Why does fluorescent light come on when starter removed?

Fluorescent lights rely on a starter to help initiate the arc between the electrodes. When the starter is removed, it can cause a change in the electrical circuit, allowing current to flow more freely and potentially enabling the fluorescent lamp to ignite without the starter's assistance. However, this is not a standard or safe operation, as it can lead to inconsistent lighting or damage the fixture. It's important to use fixtures as designed for safe and reliable operation.
