外滩景观灯光将进行节能改造 - 2018年09月04日

The conventional light bulbs along the Bund will be replaced by LED lamps before the end of the year to reduce power consumption while retaining the classic color temperature.
Shanghai began using high-power sodium lamps to illuminate the exotic architecture in the early 1990s.
The lamps have been a big success, lighting up the magnificent buildings every night, but unfortunately consume a lot of power.
