Some of the outdoor lighting decorations on buildings' walls in Hong Kong painstakingly focused the lightings to the sky. Their designs surely increased the light pollution! Reporters asked why there are extensive up-lighting beams at night at the roof top of a skyscraper at Central. The designer replied that he would like to use the upward beams to being out "Heaven and human are the one" concepts. From our point of view, this skyscraper not only cannot achieve the concept, but the lightings also masked up the starry night and separated heaven and human!
At night, Two International Finance Center in Central likes a huge torch. The light emitted by the building causes serious light pollution and wastes many energy.
Another "huge torch" near Sheung Wan equips upward outdoor lightings. It is easy to see that the clouds just above the building are brightened and reflects human light and cause light pollution.
Apart from tall buildings, construction sites also installed extensive upward lightings. Taken at the middle of 2006, two light beams emitted from a construction sites in Tai Kok Tsui are clear in this picture at the right hand side.
People complained about the testing of light fibers decorations of The Legend at Jardine's Lookout, located at the old site of Tiger Balm Garden in Tai Hang, Hong Kong Island. People were annoyed by the large intensity and glittering of the decorations.
