DOE’s main solid-state lighting proponent, Jim Brodrick, recently reported in from the DOE SSL workshop, just held in San Francisco, for those who couldn’t make it with one of his best letters (“Postings: From the Desk of Jim Brodrick”) to date. The conference presentations, by the way, should be published on the DOE SSL website [...]

NEMA’s Lighting Systems Index (LSI), which reflects sales of lighting equipment by NEMA members, dropped 4.8% between the third and fourth quarters of 2008. Lighting shipments fell six of the last seven quarters, but this is the biggest drop since 2001, bringing the index 16% lower than its cyclical peak level in early 2006 and [...]

Multilevel switching and personal dimming are often lumped together because the goal is the same–providing users a manual choice of light levels. The 2003 Advanced Lighting Guidelines, published by the New Buildings Institute, says they both save about 30% in energy. There is evidence that bi-level switching saves much more energy than personal dimming control, [...]
