Lantern Festival 中文譯做什麼

If you are from Hong Kong, you are right.
But for Taiwanese Lantern Festival is 元宵節 because Taiwanese do not 提燈籠 in 中秋節.

In order to make it clear, people usually call 中秋節 Mid-Autumn Festival or Mooncake Festival

yes,you are correct.

你的問題就像「馬是白馬嗎？」一樣。
中秋節在中國來說，祇是眾多的lantern festivals之一吧！
Lantern 是泛指燈籠，通常的燈節是陳列各式燈籠的節日罷！
