Tourism Ireland has what's called a "Global Greening" campaign and for St. Patrick's Day this Sunday that "greening" will come to Niagara Falls.  Both the American and Horseshoe Falls will be lit in green for 15 minute intervals every hour on the hour from 7 pm to 2 am.

It's yet another opportunity to experience the new enhanced LED lighting technology that was unveiled at the Falls in 2016.  These new lights not only provide more intense lighting and a broader variety of colors, it's done using 60% less energy.

Both the American and Horseshoe Falls have been illuminated at night since 1925.
