Energy Conservation Program: Test Procedure for Metal Halide Lamp Fixtures

The U.S. Department of Energy (DOE) is initiating a data collection process through this request for information to consider whether to amend DOE's test procedure for metal halide lamp fixtures (MHLFs). To inform interested parties and to facilitate this process, DOE has gathered data and identified several issues associated with the currently applicable test procedure on which DOE is interested in receiving comment. The issues outlined in this document mainly concern updates to industry standards and potential clarifications to the existing test procedure for MHLFs. DOE welcomes written comments from the public on any subject within the scope of this document, including topics not directly outlined in this RFI. DOE also welcomes comments on any additional topics that may inform DOE's decisions in a potential future test procedure rulemaking, such as methods to reduce regulatory burden while ensuring the procedure's accuracy.
