Niagara Upgrades to LED
The nighttime illumination of Niagara Falls recently unveiled LED lighting upgrade that replaces a 20-year-old halogen system.
As noted by the Niagara Falls Illumination Board, the LED enhancement — price tag: $4 million or about $3.1 million USD — will reduce related energy costs by as much as 60 percent (the new lights consume 52 killowatts of energy compared to the 126 kW used by the halogens) while illuminating the falls with a vastly larger spectrum of colors that are noticeably richer and more robust. As for the intensity and quality of the kaleidoscopic light itself, the LED luminaires shine anywhere from three to 14 times brighter than their incandescent predecessors depending on the color being projected. Compared to the previous bulbs, which sported a 1,900-hour lifespan, the LEDs will shine bright for up to 25 years.
The new lighting system will consist of 1400 individual luminaires broken into 350 zones of control across both falls. Each individual control zone is equipped with separate Red, Green, Blue and White LED luminaires (RGBW). When used together these separate colored RGBW luminaires will mix on the falls to create endless color combinations. The use of White LED’s in the color mixing scheme will allow one to move between deeply saturated colors to subtle hues of color to allow for more natural looking effects.
Over 185,000 feet of conductors will connect the 1400 individual luminaires to five 10 feet tall racks of individually addressed controllable drivers. The remote mounted drivers are indoors and easily accessible reducing the need for servicing drivers that would otherwise be internal to the luminaires out in the field.
