LEDucation Postponed

Due to growing concerns of COVID-19 in the lighting industry and the New York community, the Designers Lighting Forum of New York is postponing the LEDucation 2020 Trade Show and Conference that had been scheduled for March 17 - 18.

LEDucation Update

LEDucation this year is on March 17 and 18 at the New York Hilton Midtown where our Jason Livingston be part of two presentations.  The first, at 9 am on Tuesday morning with Wendy Luedtke of ETC, is a seminar called Specifying Color Rendering with TM-30's New Annex E.  The session presents the new ANSI/IES TM-30 Annexes E and F, which apply recent research to identify three color rendering design intents (Fidelity, Preference, and Vividness) and provides specifiers with TM-30 values to achieve them alone or in combination. Our goal is to increase awareness of Annexes E and F and to help attendees better understand their contents and use. The seminar is most appropriate for people with some prior knowledge of TM-30, although there will be a brief TM-30 overview for those who are new to the topic.

Using TM-30 to Improve Your Lighting Designs

Recently, ANSI/IES TM-30 was improved with the addition of Annexes E and F.  Annex F reviews and summarized five studies that explored using TM-30 metrics to predict subjective visual outcomes.  Annex E uses that research to establish recommended specification criteria when the designer's color rendering goals are Preference, Vividness and/or Fidelity.  

Do LEDs Make You Look Orange?

Last Thursday Donald Trump spoke to a group of Republicans in Baltimore.  One of the things he said caught my attention: “The lightbulb. People said what’s with the lightbulb? I said, here’s the story.  And I looked at it, the bulb that we’re being forced to use, No. 1, to me, most importantly, the light’s no good. I always look orange. And so do you. The light is the worst.”

TM-30 Guidelines Presentation at IES Annual Conference

This year's IES Annual Conference in Louisville, KY runs from August 8 to 10 and will include two events to help specifiers better understand ANSI/IES TM-30 IES Method for Evaluating Light Source Color Rendition.  

Misunderstanding CRI

Last Friday I took my class on a visit to a fixture manufacturer’s showroom.  The visit was pretty successful, but I had one issue with the information that was presented.  This manufacturer’s rep presented their CRI 80 and CRI 90 products by saying that CRI 80 dulls colors and CRI 90 makes colors “pop”.  I can’t blame him too much, after all it’s a common misconception that higher CRI is “better.”  However, it’s not true so let’s take a look.

Understanding and Applying TM-30

Studio T+L's Jason Livingston will be presenting Understanding and Applying TM-30 to the New Jersey section of the IES on Tuesday, March 19th.  If you're interested in attending you can register at http://www.iesofnj.org/TM3015.html.
