The Round Root Lantern Festival, also known as the Burning Lantern Festival, is an annual ritual held by disciples of the Gelug sect (Yellow Sect) of Tibetan Buddhism to mourn the passing of its founder, Tsongkhapa.

In the past, burning lanterns required a large number of lamps, which were difficult to prepare at the moment. Therefore, circular bulbs (a type of vegetable fruit with a shape similar to a white radish) were dug out of the center to make circular bulbs, which were enshrined in front of the Buddha's throne and placed throughout the temple. Now, electric bulbs are used instead.
