Learn more about UL sponsoring this historic event as part of our ongoing public safety outreach.


UL continues to proudly sponsor the National Christmas Tree Lighting event in Washington, D.C., as part of our ongoing public safety outreach. On Dec. 6, 2013, President Barack Obama, First Lady Michelle Obama and their family lit the White House tree at a gala celebration, carrying on an American tradition started by President Calvin Coolidge in 1923. UL sponsors this important event as part of our dedicated efforts to educate consumers on how they can make their homes safer, especially during the holidays.
