Taipei, Dec. 20 (CNA) Christmas light displays around Taiwan are not putting a burden on the country's electricity supply because many use energy-saving LED lights and are operating at a time when demand for power is not at its peak, the state-run Taiwan Power Co. said Monday.

"Christmas light bulbs are consuming relatively small amounts of power. There is no problem with the electricity supply," Taiwan Power spokeswoman Tu Yueh-yuan told the Central News Agency.

Christmas light decorations have come under fire from environmentalists, with groups in Hong Kong saying that lighting decorations on the walls of buildings in the Victoria Harbor area consumed enough electricity to run 330 four-person households for a year.

Tu dismissed such concerns. She said Taiwan had seen record use of electricity over the summer due to a surge in the use of air conditioners to combat the heat, but that was not an issue during the winter.

Many shopping malls and local governments in Taiwan have put up colored lights on the street or on Christmas trees to mark the arrival of the Christmas season.

Citibank Taiwan, for example, worked with the Taipei City government and the Finland Trade Center, a Taipei-based foreign trade office, to install blue lights covering trees and overpasses in a 400-meter section of the Xinyi shopping district in Taipei on Dec. 18.

The Tainan County government has also installed eight long lines of "light dots" on the square in front of the county government office building, with trees on either side of the square also decorated with lights.

More such celebrations are expected as Christmas approaches.

Administration officials in the Tri-Mountain National Scenic Area in central Taiwan's Taichung County plan to decorate a 20-meter-tall cedar with 90 13-meter-long LED lights in front of the Lishan Guesthouse on Dec. 24.

The tree, located at an altitude of 2,000 meters above sea level, will become one of Taiwan's highest altitude Christmas trees, along with one at 2,116
