ESTA and USITT announce the New World Rigging Symposium, on March 13-14, 2018 in conjunction with the USITT Conference and Stage Expo 2018 in Ft. Lauderdale, FL. The Symposium will provide an opportunity for riggers and those interested in the live entertainment rigging industry to network, discuss current issues and new technologies, and help shape the future of the industry.
ANSI/IES RP-16 Nomenclature and Definitions for Illuminating Engineering has long been one of the two major documents defining terms related to lighting design (the other is CIE ILV: International Lighting Vocabulary). RP-16-10 (the 2010 version of the Recommended Practice) is now available online as a searchable database. From the first page you can click on terms to see the definition and you can also search by keyword. If you don't already own RP-16 bookmark this now!
Last year the AMA issued Policy H-135.927 Human and Environmental Effects of Light Emitting Diode (LED) Community Lighting, which recommended, among other things, that LED outdoor lighting should have a CCT of 3000 K or below. The AMA made this recommendation thinking that lower correlated color temperatures contain less blue light, which can disrupt circadian rhythms.
Like other lighting technologies, the color or chromaticity of light emitted by an LED can shift over time. To address the challenge of developing accurate lifetime claims, DOE, together with the Next Generation Lighting Industry Alliance, formed an industry working group, the LED Systems Reliability Consortium (LSRC). A new LSRC report, LED Luminaire Reliability: Impact of Color Shift, focuses on chromaticity. The purpose of the new report is not to define limits for specific applications, but rather to enable a better understanding of how and why color shifts, and how that impacts reliability. Download it and take a look.
This photo is from this morning's rehearsal of the Tony Awards at Radio City Music Hall. The show airs tonight on CBS and is hosted by Kevin Spacey. Our own Ed McCarthy is the lighting director. It's going to be a fun show. Watch it!
I’m sad to share the news that Lenore Doxsee, one of my oldest and dearest friends and a Studio T+L associate, passed away on Friday, May 19. It’s hard to say if Lenore was more of a theatre artist or a theatre teacher because she excelled at both, loved both, and wouldn’t give up either. In her last few weeks, she designed scenery and lighting for a 5-hour play in New York, and gave many additional hours of her time supporting and then critiquing her student’s final projects.
One of America's greatest and most prolific theatre architects, Hugh Hardy, passed away on Thursday at the age of 84. We had the great privilege of being the lighting designers for Hugh and his team on the renovation of the public spaces of the New Victory Theatre on 42nd Street, which will open later this year. His wit, generosity, and knowledge were always evident and always appreciated. Here is his obituary in the New York Times.
I have a current project with a green wall, aka living wall, and other greenery in the space. I’ve been given conflicting information about the lighting requirements I need to meet are and how to measure them, so I did some research. This isn’t definitive, but here’s what I’ve found.
Measuring and describing the brightness of colored LEDs is an increasingly important part of a lighting designer’s practice. They are used more often, and in more types of projects, than ever before. Yet, we don’t have an accurate method for understanding exactly how much light is being produced and how bright it will appear. It’s a problem that the lighting industry needs to solve, and soon.
