Hopefully by now you’ve heard about Grand Central’s Holiday Light Show, one of the final events in this celebratory centennial year. Grand Central has hosted several holiday light shows in the past, but this year’s is most certainly my favorite. Taking over the Terminal’s west windows, LED lights turn each individual window pane into a “pixel” of color. In concert, all of these “pixels” can display colors, letters, and even basic shapes.
Behind the scenes: a Textilene scrim hangs in each window pane, onto which LED lights are projected. The windows on the west wall contain over 350 window panes, so setup was a daunting task. I wasn’t quite sure if walking behind the setup would be visible from below, so I didn’t!
The light show that you see each night, starting at 5 PM and continuing to 11 PM, is a collaboration by several groups. Sponsored by Toshiba, the show was designed by Michiru Tanaka, a lighting designer that has worked with Toshiba on several lighting projects. Bestek Lights brought the concept into the real world with LED light fixtures, and fabricated everything required to hold the lights. All of that work had to abide by landmarks preservation guidelines, as well as safety guidelines, since behind the window panes are walkways used by employees.

Because the window panels are a major source of light in the main concourse during the day, one of the requirements for the installation was that it could not block the sun. After several trials, it was decided that Textilene scrims would be hung in each window panel. The scrims would allow the LED light to be reflected onto it for the show, but would also allow sunlight to pass through during the day. Below each scrim is a Stagebar 54, a light fixture that contains 54 LED lights in five colors – red, green, blue, amber, and white. A total of 354 of these fixtures were installed to create the grand effect you see in the show.
If you haven’t gotten a chance to see the light show yet, you have until December 26th to check it out (which is definitely worth it). The thirty minute shows run continuously from 5 PM to 11 PM each night. Note that you can see the show from inside the main concourse, as well as from outside the building on Vanderbilt Avenue.
