Lighting Efficiency Standards are Changing Again

For most of history, lighting technology has been largely the same, especially when it comes to the standard incandescent bulb. But in 2007, as part of the Energy Independence and Security Act (EISA), the federal government set new efficiency standards for incandescent light bulbs.

Controlling LEDs

LED light sources offer energy savings, long life, excellent light quality, and new fixture options— allowing them to be used in almost any application. These advantages make LEDs an excellent choice for virtually any customer, but there are challenges associated with making sure that LEDs meet end-user expectations. Incandescent and halogen lighting, while inefficient, always offered highly predictable light quality with any control. In comparison, LEDs are much more efficient, but their dimming performance can widely by manufacturer and model.
