Summary
[edit]DescriptionLED lighting modules of Tilikum Crossing - Portland, Oregon.jpg | Three of the 178 LED lighting modules on the Tilikum Crossing bridge, in Portland, Oregon, which illuminate the bridge's cables and towers at night. Each of the 178 modules includes around 36 LEDs. (TriMet routinely describes the lighting system as one in which "178 LED lights" illuminate the bridge, which is somewhat misleading, as the number of LEDs is actually more than 6,000, and 178 is merely the number of lighting pods, or modules, and the use of "lights" to refer to these is ambiguous. Some mainstream media sources have written "178 LEDs" [without "lights"], which is definitely inaccurate.) |
