Washington, D.C. Lights
| If you've ever wondered about the illumination of the Washington Monument in your spare time, you're in luck, since the Washington Post just shed some light on the subject in a very good article by Philip Kennicott, Aug. 26th. If you're an old-hand at Washington field trips, you might recall the good old days, when no tickets were issued to visit the Washington Monument. Instead, you simply instructed your trusty bus driver to swing by the monument, periodically, in order to eye-ball the waiting line and jump in line at a judicious moment. You might, also recall, the monument would remain open until midnight, so even if the wait to get in was a couple of hours, students wiled away the time by making friends with others in the same boat. It was a win-win situation, a handy night-activity and good fun; alas, post-9/11 era arrived and everything changed. But I digress. While waiting in line at night, you would have noticed large cannisters of lights set into the ground. They were hard to miss, since bugs danced about in the light. The trouble with this old-school lighting system was that, well, not much light hit its intended target, the Washington Monument. In fact, as little as 20% of the light did. Enter Musco Lighting, which also has illuminated the Pentagon and the World Trade Center sites during operations, just after 9/11. Musco Lighting came up with a better idea: 1) shape the light with mirror-like fixtures that focus the light in a narrow cone, resulting in 80% of the light hitting the surface of the monument; 2)Less is more, so the new lights reduce energy use and your tax bill covering the cost!; 3) the lights are repositioned to poles removed at a distance from the monument, so bugs no longer dance nearby and the clutter-free design is effective. It's a clean, fresh look for the Washington Monument at night; oh yes, if you're wondering about the lights of the Capitol dome---no comment, since 9/11, this information is security-sensitive and not released to the public. Finally, if you're in town without your students (small site), hike over to 1100 Vermont Street, NW, at night and witness a fanciful display of light-emitting diodes, which cast shadowy images of passersby and, eventually, will include a grove of musical poles that, when touched, will "sing." | Big city, big lights |
