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.
This week I'll be focusing and setting light levels in a corporate board room. The photo below shows the installation and testing of a cove illuminated with RGBW LED fixtures. The second photo shows the installation of a hard dropped ceiling with downlights surrounding a luminous ceiling.
Sometimes the New York Times is oblivious and yesterday was one of them. In an article titled Lighting a Room, Simplified the author wrote about the importance of lighting in the home. In preparing the article, she spoke to and quoted four interior designers, one fixture manufacturers and one professional lighting designer. In addition, all eight of the photos in the article are taken during the day, so they're nice illustrations of the use of windows and daylight in residential interiors but terrible illustrations of electric lighting, which is the topic of the article. They seem to be marketing photos for particular lighting fixtures, not examples of good lighting.

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!
In a project meeting yesterday a team member said that LED stage lights would save the owner money. While there are many reasons to include LED lights in a theatre's equipment inventory, cost savings is not one of them. We've written a white paper, LEDs In Stage Lighting, that includes an economic analysis and simple rate of return. Get a copy here.
