DOE Publishes New Report on Dimming LEDs with Phase-Cut Dimmers

U.S. DOE has published a new report, Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success. The report was created in response to issues raised about dimming by energy efficiency organizations and specifiers, and is based on experience from CALiPER testing and GATEWAY demonstrations. The new report reviews how phase-cut dimmers work, how LEDs differ from the incandescent lamps these dimmers were originally designed to control, and how those differences can lead to complications when attempting to dim LEDs. Such complications are often due to incompatibility between the LED source and the dimmer, rather than to any shortcomings in the LED source itself.
