About bulb replacement to "Landmark Light" summer version

There are two types of light-up "Landmark Light" at Tokyo Tower: a cool silver image summer version and a warm orange image winter version.
At the beginning of July this year, we plan to replace the bulb with the "Landmark Light" summer version. (There is a possibility of postponement due to bad weather) In addition, the "Landmark Light" summer version will be lit until early October (planned) when it returns to the winter version again.
