 The tree was decorated with 2,000 five-watt green lamps (not bulbs) symbolizing "Hope," as well as 500 "twinkle lamps" and white ornaments.Due to the ongoing energy crisis, the tree was only lit from dusk to midnight from December 15 to December 26, and from dusk to 10 P.M. from December 27 to January 2.This achieved a further 74 percent reduction in energy use.
