Michigan State University has announced the results of a long-day lighting (LDL) research project at Wing Acres Dairy in Barry County, MI. Researchers from the school’s Biosystems and Agricultural Engineering Department worked with the Michigan Milk Producers Association (MMPA) to study the implications of LED-based LDL on milk production, and the study indicates an 8% increase over the course of a year.
Bright Light Systems, a leading manufacturer of Light Emitting Plasma (LEP) luminaires and wireless lighting controls, has announced the completion of a lighting upgrade project at the Port of Seattle Terminals 90 and 91. These terminals provide mooring for cruise ships as well as commercial workboats and fishing vessels.

The guidance covers mandatory and randomly-selected tests and defines limited cases in which verification testing can differ from the original certification testing.
The EPA spent the summer and early fall finalizing the Lamps V1.1 specification. That document includes slight changes from the Lamps V1.0 specification published in the fall of 2013. For now, lamps can be tested to either document while the agency works on the next lamps specification. Continue reading
