Throughout the south there are schools, universities and professional theatres with electrical equipment that has been submerged in flood waters from Hurricanes Harvey and Irma. They're biggest question is, "What can I dry out and use, and what do I have to replace?" NEMA (the National Electrical Manufacturers Association) has a guide for this (NEMA GD 1-2016 Evaluating Water-Damaged Electrical Equipment) that you can download here.
Earlier this year we started working with New York's Target Margin Theater on converting a two story warehouse into a new studio theatre, rehearsal spaces, and office space. Two acoustically isolated rehearsal rooms were built at the beginning of the summer. When bids for the resilient stage floor were twice as high as expected the team decided that TMT could build it themselves.
Kevin Willmorth has a long and interesting article on his blog in which he argues for the recognition of professional lighting designers, and what a professional lighting designer is and is not. The post echoes Chapter 1 of Designing With Light, and many of the things I've written in the book’s blog, including promoting the lighting design profession, the value of professional lighting design, the need for projects to use a professional lighting designer (here, here and here), and those other than professional lighting designers making design decisions, among other topics. I don't have much to add to Kevin's post, except to say that it's well worth reading.
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!
