This is a demonstration of how lighting is changing with the advent of multi-color LED-powered fixtures. The wonderfully variable but sometimes non-intuitive color capabilities of LED-powered lighting gives designers the power to both radically and subtly manipulate color in a real-time basis. This session presents some of the basic science behind colour perception and the nuances of additive colour mixing. It shows how differences in emitter colour choices can affect the colour quality of fixture output. It introduces the concept of metamerism as it applies to mixing colour with light and presents some ideas for the intuitive control of colour mixing fixtures.

About Local IES Programs

Program Committee Chairperson: Bob Bridges

Each year your local IES section strives to keep you at the top of your lighting game by bringing knowledgeable speakers to you at our monthly program meeting events. Usually held over lunch, the format typically included some time to network with other local members of the Ottawa lighting community followed by lunch and 45-minute presentation by a guest speaking on a timely lighting or related topic. We work hard to find speakers from around the country and across the continent who are well respected and knowledgeable in their particular area of expertise.

If you haven't been to one of our events lately, we encourage you to join us at our next meeting. It is this Section's mission to serve its members and the Ottawa lighting community by bringing together those with lighting knowledge and those who can benefit from the sharing of that knowledge. 

We generally hold our program meetings (technical luncheons) on the last Thursday of September, October, November, February, March, April, and June. If there are topics you think need to be covered, feel free to reach out to our program chair by sending a message to This email address is being protected from spambots.
