to a 25-W lamp” or “replaces a 40-W lamp” or “90% more efficient than a 60-W lamp.” MR16 LED replacement lamps were compared to 20W halogen lamps. Wide variations were observed in tested performance. Even the best performing LED replacement lamp doesn't reach the light output of the least efficient halogen lamp. DoE stated: For cases in which lower light levels are desirable, LED MR16 lamps may provide a more efficacious alternative to halogen lamps.

To help users better compare LED products with conventional lighting technologies, DOE conducts CALiPER testing of traditional (non-LED) lamps and fixtures. Benchmark Reports provide detailed analysis of test results for both traditional and LED products for a given application, comparing a range of standard lighting measures (e.g., power usage, light output and distribution, efficacy, correlated color temperature, color rendering index). Potential performance and application issues indicated by CALiPER testing results also are examined.
