IES Webinar: Solving LED Dimming Issues in Retrofit Projects
Oct 18 @ 12:00 pm – 1:00 pm

IES WebinarsLEDs are the go to light source for the replacement of existing lamps and luminaires providing a significant reduction in energy and an extended lifespan. LEDs can fit any form factor, and are extremely malleable compared to what we’ve been using in the past. However, dimming LEDs require careful coordination of lamps, drivers and controls to ensure proper performance. The session walks through dimming expectations for LEDs vs. incandescent such as dimming floor, color temperature, and linearity; the most common problems with LED dimming such as power line noise and how to address them. Participants to this webinar are eligible for one (1) IES Continuing Education Unit (CEU).

IES Webinar: A New Measure of Color Discrimination
Nov 15 @ 12:00 pm – 1:00 pm

Color rendition is commonly considered within three conceptual frameworks; color fidelity (the rendition of objects such that they appear as they would under a familiar reference illuminant), color preference (the rendition of objects such that they appear pleasant, vivid, or flattering), and color discrimination (the ability to distinguish colors of slightly different hue when viewed simultaneously). Color discrimination has been studied less frequently than color fidelity or color preference, though it is no less important. This presentation will summarize the previous literature on color discrimination and discuss recent work in this area. A recently published study by the current speaker will be discussed, which dispels the conventional wisdom that gamut area is a predictive color discrimination metric. This presentation will detail a new measure of color discrimination, which shows strong predictive ability of experimental results. Participants to this webinar are eligible for one (1) IES Continuing Education Unit (CEU).
