The National Electrical Manufacturers Association (NEMA) has published SSL 3-2011 High-Power White LED Binning for General Illumination. This standard, first published in 2010, was produced by NEMA’s Solid State Lighting Section. SSL 3 offers categorization areas (bins) for chromaticity (colors), forward voltage measurements (an electrical designation), and luminous flux (light output) for light-emitting diodes (LEDs) [...]

The National Electrical Manufacturers Association (NEMA) Emergency Lighting Section has launched its Premium Exit Sign Program, which establishes standards for and encourages the use of high-performance exit signage. Unlike other NEMA Premium programs, this effort does not focus strictly on energy efficiency. Instead, the goal of the NEMA Premium Exit Sign Program is to increase [...]

I’m pleased to announce that I have finally completed the long awaited (by my publisher) update to The Lighting Management Handbook, which came out in 1994, with this 300-page book about redesigning existing lighting systems: Lighting Redesign for Existing Buildings.
