EPA hosted a series of conference calls last November to inform the development of dimming requirements for consideration as part of the ENERGY STAR Lamps V1.0 specification development process. The work falls into two tasks, one focused on requirements and the other on test methods for meeting the requirements. The requirements and test methods will cover LED, CFL lamps and a variety of different dimmer products. The test procedures include the characterizations of dimming range, flicker and noise. The discussions were successful and a select set of labs are performing round-robin tests to improve and verify the test methods before the requirements are finalized.
Lumentra is currently participating in a series of extensive round-robin tests to help move forward the dimmer requirements. We will keep you updated on developments.
