From the Ithaca Journal:
The nightly spectacle of Niagara Falls lit up after dark just got more spectacular.
A $3 million upgrade saw the installation of 1,400 new high-tech lights called luminaires that beam brighter and more vivid rainbows of light from Canada onto the famous waterfalls.
Mixed together, the separate red, green, blue and white LED units can illuminate the waterfalls against the night sky in endless combinations that range from subtle hues to deeply saturated colors.
Perched on the upper level of an 1899 building known as “Illumination Tower,” the high-intensity system unveiled Dec. 1 replaced a bank of 21 spotlights, each 30 inches in diameter, that were equipped with colored gels.
