We’ve reviewed what standards are and how to find them, but who wrote them?

Standards (which can often take years to write) are written with balanced input from experts who are part of our technical committees, each with their own specialized knowledge. by @the_iesorg

At IES26 The Lighting Conference, we took lighting education out of the meeting room and into the field.

Attendees got hands-on with illuminance, luminance, and spectral measurement tools—exploring the hotel and surrounding spaces to see, measure, compare, and better understand lighting in situ... Because sometimes the best way to understand light is to get out there and measure it yourself.

More hands-on learning. More shared experiences. More reasons to be in the room (and on the walk) with us. See you at IES27, Aug 19-21 in Detroit! by @the_iesorg

Join us Thursday, September 24 at 12:00pm US Eastern for "Coves Coves Coves" with Coffield King and Barrett Newell. Register at ies.org/webinars

Cove lighting is widely used in different ways throughout the built environment. From early festoon creations through neon and linear fluorescent to today’s ever shrinking LED products there are some spatial requirements that are repeatedly successful. This presentation will take a quick but deep dive into cove lighting from a number of different perspectives. Users will come away with a better understanding of successful digital and physical requirements beyond the standard sectional detail.

Free registration for members, $29 USD for Non-Members. Participants will receive one (1) IES continuing education credits (CEUs). by @the_iesorg
