Thoughts on Bi-Level Switching

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, [...]
