Dimming Systems Characteristics
Northwest Energy Efficiency Alliance commissioned a study to delineate the characteristics of 18 dimming systems as part of its Luminaire Level Lighting Control initiative. In theory, adjusting the light level by dimming 15 percent at the control station will have that intended effect (light level or power consumption reduction) at the light source or driver.…
